Shown below is a sample makefile that demonstrates the path and usage of the libraries :

The MPI trace library
BLAS – Basic Linear Algebra Subroutines
LAPACK (also requires BLAS lib)
BLACS ( communication module required for ScaLAPACK)
ScaLAPACK ( requires BLAS, LAPACK, and BLACS)

This ScaLAPACK is built from the source download from www.netlib.org. The makefile (not shown) used to build ScaLAPACK is modified from make.sp2. Please feel free to use the built package at its current location. Email Kadin Tseng (kadin@bu.edu) or call him at 617-353-8294 if you need help.
