Engineering and Scientific Subroutine Library for the Risc System/6000.
This is a set of high performance mathematical subroutines for matrix
operations, dense and spare linear algebraic equations, Eigensytem analysis,
Fourier transforms, convolutions and a few other things.

The routines are designed to be called from Fortran programs.  They
can be called from C programs, but they use the Fortran convention
for storing matricies.

All of the routines are tuned for performance on the Risc
System/6000, and the performance is quite impressive.  

There is an ESSL product for the 370 architecture machines as well,
and the calling sequences between the the Risc System/6000 version
and 370 version of the product are almost all identical.  The
370 version makes use of the vector facility on 3090 machines which
have it.
