we must use this flags for openmpi else some tests will just hang.
I have done some more tests only with mvapich2 0.9.8 and build
BLACS/SCALAPACK without any optimization (-O0 -g) for gcc version 3.4.6
and 4.1.1. For fortran gfortran 4.1.1 is used
I can run all tests with gcc version 3.4.6 ;-)
With gcc version 4.1.1: 2 tests do not finish:
1) xzgsep
2) xzllt
We want to use MVAPICH2 so i did not test MVAPICH1 today,
Regards
