Simple mpirun example SEGFAULTs using intel/oneapi-hpckit:2022.1.1-devel-ubuntu18.04

[EugeneW403]

I'm trying to run a simple Hello World MPI example inside the Docker container image and getting a SEGFAULT.

I'm using Docker container image:

intel/oneapi-hpckit:2022.1.1-devel-ubuntu18.04

https://hub.docker.com/r/intel/oneapi-hpckit

$> docker run -it --rm intel/oneapi-hpckit:2022.1.1-devel-ubuntu18.04

root@c1ea2a0c8961:/# cat <<EOF >hello.c

#include <mpi.h>

#include <stdio.h>

int main(int argc, char** argv) {

    // Initialize the MPI environment

    MPI_Init(NULL, NULL);

    // Get the number of processes

    int world_size;

    MPI_Comm_size(MPI_COMM_WORLD, &world_size);

    // Get the rank of the process

    int world_rank;

    MPI_Comm_rank(MPI_COMM_WORLD, &world_rank);

    // Get the name of the processor

    char processor_name[MPI_MAX_PROCESSOR_NAME];

    int name_len;

    MPI_Get_processor_name(processor_name, &name_len);

    // Print off a hello world message

    printf("Hello world from processor %s, rank %d out of %d processors\n",

           processor_name, world_rank, world_size);

    // Finalize the MPI environment.

    MPI_Finalize();

}

I was able to resolve this by setting I_MPI_FABRICS=shm and launching the container with increased shared memory:

docker run --shm-size=512m ...

Thank you!
