RC5-72 form distributed.net on fedora core 10 Decryption using cuda

Accelerated Computing CUDA CUDA Programming and Performance
1

Hi all,

I’ve just installed a fresh release of Fedora Core 10 for x86_64.

I’ve installed last cuda driver and sdk.

When I try to launch dnetc, it downloads datas but, just after that,
it tells me that an error occured and that the device is already in use…
It tells CUDA: ERROR too.

I’ve tried it into “init 3” mode and it’s the same way.

Drivers are for fedora 9 but the ones for version 10 are not available, afaik.

Has anyone tried to run dnetc for x86_64 under fedora 10 ?

(My machine : a64 x2 4200+/9800gtx+ and 2GB ram)

Thanks for your answers

Hello,

Well, finally, after all elements,I installed “Cuda Toolkit for fedora 8” and it runs.
I get [387,143,260 keys/s] (max) on a 9800gtx+, driver 180.06 for linux64 under Fedora 10 x86_64
on an A64 x2 4200+ with 2GB ram.

It frequently checks buffers.

PC under xp gives approx 20 Mkeys, PS3 under Yellow Dog 6 gives approx 180 and here,
it’s rating near 350 Mkeys.

Have good days

I seem to have the same issue with Ubuntu 8.04 and the 180.60 drivers.

I already installed the driver and toolkit but didn’t seem to help.
Any suggestions would be nice!

Hello,

Firstly, I installed 180.06 driver for linux 64 from Nvidia/cuda,

Secondly, I installed the “toolkit for fedora 9”.

Thirdly I installed another file but I haven’t got my machine at the moment,

I will tell you its name (Nvidia-rel *****).

Fourthly, I installed the SDK for fedora 9.

And, finally, yesterday, I installed the “toolkit for fedora 8”

and all is working right.

I didn’t see the toolkit for fedora 9 yesterday but it’s available now so,

I will give it a try this evening.

Have you followed this sequence ? Are you under 32 or 64 bits os ?
