Dear support,
I am trying to run a test case of AZTEC library named 
az_tutorial_with_MPI.f . The example uses gfortran + MPI. The
compilation and linkage stage goes O.K., generating an executable 
'sample'. But when I try to run sample (on 1 or more
processors) the run crushes immediately.

The compilation and linkage stage is done as follows:

gfortran -O  -I/shared/include -I/shared/include/openmpi/ompi/mpi/cxx 
-I../lib -DMAX_MEM_SIZE=16731136
-DCOMM_BUFF_SIZE=200000 -DMAX_CHUNK_SIZE=200000  -c -o 
az_tutorial_with_MPI.o az_tutorial_with_MPI.f
gfortran az_tutorial_with_MPI.o -O -L../lib -laztec  -lm -L/shared/lib 
-lgfortran -lmpi -lmpi_f77 -o sample

The run:
/shared/home/gordon/Aztec_lib.dir/app>mpirun -np 1 sample

Let me just mention that the C+MPI test case of the AZTEC library 
'az_tutorial.c' runs with no problem.
Also, az_tutorial_with_MPI.f runs O.K. on my 32bit LINUX cluster running 
gcc,g77 and MPICH, and on my SGI 16 processors
Ithanium 64 bit machine.

Thank you for your help,

Sincerely,
Rachel
