PeIGS Available

We are pleased to make PNL's parallel eigensolver PeIGS available to
the public.  It can be obtained via anonymous ftp from ftp.pnl.gov
(192.35.193.200) in the directory pub/peigs or via World Wide Web at

http://www.emsl.pnl.gov/docs/peigs/peigs.html

An example of the ftp session is listed at the bottom of this note.

PeIGS is a collection of parallel routines for solvin g the general
and standard symmetric eigenproblem.  It is being developed at the
Department of Energy's Pacific Northwest Laboratory operated by
Battelle Memorial Institute.  The authors are David Elwood, George
Fann, and Richard Littlefield.

PeIGS runs on Intel Paragon, Intel DELTA, Intel IPSC/860 using native
NX calls.  PeIGS also runs on IBM SP-1. IBM SP-2, Cray T3D,
SGI-PowerChallenge, and clusters of workstations using TCGMSG.  TCGMSG
is available as part of the Global Array distribution available
at ftp.pnl.gov in the directory pub/global.  A Global Array-PeIGS interface
is available in the Global Array distribution.

Additional Interfaces to MPI and ... should be easily integrated since
PeIGS uses only blocking send and blocking receive.  All other
communication functionalities are self contained.  If people are
interested in other message passing or shared memory interfaces we may
be able to work with you to set this up.

*****

peigs20.tar.Z is a unix compressed tar file which can be extracted
(on a unix system) using the commands:

uncompress peigs.tar.Z
tar -xvf peigs.tar

or

zcat peigs.tar.Z | tar -xvf -

The preceding commands will create a subdirectory ./peigs2.0 in the
directory where the command was executed.  In ./peigs2.0 there
will be README and INSTALL files which give more details on peigs.

Documentation on line using texi format or in postscript
format in the directory ./peigs2.0/doc

****

peigs20.uu is an ASCII file created from peigs20.tar.Z by uuencode.
To decode peigs.uu use the command:

uudecode peigs20.uu

This will create the file peigs20.tar.Z in the current directory, which
can then be extracted as noted above.
