[MPICH] Problem with MPICH2 and Opt++

[Brett Gordon]

Hello,

I am trying to get OPT++, a numerical library, working with MPICH2 but
I'm running into some problems. I can't figure out if the problem is
with OPT++, perhaps in terms of their parallel implementations, or
with the way I have MPICH2 configured.

When running the 'make checks' on OPT++, I get several fails, one of
which looks like this:

/bin/sh: line 1: 10141 Segmentation fault      ${dir}$tst
FAIL: tstfdnewtpds
Signal:11 info.si_errno:0(Success) si_code:1(SEGV_MAPERR)
Failing at addr:0x44000098
[0] func:/usr/local/lib/libopal.so.0 [0x2aaaab440bb8]
[1] func:/lib64/tls/libpthread.so.0 [0x2aaaab9f62c0]
[2] func:/usr/local/lib/libmpi.so.0(PMPI_Comm_rank+0x4a) [0x2aaaab18cd1a]
[3] func:./tstnewtpds(main+0x4f) [0x41ac4f]
[4] func:/lib64/tls/libc.so.6(__libc_start_main+0xda) [0x2aaaabb1b5aa]
[5] func:./tstnewtpds(__gxx_personality_v0+0x7a) [0x41aaea]


I know that libopal is not the source of the error. I have recompiled
the program and inserted a number of print statements, which confirm
that the error occurs at [2]. The code around the MPI_Comm_rank
statement is simple enough:

int main (int argc, char* argv[]){
  int me = -1;
  MPI_Init(&argc, &argv);
  MPI_Comm_rank(MPI_COMM_WORLD, &me);

  .....
}

This looks standard way, so I'm not sure where to proceed. I have no
experience with MPI-related programming. Does anyone have any
suggestions? Does this look like a problem with my configuration of
MPI or is it within OPT++? If more information is needed, please let
me know.
