hello:
After install parallel_studio_xe_2017.2.050, i try to test mpi like this:
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:
[ 8671.743574] test[1229]: segfault at 1 ip 00007ff2fdc59f45 sp 00007fff51885050 error 4 in libmpifort.so.12.0[7ff2fdb27000+17e000]
