Thank you all. THe reason that it came up is that I want to run both RTX 2060 Super FE and Quadro P4000 in same system. Why do I want to do that? Well I already have the boards. Each one sits in its own system. I am experiencing some OpenCL compatibility issues in some applications. My tool set is core around three packages. Maya '19, Houdini 17.5, and Realflow 10 & 20. Specifically the use of OPenCL and CUDA for GPU running of FLIP and FLuid-PDB dynamics. OpenGL performance is, of course, fantastic for both my RTX and Quadro boards. My secondary hobby need is high DX11/DX 12 game performance for flight simulation software. DCS, X-Plane, and Prepare3D. RTX 2060S is completely superior to Quadro P4000 in flightsims. My average FPS at 2560X1440 @144Hz is above 120 and gets up to 190’s. Easily doubling the FPS under Quadro P4000.
Where I am having issues is OpenCL usage. Maya 2019 OpenCL and ArnoldGPU(Beta) is very unstable under RTX 2060S. ArnoldGPU crashes every time in GPU only mode, and drops to CPU mode, or crashes Maya. As it is Beta, I am not that concerned about it just yet. Maya’s dynamics OpenCL usage, when it available, works OK in both RTX and Quadro Pascal, but a lot more stable and available under Quadro Pascal. Houdini is same way, but I am not certain exactly how Houdini’s dynamics engine uses OpenCL. I enable it in solver option, and it runs. I notice that GPU and CPU are loaded at same time. But it is inconsistent, as some OpenCL sims load GPU , while others favor CPU. I am using production 17.5.360 build. Realflow OpenCL is a real problem. It works under Quadro accelerating FLIP, and CUDA works great accelerating Realflow’s PDB solvers. But RTX’s OpenCL is unavailable in RF10 and new RF20. Option is greyed out under FLIPs, but CUDA is available, but not as fast (in RF) as Quadro. Both RTX 2060S and Q P4000 have 8gb. So I want to have both of them running at same time on same system, instead of having two systems.
Cheers
