in dir  "/opt/intel/compilers_and_libraries_2017.2.174/linux/mpi/test"      

use cmd :  "mpiicc test.c -o test "

then :"mpirun -n 2 ./test "

but, segfault  hanppend:

Hi Wang,

There are two duplicated threads in the forum, I have closed another one so we can focus on this thread. Thanks.

Could you please provide the the outputs of:

1. env | grep I_MPI

2. export -genv I_MPI_DEBUG=100 -n 2 ...

Thank you.

Regards,
