I’m new to using CUDA and I’m having some trouble getting it running on my ROCKS 6.2 cluster.
I currently have 4 nodes in the cluster, each with a single GTX745.
When I run ‘run_linpack’ with mpiexec -np 4, I get the following error:
!!! ERROR: Not enough GPUs on node compute-0-0.local, 1 GPUs found, 4 GPUs required !!!
How can I configure the CUDA HPL to run using a single card on each PC? Am I using an incorrect version of HPL for my configuration?
