ScaLAPACK is built on top of BLACS (Basic Linear Algebra Communication
Subroutines).  BLACS has been implemented on MPI, but it is currently being
modified to support contexts.  For more information, see:

You cannot download BLACS yet, but it should be available soon.  Once you
have BLACS, you can easily install and use ScaLAPACK.
