[mpich-discuss] Trouble with PARPACK

[Boucher, Christopher R]

 Hello, I've been trying to build PARPACK using MPICH2 and MinGW. Currently my program, which uses several PARPACK routines, compiles and executes properly; however, when I try to run with four or more processes I get the following error:

(Using 4 processes)

Fatal error in MPI_Bcast: Other MPI error, error stack:
MPI_Bcast(786)............................: MPI_Bcast(buf=011F9260, count=2, MPI_DOUBLE, root=0, MPI_COMM_WORLD) failed

MPIC_Recv(81).............................:
MPIC_Wait(270)............................:
MPIDI_CH3i_Progress_wait(215).............: an error occurred while handling an event returned by MPIDU_Sock_Wait()

This error involving MPI_Bcast repeats itself three more times. The error appears to occur when my program calls the PARPACK routine "pznaupd".
If anyone has experience with PARPACK, or has an idea of what may be causing this error, please let me know. Thank you!

Sincerely,
Christopher Boucher
