DisplayLink BVU195 USB adapter

tnoonkes — Wed, 16 May 2012 12:54:21 -0400

I have a Lenovo T410 with the NVIDIA NVS 3100M. I recently bought a USB to DVI adapter so that i could use a 3rd monitor with my laptop. *(Laptop monitor is primary with 2 other samsung monitors attached, one via DVI input from laptop dock, second from the USB adapter.) I have updated my video drivers to the latest drivers but when i install the DisplayLink software for my USB to DVI, my computer crashes every time when i reboot windows. Please let me know if there is any fix for that adapter and NVS 3100M. Thanks.

rootfs tegra3 package

tankcr — Sat, 12 May 2012 07:03:05 -0400

Hi all, I am trying to build a Ubuntu for the TFP but I was wondering if there is a prebuilt rootfs package for the tegra3, and if not does anyone have any suggestions for building one?

Quadro FX3700 reporting "GDI Generic" version 1.1.0 ?!?

bsenftner — Thu, 03 May 2012 15:17:21 -0400

I have a combo web server / hi-compute server inside a Windows Server 2008 R2 machine. The physical machine is in a collocation, and I access it via the web sites it serves and via Remote Desktop Commection (RDC) when installing, configuring & maintaining the system.

I have a few programs which attempt to create OpenGL contexts, render into the framebuffer, copy the results, and write them to an image file. However, the rendered results are black or noise filled images.

I installed the "Geeks3D GPU Caps Viewer" (build 1.16.0 from April 11, 2012) and it is reporting, from a RDC connection, GL_RENDERER: "GDI Generic", GL_VERSION: 1.1.0, GLSL version: N.A.

It looks like something additional, or extra is required to get Accelerated 3D Rendering in a headless context under Windows Server 2008 R2. Can anyone point out any information or references to help out?

Failed lunching kernal

Saouli — Thu, 03 May 2012 19:52:11 -0400

Hi again
after all what i learned about cuda and how to use but still not enghoth well i wrote cuda kernal for ray casting to render some DICOM files it's k
I used shared Memo and texture memo


void CallCUDAKernel(dim3 gridDim, dim3 blockDim,unsigned int *Outputi, int *Winds,float *Spacing, int *VolDim,float *Boxmin,float *Boxmax,float *UP,float *AT,
	                                float *OThreshold,float *Omega,float *angle, float *CamPos)

{

	RaycastingRender<<>>(Outputi, Winds,Spacing, VolDim,Boxmin,Boxmax,UP,AT,
	                               OThreshold,Omega, angle,CamPos);
}

somthing like that before i call my cernal i do allocate all the varable on globale device using
cudaMalloc and cudaMemocpy Note some varaible should be cpy from Host complex structr to device

I dont know why but my Kernal stop and give me cuda kernel : (11) invalide argument error
cuda kernel invalide argument error

Getting started, price-worthy hardware?

AniSkywalker — Fri, 04 May 2012 18:15:05 -0400

Hi!

I'm new to both this forum and CUDA but it is very much in my line of interest. I already know both asm and some GPU-programming (float point arithmetics etc) with asm.

I want to start with CUDA-programming. I'm searching for price-worthy and CUDA 4 compatible hardware. Since I am very new to the subject, I'd like to be directed to hardware choices that gives relevant experience when writing CUDA code. That is, if double gpu or double cpus are beneficial, I'd like to be pointed towards good and price-worthy solutions there. If a single gpu/cpu solutions is a good enough place to start and get experience (say 35000-50000 lines of code) then I'd go with it. And if if there is some solution that works for now and is upgradeable, I might go with it.

Just to be clear, I wouldn't ask here if I wasn't entirely new to this, so please don't mock me if some of my questions are pure stupid. I just don't know better ways to form them right now...

Which version of the NVAPI should I use with my Quadro FX 570 card?

braggo — Fri, 04 May 2012 15:19:38 -0400

Dell desktop, Windows 7
Nvidia Quadro FX 570

I am currently using R295 February 2012 release of the NVAPI and some of the functions are returning an error code -9 NVAPI_INCOMPATIBLE_STRUCT_VERSION.

