Dear all, I am developing a code for hydrological applications. It is written in FORTRAN and I am using ifort combine with openMPI.
In this moment, I am debugging my code due to the fact that I have some NaN errors. As a consequence, I have introduce in my Makefile some flags for the ifort compiler. In particular: -c -r8 -align *-CB -traceback -check all -check uninit -ftrapuv -debug all* -fpp However, this produce some unexpected errors/warning with mpirun. This is the error\warning: Image PC Routine Line Source MPIHyperStrem 00000000005AA3F0 Unknown Unknown Unknown MPIHyperStrem 0000000000591A5C mod_lathyp_mp_lat 219 LATHYP.f90 MPIHyperStrem 00000000005A0C2A mod_optimizer_mp_ 279 OPTIMIZER.f90 MPIHyperStrem 00000000005986F2 mod_optimizer_mp_ 34 OPTIMIZER.f90 MPIHyperStrem 00000000005A1F84 MAIN__ 114 MAIN.f90 MPIHyperStrem 000000000040A46E Unknown Unknown Unknown libc-2.23.so 00007FEA758B8830 __libc_start_main Unknown Unknown MPIHyperStrem 000000000040A369 Unknown Unknown Unknown forrtl: warning (406): fort: (1): In call to SHUFFLE, an array temporary was created for argument #1 My questions is: It is possible to use ifort debugging flags with openMPI? thanks a lot Diego
