Seeing the following compiler warnings with nvidia hpc sdk 22.2 available here https://developer.nvidia.com/nvidia-hpc-sdk-releases

Background information

What version of Open MPI are you using? (e.g., v3.0.5, v4.0.2, git branch name and hash, etc.)

v4.1.3

I tried to compile the released 4.1.4 with nvcc and nvfortran 22.04 and the compilation failed.

I had to change the configure of the openmpi library as below, i.e. I did add nvfortran so that the compiler is recognised. After that it worked. This is probably more related to issue #8919

Without I got the error relocation R_X86_64_32S against .rodata' can not be used when making a shared object; recompile with -fPIC

@Akshay-Venkatesh @janjust Can you guys comment on this?

sangallidavide commented 2 years ago

I have the same problem reported above about libevent with nvidia compiler. If the configure does not find the external libevent, the compilation of the internal libevent fails.

On ubuntu the solution is to install libevent-dev After that the installation works fine with the above change to the configure

I have seen similar warnings with AOCC 4.2