Specifcally, the NvAPI_DISP_SetDisplayConfig() and NvAPI_DISP_GetDisplayConfig() when I pass in a NV_DISPLAYCONFIG_PATH_INFO struct.

Here are my debug print outs:

NvAPI_Initialize(): mStatus = NVAPI_OK

NV_DISPLAY_PORT_INFO_VER = 65580
NV_DISPLAYCONFIG_PATH_INFO_VER = 131100
NV_DISPLAYCONFIG_PATH_ADVANCED_TARGET_INFO_VER = 65664
NvAPI_SYS_GetChipSetInfo(&mChipSetInfo): mStatus = NVAPI_OK
-- ChipSet Info --
Device Id = 10720

NvAPI Version = NVidia Complete Version 1.10
NvAPI_SYS_GetDriverAndBranchVersion(): mStatus = NVAPI_OK
GPU Driver Version = 27533
Branch String = r275_21

Is the GPU driver version incompatible with the API version macros?

Thank you in advance for your help!

Issue using NSight 2.2 rc2 with VS11

diver182 — Wed, 02 May 2012 15:19:27 -0400

Hi,

I installed VS11 (Ultimate) beta on my Win7 machine,
after that the 4.2x SDK and then Parallel NSight 2.2 rc2.
The NSight installer claimed to have made modifications to the VS11 installation.
But I can neither find the NSight menu on the upper pane nor the templates
for creating a cuda 4.2 project.

Do I have to adjust anything to make it work or what did I miss?

GAI sample games don't work, GT240 CC1.2

Pawe — Thu, 03 May 2012 08:07:03 -0400

Hi,
I am working on parallel AI game-tree-search project and just wanted to run examples from NVIDIA GAI project as there is everything I would need. Unfortuanately sample applications do not work proparly on my PC (with CC=1.2, windows x64, and latest drivers installed). Actually I can only run a game with CPU AI. When GPU is toggle only random player plays and always wins. I must be sure that these libraries work proparly so I can write similliar one for another game in my project. Please help!

Optix with Geforce GTX 680 & 690

kaufmann — Mon, 30 Apr 2012 13:15:04 -0400

Has anyone tested Optix with the GTX 680 yet and can you report performance increases/decreases compared to a 580 / 590?

Will Optix 2.5 work with two GTX 690 right from the start next week or will we have to wait for an update / updated drivers?

thanks

I need a shader

Kamlah — Tue, 03 Apr 2012 07:52:38 -0400

Hi All,
I would like to get some help. I work in a TV as a graphic artist. Here we use a virtual studio system, where I need to create or somehow solve the problem showing frozen glass like material. The point is that the objects behind need to be blured. I found a good example here: http://www.polycount.com/forum/showthread.php?t=87743
The first picture shows some teapots behind a glasslike surface. Thats what I need.
My biggest problem is that iam a total lama for the Cg topic. I started to learn and go into deep into the topic, but now i see that it is much more complex as i thought.
So i would be really thankful ...
The studio render engine use Nvidia cards but I dont know the exact parameters now. If necessary i look for it.
thx

Will you please tell me which development kit can be used to develop Tegra 3? I am not sure why CUDA on ARM Development Kit is used for, many of them tell me that its not for Developing Tegra 3.

Thank you.

Tesla Differences

hab82 — Thu, 19 Apr 2012 03:25:55 -0400

Specifically I have 6 M2050's and 3 C2050's. In performing bandwidth tests I was surprised by a significant difference (aprox 50%) (5000 vs 3600) (M vs C) in pinned memory bandwidth. I was also surprised that the M reported pcie X16 Gen 2 where C reported X8. This was in the same slot so it is definitely the GPU's causing the difference. Yet in literature the both have the same specs. Does anybody know why the difference, and preferably a source of a fix for the C2050's. I purchased all of these used so I do not have an OEM connection.

