I am running CentOS 5.5 with one device installed (GTX 580)
I am spawning some pthreads that I am trying to each get working in the same context. However, when I run the following code in my worker threads, I get a different value than in the main thread
cudaError er = cudaSetDevice(0); CUcontext localctx; cuCtxGetCurrent(&localctx);
I was under the impression thati n CUDA 4, setting a device in a worker thread gave it the same context as the host thread?
Further, using cudaSetDevice() in my worker thread, and then trying to check the memory availability:
size_t freeMem, total;
returns zero for bothe free and total. What am I doing wrong?
