I am trying to run a Simple CUDA program which queries the numbers of GPUs in the nodes usingOpen MPI v1.6.1 (64bit)inWindows 7 Professional 64bit Machines. When I run the application in root node, the correct GPU count is getting. But when the same application is tried to run in different nodes remotely usingOpen MPI, the GPU count is getting as0, ie, it is showing as No CUDA capable GPU is present in the node.
The root and the nodes havingCompute Capability 2.1 capable GPUs. I have built the code withCUDA 4.2. When a normal MPI application is running, it is working correctly.
Is there any special settings required for running a CUDA application in Windows 7usingOpen MPI v1.6.1?
