[mpich-discuss] Fatal error in MPI_Init

[Jayesh Krishna]

Hi,
 Did you recompile your code with MPICH2 ? Which version of MPICH2 are you
using ? How are you launching your MPI job (the command used to launch
your job) ? Are you able to run non-MPI programs (Does "mpiexec -n 2
hostname" work ?)?
 
(PS: The error message)
Regards,
Jayesh

Dears sirs,

I got the following message when I tried to run my code under Windows XP:


Fatal error in MPI_Init: Other MPI error, error stack:
MPIR_Init_thread(394): Initialization failed
MPID_Init(90)........: channel initialization failed
MPID_Init(357).......: PMI_Init returned -1
[0] PMI_Init failed: FAIL - init called when another process has exited
without calling init

This software can be compiled against Linux (using Intel) and Windows
(using Open Watcom).
Under Linux, it works normally.
Under Windows, I got the message above.
SMPD seems to be ok once the distributed CPI program works normally.
If I link my code with MPICH1-1.2.6 and run with "mpirun", it also works
fine.

The weird thing is that I could already make it work with
MPICH2/Windows/Open Watcom.

Do you have any clue regarding the reason of this error?
What can I be doing wrong?

Thanks in advance,
LC
