Using the latest oneAPI HPC toolkit (beta 20200827) with Docker 2.4.0.0 on a Mac, when I try to run the attached simple MPI program on 2 processors I get these errors:
root@7794bb0f2839:/codes# mpiexec -n 2 ./a.out
===================================================================================
= BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
= RANK 0 PID 12395 RUNNING AT 7794bb0f2839
= KILLED BY SIGNAL: 7 (Bus error)
===================================================================================
===================================================================================
= BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
= RANK 1 PID 12396 RUNNING AT 7794bb0f2839
= KILLED BY SIGNAL: 7 (Bus error)
===================================================================================
Choosing any other number of processors works fine:
root@7794bb0f2839:/codes# mpiexec -n 3 ./a.out
RANK 2
SIZE 3
RANK 1
SIZE 3
RANK 0
SIZE 3
This was not happening with the previous beta, but I was also using the previous version of Docker (2.3).
