Prebuilt ScaLAPACK libraries are provided for a variety of architectures. http://www.netlib.org/scalapack/archives/index.html These ScaLAPACK archives contain all routines needed to run ScaLAPACK applications, with the exception of the BLAS and the BLACS libraries. Each library archive .a includes the (scalapack.a, pblas.a, redist.a, and tools.a) as built from the distribution tar file (scalapack.tar.gz). Note that each gzip tar file contains the library archive AND the SLmake.inc used to build the library. Details of compiler flags, etc. can be found in this make include file. Pre-built BLACS archives are available in http://www.netlib.org/blacs/archives/index.html If you do not have a BLAS library already available, a reference implementation may be obtained from: http://www.netlib.org/blas/blas.shar Questions/comments should be directed to scalapack@cs.utk.edu.