Driver with realtime linux kernel?

int512 — Sun, 15 Apr 2012 08:06:23 -0400

I tried to compile and use a patched nvidia kernel module(patches provided here), the module loaded(the gpu fan slowed down, without a driver it runs on max) but the screen remained black and CTRL+ALT+F1 -F8 didn't do anything, the splash logo never appeared(it does with generic debian kernel). Kernel version is 2.6.33.7.2-rt30(same as in the guide), driver version is 295.40(those patches are for 295.2, that might be a problem). The way I tried was to pass -x to the .run file, cd into 295.4/kernel directory created by the installer, apply the patches(didn't return any errors) boot in to a realtime kernel and pass the -K option to the nvidia-installer, it installed without errors, after a reboot the fan slows down and the screen remains black. Will nVidia provide support for RT kernels with a command-line option?

Please give us the HAL compontents

r00t4ev3r — Thu, 05 Apr 2012 04:50:38 -0400

Why are you not going to open source the HAL components? Without these components, the Rome are not working well because many things are missing. What's so hard about to simply release the drivers?
Android is known for its large community, what would android be without the numerous custom roms?
It's not that there are 10 people which think like me, there are hundreds or even thousands.
Just read this Thread: http://forum.xda-developers.com/showthread.php?t=1347118
Please think about the community and about the future, because if you go on like this, like you are now doing, many people do not buy Tegra devices anymore.

Sorry for my English, but i think you understand what i mean.

Using multiple Geforce cards with OpenGL (Windows 7)

JohnZo — Thu, 19 Jan 2012 07:37:01 -0500

I am experimenting with multi-GPU OpenGL rendering on Windows 7.
For now, I am using a pair of Geforce GTX 580 graphics cards in one PC, with two LCD displays (one per graphics card). I disable SLI in order to have access to the two graphics cards.

I try to have one process creating two OpenGL windows (one per graphics card). It works, but whatever I do, I don't get the performance benefits of the second card: all OpenGL calls are being sent (and processed) by the same graphics card.

This limitation is also confirmed by the team at http://www.equalizergraphics.com/.

Does anyone know if this limitation is "by design" from nVidia?
Or can we expect a future driver to solve that issue?

Thanks,

John.

I currently have an FPGA-based PCIe system that I would like to accelerate with GPUs for floating point calculations. I peer-to-peer between my FPGA PCIe devices, and was wondering if I would be able to peer-to-peer from one of my FPGA PCIe devices to a GPU? Thanks in advance for any information!

opencl for 64-bit linux?

Cookie Monster — Tue, 20 Mar 2012 19:17:34 -0400

I've installed the 295.20 64-bit linux drivers (with a 8600 GTX card). For the life of me, I can't seem to find the libopencl.so library. The driver package installed the libcuda.so and (of course) for libGL.so libraries though. Is opencl supported in the 295.20 drivers? I've also installed the cuda tool kit and SDK packages.

A problem with setting up a CUDA card in Windows

Echilon — Fri, 16 Mar 2012 23:21:19 -0400

I have recently become interested in CUDA programming, and decided that I would like to work on it on my desktop. I have originally invested in AMD graphics cards mainly for playing games. Now I have also invested in a GTX 560Ti for CUDA programming.

I am currently developing on Windows, and my predicament is that Windows does not recognize the GTX 560Ti. Originally, when I first put in the GTX 560Ti, Windows recognized it, however a program I had installed on the desktop was complaining about my AMD driver, and so I went about fixing it(I had a few issues earlier with the specific graphics card I have and the drivers not playing well together). Once I had fixed the issue, I then turned my attention towards the GTX 560Ti.

I placed the GTX 560Ti in the original spot I placed it in and started up the machine. Once booted and logged in, I tried to install WHQL 296.10 and it told me that there was no NVIDIA hardware in the machine. I checked in Windows Device Manager, and sure enough, it did not list the GTX 560Ti. I forced the Device Manager to scan for changes in hardware, but to no avail. I then shut down the machine and tried reseating the card(and checking if I put it in the right slot) multiple times, without success. The question I have is, should I move the GTX 560Ti to the primary PCI-E x16 slot and install the driver, and then put in the original set up, or is there some clever way to get Windows to see that I have the GTX560Ti in the machine?

