Is Intel MPI GPU Aware with DPCPP?

[GouthamKK]

Hello Team,

I have a couple of questions regarding Intel MPI and performance analysis tools.

1. I was going through Intel MPI documentation about GPU support and I am just curious to know whether Intel MPI is GPU Aware (DPCPP).? If yes, where I can read more about the same?

2. Can I use Intel oneAPI DPCPP code with Intel MPI together? If yes, how can I achieve that?

3. If the answer to the above questions is yes then - Is there any performance analysis tool that I can use to analyze the code (both MPI level and DPCPP code level in the same tool)? Do that existing tools like ITAC and Application Performance Screenshot record those details (Both MPI and DPCPP)?

Thanks in advance

Hi Goutham,

Thanks for posting in Intel Forums.

Intel MPI is GPU aware with DPCPP.

>>"Can I use Intel oneAPI DPCPP code with Intel MPI together? If yes, how can I achieve that?"

Yes, you can use Intel oneAPI DPCPP code with Intel MPI together. Please refer to the below link to know how to compile and run MPI programs using DPC++:

Yes, you can use Intel Vtune Profiler tool. Please refer to the below links:
