I honestly don't remember the Forum's rationale for this; that's just the way 
it is.

Brian Barrett and I have a proposal up for to the Forum for making it 
permissible to call INIT multiple times, etc.  We proposed it and it was 
generally well-accepted; we got some good feedback, so we need to revise the 
proposal and present it at the next meeting in January.  I guarantee that 
nothing will happen with our proposal before SC.  :-)

[Durga Choudhury]

Any particular reason these calls don't nest? In some other HPC-like
paradigms (e.g. VSIPL) such calls are allowed to nest (i.e. only the
finalize() that matches the first init() will destroy allocated
resources.)

Just a curiosity question, doesn't really concern me in any particular way.

Best regards
Durga

Did you call MPI-INIT after you called MPI-finalize?  If so, you're not allowed 
to do that. Call. MPI-INIT once and call MPI-finalize once.

[amine mrabet]

messag

An error occurred in MPI_Init
*** after MPI was finalized
*** MPI_ERRORS_ARE_FATAL (goodbye)
[dellam:16806] Abort before MPI_INIT completed successfully; not able to
guarantee that all other processes were killed!