I still plan on using the AMD cards for my graphical heavy lifting and every day use.

OpenGL ES 1.x Vs OpenGL ES 2.0 and the GPU

ppuspu — Tue, 13 Mar 2012 01:52:18 -0400

Implementations of rendering a triangle are done in OpenGLES 1.1 and OpenGLES 2.0(with shaders).I am not bothered about the FPS. My question is do we need a Graphics card to run the 2 applications ? If not then what else is required ? Kindly guide to some good resources through which I can enhance my graphics knowledge from the Hardware point of view.

Thanks in advance.

Problems trying to compile/link Direct3D 10 SDK Smoke sample

HIDEBU — Tue, 15 Nov 2011 01:39:11 -0500

I've been trying to compile this sample (http://developer.download.nvidia.com/SDK/10/Samples/Smoke.zip) that's included with the set of samples from the Direct3D 10 SDK so that I can experiment with it, but I've been having a lot of trouble trying to make it work. I have installed the Direct3D 10 SDK, Cg 3.0, Microsoft DirectX SDK (February 2010), and am attempting to compile the sample on Visual Studio 2008. I've encountered a number of issues so far which I've documented below, but I'm stuck on how to fix a linker error with the .lib file nvutd.lib. Any help would be very much appreciated!

Problem 1: FXC custom build step fails as "'fxc.exe' is not recognized as an internal or external command.
- FXC.rules file modified to include the path where the x86 FXC executable is, in particular:
CommandLine=""$(DXSDK_DIR)Utilities\bin\x86\fxc.exe" [output] [target] [strict] [compat] [perf] [noopt] [nopre] [child] [Inputs]"

Problem 2: Voxelizer.fx(281,19): error X4580: emitting a system-interpreted value which is not written in every execution path of the shader
- Fixed by forcing default values onto the GsGenVelOutput object before Appending it to the TriangeStream object.

Problem 3:smoke\direct3d\include\dxut\core\dxut.h(93) : fatal error C1083: Cannot open include file: 'd3dx9.h': No such file or directory
- Fixed by adding "$(DXSDK_DIR)\Include;" to the Additional Include Directories of the project.

Problem 4: 1>LINK : fatal error LNK1104: cannot open file 'dxerr9.lib'
- dxerr9.lib doesn't exist anymore; it's been deprecated and replaced with dxerr.lib (see: http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=23549). Change the reference to it in the Linker accordingly.

Problem 5: DirectX library files still not found
- Fixed by adding "$(DXSDK_DIR)\Lib\x86;" to the additional library directories of the Linker.

Problem 6: 1>nvutd.lib(nvutmedia.obj) : error LNK2001: unresolved external symbol "unsigned int (__stdcall* ATL::g_pfnGetThreadACP)(void)" (?g_pfnGetThreadACP@ATL@@3P6GIXZA)
- I don't know what the correct resolution to this problem is.
Adding the line "#include " to the precompiled header file Smoke.h results in a big stream of errors from the project's fcollada\futils\fuerror.h. If I add the file atls.lib and the path "C:\Program Files (x86)\Microsoft Visual Studio 8\VC\atlmfc\lib" (which is where atls.lib is located) to the Linker, I get link errors with various DXUT obj files, all claiming that "LNK4099: PDB 'vc80.pdb' was not found", followed by the linker crashing out.

Multi Vendor CGFX Profiles OpenGL

-Raven- — Mon, 05 Mar 2012 09:44:48 -0500

Hello there,
I was wondering if there is any way to use more recent *lol* features like the tex2DArray which requires at least the gp4fp profile on a multi vendor profile like glslf. Apparently the glsf profile has the "version=x" that says

version=val
GLSL version to target. Supported versions are 100, 110, 120, 130, 140, 150, 330, 400 and 410.

but even when setting that on >= 330 the FX-Composer won't compile it, probably given the fact that is only supports glsl up to 120 ???

