BLACS 64bit compiling
It is theoretically impossible to compile BLACS to make it work in 64 bit computing environment. BLACS package downloadable from www.netlib.org works only on 32 bit OSs. Otherwise, all the libraries including BLAS, LAPACK, and SCALAPACK should be recomiled with 32 bit option. A possible way to go around this bottleneck is to use Intel MKL library, specifically,
The latest version of openmpi-1.2.8 works well with Intel-BLACS and scalapack compiled using Intel FORTRAN compiler, ifort.
