I have some question concerning difference of PGI compiler and Intel compiler

I tried to change PGI compiler to Intel compiler with test.

But I have some problem. The problems are observed at MPI communication. Main error message is followings.

p4_error: interrupt SIGSEGV: 11

This error is occurred including the subroutine. But this subroutine operates at PGI compiler

But this program doesn't operate including this subroutine.

Help me

Thank you

Perhaps you are linking the Intel-compiled program to a PGI-compiled MPI library. You cannot mix Fortran binaries. The MPI library also must be compiled by Intel Fortran.