I am currently on a project that is forced on an old engine and on OpenGL and I hate to be forced some fancy alternative methods on non-NVIDIA GPUs. While I do understand that NVIDIA will only focus on NVIDIA cards, the lack of multi-vendor support on the OpenGL-side of CGFX is really a devastating downside :-( Any help would be appreciated - and no I don't want to use 3D Textures instead of texture arrays.

Several Cards on one motherboard (not in SLI) problem

ugahugo — Fri, 02 Mar 2012 09:38:14 -0500

Hey guys!

I have MSI Big Bang Marshal 3 and GT430 and GT560 and one monitor connection (on GT560).

The problem is that my motherboard can't see GT430 when GT560 is working. When I install just GT430 and connect it to my monitor - video card is working, all is okay. But when 2 cards have installed only GT560 can output a signal to monitor (and can be defined in OS).

I think that I need to install something like hardware stub to GT430 port. Am I right?

OS is WinServer2008R2x64.

Please help.

Technical problem with latest Nvidia graphic drivers and DirectX9

ccw — Thu, 01 Mar 2012 16:03:12 -0500

It would appear that the latest Nvidia graphic drivers are hooking the D3D9.DLL function 'Direct3DCreate9' in such a way that any previous hooks are overwritten.

The previous hook in my test case was applied using Microsoft Corporation Detours (Version 1.5 Build 46) during a DllMain() DLL_PROCESS_ATTACH of a dll injected into another process. If the test hook is applied later it does not get overwritten.

Typecasting to custom struct in kernel

avion85 — Sun, 26 Feb 2012 17:17:30 -0500

Since this is my first post, greetings to everyone.

I've encountered a problem regarding casting to a custom struct in a kernel, hopefully someone else was in the same situation.

I'm passing as a parameter into a kernel from a .cu file a large array which I would like to cast into a struct and access as an array of structures.

pseudo-code:

kernels.cu (with nvcc)


struct myMatrix
{
	float e[6];
};
__global__ myKernel(float *raw, myMatrix *p){
 myID = int me_idx = blockIdx.x * blockDim.x + threadIdx.x;

 myMatrix m = p[myID];	  //does not work - "???" in nsight for all values 

 myMatrix n =((myMatrix *)raw)[myID];     //does not work also - "???"

 float a = raw[0];    //works and I get correct single float values, but unstructured

 float 4 b = ((float4*)raw)[0];  //works and I get correct tuples

//what I want:
Matrix m = p[myID];
float something = m.e[3];
}

main.cu (with microsoft c compiler)


float *p = [large array];
myKernel<<>>(p,(myMatrix*)p);

I am using Parallel Nsight to inspect the values and what I get is "???" while stepping through the program. I have never had problems if I use the built-in types like float4. However, I would of course, like to have my own structures working properly.
Maybe the problem is in the alignment? If so, to which value to I align?

Appreciate the help.
Avion

PS.Working with Visual Studio, everything is 64bit.

EDIT: added another example that works.

Code runs on weak GT540M but not on fast GF 560Ti ??

StefanDS — Sun, 27 Nov 2011 07:46:51 -0500

Hi all,

I'm writing some OpenCL kernels to do stream compaction, which works fine on a Quadro FX 4600 (old powerful professional card) and an GT 540M (1-year old low-range laptop chipset). But when I try to run on a GTX 560 Ti (1-year old high/mid range desktop card), a clCreateFromGLTexture2D call returns CL_OUT_OF_RESOURCES.

How is this possible? The Quadro I could understand, I believe the drivers of professional cards manage resources differently, but the GTX 560 is in every way a better card then the GT540M, and they are both consumer cards. The 560 also has more recent drivers, I would expect it to run better, not worse.

Does anyone has an idea on what could cause this? I'll attach the output of oclDeviceQuery for both cards (except the imageformat stuff with is identical):

Developing Windows applications for the Tesla GPU

paysonwelch — Fri, 10 Feb 2012 06:51:21 -0500

Greetings I have a very quick question. I am a Windows application developer who needs to crunch lots of data. Can anyone tell me if it is relatively easy to write code that can be offloaded to a Tesla GPU using Visual Studio?

