Hello.
Can you tell me how cuda runtime chooses GPU device if 2 or more host threads use cuda runtime?
does the runtime choose separate GPU devices for each thread?
does GPU device needs to be set explicitly?
Thanks

When writing CUDA applications, you can either work at the driver level or at the runtime level as illustrated on this image (The libraries are CUFFT and CUBLAS for advanced math):
I assume the tradeoff between the two are increased performance for the low-evel API but at the cost of increased…

I have a VS2010 project that was tested with CUDA 4.0, today I installed CUDA 4.2 and I want to update this project, the problem is that when I try to run the project it asks me for cudart32_40_17.dll, but since this is CUDA 4.2 I only have on my folders (C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4…

I use ubuntu 12.04 64 bits with GTX560Ti.
I install CUDA by following instruction:

I'm currently using CUDA.NET library by GASS.
I need to initialize cuda arrays (actually cublas vectors, but it doesn't matters) in one CPU thread and use them in other CPU thread. But CUDA context which holding all initialized arrays and loaded functions, can be attached to only one CPU thread.
There…

My company has a setup of two GTX 295, so a total of 4 GPUs in a server, and we have several servers.
We GPU 1 specifically was slow, in comparison to GPU 0, 2 and 3 so I wrote a little speed test to help find the cause of the problem.
//#include <stdio.h>
//#include <stdlib.h>
//#include…

Are there currently any programs available for monitoring/measuring GPU temperature? Something preferably free, and for either Windows XP and Windows 7.
Thanks in advance!

Hi,
let's say that I am a physicist and that I am the master of the universe when it comes to port salready existing oftware to GPU's with 100x or more speedups. Let's say that I find that some other scientist, which does not know how to program GPU, publishes the Open Source code in his/her website…
