%description
The BLACS (Basic Linear Algebra Communication Subprograms) project is 
an ongoing investigation whose purpose is to create a linear algebra 
oriented message passing interface that may be implemented efficiently 
and uniformly across a large range of distributed memory platforms.

The length of time required to implement efficient distributed memory 
algorithms makes it impractical to rewrite programs for every new 
parallel machine. The BLACS exist in order to make linear algebra 
applications both easier to program and more portable.
