trying to run a fortran MPMD with barrier synchronisation :

here the master prog:

******* MASTER ********
      program MASTER

[...]
C ENROLL IN PVM

      CALL pvmfMYTID(
     O               MYTID)
      CALL pvmfJOINGROUP(
     I              'GROUP',
     O              INUM)
      PRINT*,'TID:',MYTID,' JOIN GROUP <GROUP> AS MEMBER #',INUM

C SPAWN SLAVE.EXE TO NPROCS SLAVES

      PRINT*,'NPROC=',NPROC

      CALL pvmfSPAWN(
     I              'slave.exe',
     I              PVMTASKDEBUG,'*',NPROC,
     O              TIDS,NUMT)
C
[...]
**********************



and there the slave prog:

******* SLAVE ********
      program SLAVE

[...]
      CALL pvmfMYTID(
     O               TID1)
      CALL pvmfJOINGROUP(
     I              'GROUP',
     O              INUM)
      PRINT*,'TID:',TID1,' JOIN GROUP <GROUP> AS MEMBER #',INUM

[...]
**********************



the master prog join the group successfully, but not the slave :
the slave program wait for "don't know why" at the pvmfJOINGROUP call

any suggestions, please ??

I MUST have a Multi Program application