Specifically my application has a GUI front-end, at the very least is it possible to compile a C++ library that can be included without much hassle?

Also any tips or suggestions for research would be greatly appreciated. Thanks in advance.

Upgrading an S870

paysonwelch — Sat, 11 Feb 2012 18:50:29 -0500

I'm looking at an S870 1U rackmount enclosure with 4xC870 GPU cards. I am wondering if it is possible to swap out the C870 cards for something with a little more punch. Does anyone know if this is possible? E.g. if I replace the C870 cards will the S870 accept new ones and continue to function properly?

CUDA Toolkit 4.1.15 on openSUSE 12.1?

gue22 — Wed, 18 Jan 2012 15:55:04 -0500

Went to great lengths to install openSUSE 12.1 on a physical machine (as opposed to the VMware and Hyper-V VMs I normally use to try all kinds of things) only to find out upon closer inspection that the CUDA Toolkit 4.1.15 downloads are targeted for 11.2.

Any chance for success on 12.1 (quite different core from 11.x) or should I set up Yet Another variant with 11.2?
Thx

FX Composer video card compatability

shenjoku — Wed, 01 Feb 2012 15:16:31 -0500

Is there a website listing or something of which graphics cards are supported by FX Composer? I can't get a single Cg FX file to compile. Everything fails saying it can't validate the technique, but I can run the Cg version of the shaders I've written in our application just fine.

I have an ATI Radeon HD 3870 card, and, from what I've read, that might be the problem but I just want to confirm.

Need a driver update for GeForce 330M

twist69 — Sun, 29 Jan 2012 16:41:39 -0500

My notebook is AcerAspire5745G-434G64Mn
My OS is Windows 7 Ultimate x64
My video card is GeForce 330M (HW ID is PCI\VEN_10DE&DEV_0A29&SUBSYS_035B1025&REV_A2
)

I need a driver update, because some games and apps need latest drivers, but when I download 330M drivers from nVidia, they is not compatible with my video card.
Sometimes video drivers crash, but now I can't give info for this problem. I think when you do latest version of drivers compatible with my card, it will be fix.

Help me please!

NVIDIA driver problem in openSUSE, System performance has been slow but

firefox scrolling now is slower than before, also when i start firefox, system freeze for about 5 seconds also when i try to exit system from screen saver it freezes for some seconds.
but in the other hand i tested a game that was slow before installing nvidia driver and i saw that after installing NVIDIA driver it is faster than before and run better. these results are opposition.

[B]i attached 2 files:[/B]

1- "nvidia-bug-report.sh" result
2- "man nv" result

[B]also the result of "cat /etc/SuSE-release" is below:[/B]

[CODE]# cat /etc/SuSE-release

also i should add that i used "nomodset kernel parameter on boot", and "uninstalled nouveau driver" and change "NO_KMS_IN_INITRD" to yes.

please help me,

Issues w/ Android Tegra Ventana Port

herriojr — Tue, 24 Jan 2012 13:42:43 -0500

Hi All,

I appear to be having a few issues with the Tegra Ventana with the stock firmware (3.2).

1) ConnectivityManager does not properly report the ActiveNetworkInfo, and instead returns null even though a wifi connection does exist.

2) GPS does not work at all, a connection is never established. Has anyone verified this working? I'm trying to figure out whether this one is a hardware or software issue.

3) There appears to be a slot for an SD Card, but I don't know if it really supports a mobile connection, and trying to set the APN with an SD Card in fails. I'm assuming this is just not supported?

3) The latest Android at http://nv-tegra.nvidia.com/gitweb/ doesn't appear to be the most up to date, is there another location for the 3.2 source?

Thanks in advance!

Unable to model a tire with physX primitives using compound shapes

FallBack — Wed, 11 Jan 2012 14:33:37 -0500

Out of the basic physX primitives for building compound shapes: Box, Capsules, Spheres, and Planes. It seems impossible to create a tire object that can roll like a tire and stack up on it's side w/o using a convex mesh which are more expensive. Any sphere or capsule used for the round part of a tire would extend too far on its sides, making it pretty much a full sphere.

