[mvapich-discuss] Errors in BSBR when running xCbtest and xFbest of the BLACS

[Margulis, Claudio J]

To be more precise I compiled mvapich2-1.9 with gcc/gfortrtan 4.5.1 and I also compiled a second version with gcc/gfortran 4.7.0.  In both cases I got the same errors when running the test programs for the BLACS.

Subject: [mvapich-discuss] Errors in BSBR when running xCbtest and xFbest of    the BLACS

Hi, I was trying to use mvapich2-1.9 to compile an application that uses
scalapack and the BLACS. This is for the latest version of BLACS which
comes bundled with scalapack-2.0.2
I compiled mvapich2-1.9 against gcc/gfortran versions 4.5.1 and 4.7.0
successfully. The I compiled scalapack and BLACS successfully as well
against mvapich2.
When running the BLACS tests xCbtest and xFbtests I get errors for the
BSBR sections. All other sections pass the tests.

I did a quick search and found that my errors are identical to those
reported here:
http://fpmd.ucdavis.edu/qbox-list/viewtopic.php?p=290

I think I also downloaded the latest trunk version and performed the
same compilations and tests getting the same errors for the BLACS. Can
anyone shed light? No errors on compilation.

versions of BLACS compiled with openmpi and the same gcc compilers do
not have the same problem.

Thanks
Claudio
