I’m tring to understand how PGDBG works because I have a bug in my MPI code written in Fortran 95. Actually my speciality it’snot at all in programation but now i see myself obliged to use it.
To be short, I have this error message:
*** An error occurred in MPI_Isend
*** on communicator MPI COMMUNICATOR 4 SPLIT FROM 0
*** MPI_ERR_RANK: invalid rank
*** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)
Does somebody has an ideea about what coudl it be?
Thanks in advance for your help.
