The directory contains a small number of examples.  The files are
separated according to the machine type where tests have been
performed.   There are three examples in most of the directories.

simple  -- a Fortran 90 example
simplec -- a C example
simple77-- a Fortran 77 example

The sequential version of the programs are located directory SUN.  The
makefiles in C90 and RS60 and SGI will make softlinks to the files in
SUN when needed.

Two sets of parallel examples exist in directory T3E and psp.  The
examples in T3E are MPI counterparts of those in directory SUN.  The
example shbpsp in psp directory use PSPARSLIB
<http://www-users.cs.umn.edu/~saad/software.html> to perform the
distributed sparse matrix-vector multiplications.  It reads a sparse
matrix in Harwell-Boeing format and computes some of its eigenvalues as
specified on the command line.  The matrix must be symmetric and it must
be stored in RUA format.  A utility program rsarua is provided with the
example to convert RSA files into RUA.