Is there a way to take a sphere and instead of compounding a cuboid to it, cut a cuboid out from it? If two boxes were cut out from a sphere in such a way that it left flat sides on the left and right and allowed it to stay round on all of the other sides.

Using PAL (Physics Abstraction Layer) with PhysX

venteras — Tue, 08 Nov 2011 02:33:33 -0500

Does anyone use PAL together with PhysX? What is your opinion of using PAL with PhysX?

We are using PhysX in our 3D application, but also use Bullet for non-realtime simulations (tri-mesh to tri-mesh collisions) and we are contemplating if it is a good idea to make use of PAL? I've only recently come to know of it, and I can see the definite advantages of using it, but also dont want to be limited by it.

What is your opinion of it?

Regards
AV

V4L Driver

userAAA — Thu, 03 Nov 2011 00:26:33 -0400

Hi everyone,
I would like to modify existing v4l2 driver (tegra_v4l2_camera). I want it to work with RGB or RAW cameras too. I saw some register set in driver. It was written by some values, which was defined like "xxxxxx_FMT_UYVY". I assume, there could be some constants like xxxx_FMT_RGB.
Do anybody knows about it?
I know many products with tegra2 with video camera. Are they all using only YUV camera???
PS: i can't change my camera.

Very Slow Opengl Performance with Geforce 580/590 gtx

hanno hugenberg — Fri, 07 Oct 2011 05:41:26 -0400

Hi all,

We ran into some (for us) un-explainable performance issues with our new Zotac geforce 580 gtx and Zotac geforce 590 gtx cards.

The Software we use is our own development and based on OpenSG 1.8 ( uses Opengl 2.1 as far as i know).
Testing Hardware operates with Windows 7 and XP, both 64 bit.
Driver was the latest: 280.26

We got a Scene with around 800 Scenegraph Nodes and 4 Million Triangles.

Resulting FPS (Identical View and Resolution):

Geforce 8800: 11
Quadro 5600: 22
Quadro 4600: 16
Geforce 580gtx: ~3,5 ?
Geforce 590gtx: ~3,5 ?

So, we only reach around 3,5 fps with the newest graphic cards? Its reproducable on different pcs with other zotac 580/590 geforce cards.

We tried a lot, thought about it for a week and have no conclusion.

Can you help? Any suggestions why we got this drop in frames?
We bought around 9 590 cards for our Cluster system to increase the frames, and not only the electric power consumption :P

What can it be? Driver issues? Bad Ram, incompatible mainboard, Downwards-incompability with lower OpenGL versions?

Thank you very much in advance for your thoughts an time.

3D Vision logo/compatibility/licensing

DigiMagic — Thu, 20 Oct 2011 06:39:10 -0400

Hello,

I've been instructed by Nvidia's online tech support to post my question here.

I work for a small company that plans to produce a video processing device, especially suited for dual polarized and dual spectrum division projection systems. We have a functional demo that works with full HD 3D video over HDMI 1.4a.

If we would like to make our device compatible with Nvidia's 3D Vision system, I am interested what are the requirements (beside obvious technical ones like dual-link DVI connection)? Is there some list of compatibility requirements or tests? It might not make sense at the first sight, since we would be actually assisting Nvidia to sell more of their products, but would we be required to pay any licensing fees?

Thanks in advance for all replies.

Using boost fusion/mpl in a cuda kernel

nojiky — Wed, 19 Oct 2011 08:20:26 -0400

Hello guys,

has anybody out there an idea how to use fusion and mpl in a kernel? I began putting __host__ __device__ in front of each boost function, but this seems to be a never ending job.

First I replaced each "inline" by "__host__ __device__ inline" and each "static" by "__host__ __device__ static" (with sed) and I think I made 90% of all functions cuda ready but for the rest it's still too much doing it manually.

Any hint would be great.
