Error using mpiexex (or mpirun)

Hi all,

I am getting a run-time error using the openMPI library included in the 26.3 NVIDIA HPC SDK.

My system reports the following versions on the compiler and library:

$ nvc --version

nvc 26.3-0 64-bit target on x86-64 Linux -tp haswell
NVIDIA Compilers and Tools

$ mpicc --version

nvc 26.3-0 64-bit target on x86-64 Linux -tp haswell

$ mpiexec --version
mpiexec (OpenRTE) 4.1.9a1

Below is a copy of the error I am getting:

Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.


mpiexec detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

Process name: [[59678,1],1]
Exit code: 127

Before installing the 26.3 NVIDIA HPC SDK I was using the 25.7 NVIDIA HPC SDK without any problem.

Any idea?

I really appreciate any help you can provide.

Thanks.

I suggest you post your question on the sub-forum for HPC SDK questions here. I can move it there if you like.

Thanks.

I just re-post it there.
