Sorry for the delay in replying -- we've been quite busy trying to
get OMPI v1.2 out the door!
Are you sure that you build BLACS properly with Open MPI? Check this
FAQ item:
http://www.open-mpi.org/faq/?category=mpi-apps#blacs
In particular, note that there are items in Bmake.inc that you need
to set properly or BLACS won't work properly with Open MPI.

Hello all,
I built BLACS on Itanium using Intel compilers under linux
(2.6.9-34.EL). But it fails default BLACS Fortran tests (xFbtest),
C tests (xCbtest) are ok. I’ve tried different configurations
combining OpenMPI-1.1.2 or OpenMPI-1.1.4, ICC 9.1.038 or ICC
8.1.38, IFORT 9.1.33 or IFORT 8.1.34, but all results were the
same. OpenMPI is built using 9.1 compilers. Also I’ve tried the
same using em64t compiler on Intel XEON – all tests were passed.
MPICH2 on IPF also works fine.
Is that an OpenMPI bug? Maybe some workaround exists?
Bmake.inc is attached.
Below is output I’ve got (Don’t pay attention to blacs warnings,
they are normal for MPI):
