[Mvapich-discuss] osu-micro-benchmarks-7.5-1 error with NVIDIA

[Amit Ruhela]

Hi Dr. Panda,

I’m encountering the following errors while compiling OMB 7.5.1 with OpenMPI 5.0.8 and CUDA 13.0 on the Vista machine. I don’t think this issue is machine-specific, but it might be related to the latest CUDA version. Do you have any suggestions on how to resolve these errors?
