[mpich-discuss] Blocking MPI_Finalize

[Jayesh Krishna]

Hi,
 Can you provide us with more information on your problem ? Can you send us a test program (with source) that fails ?
 Also provide us more information on how you run your job (mpiexec parameters, node info etc).

Regards,
Jayesh

Subject: [mpich-discuss] Blocking MPI_Finalize

Hello,

My code (in C++ with Visual Studio 2010) uses the latest version of 
MPICH2, for domain decomposition. I try to execute it with 4 processes.

My problem happens when the processes call MPI_Finalize() : all 
processes seems to succeed, expect process with rank 0, which seems to 
be blocked.
It prevents other processes to terminate the execution successfully.

Remark : I've noticed that this problem happens especially when the 
domain i work on has an important size.

Can anyone help me ?  Thanks

Cécile
