[MPICH2-dev] Error creating custom MPI Type struct

[Shankar, Shashank (US - New York)]

Hello,

Thanks to John Vert, for answering my previous question!

I am trying to develop a distributed application utilizing MPI as the
communication mechanism, and have run into an error while creating a
custom MPI Type struct for data transfer between MPI processes. A
snippet from the mpiexec output is as:

============
job aborted:
rank: node: exit code[: error message]
0: socw3s4ap01.solnet.com: 13
1: socw3s4ap01.solnet.com: 13: Fatal error in MPI_Type_struct: Invalid
datatype, error stack:
MPI_Type_struct(191): MPI_Type_struct(count=365, blocklens=0x0012EDAC,
indices=0x0012E244,
 old_types=0x0012E7F8, new_type_p=0x0046C854) failed
MPI_Type_struct(130): Invalid datatype
============

Any help or suggestions in this regards will be very appreciated.

Thanks!
