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

[Claudio J. Margulis]

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
