Subject: LAPACK-to-Java

The first public release of the Java LAPACK (version 0.3 beta) is available
for download at the following URL:

The JLAPACK project provides the LAPACK and BLAS numerical subroutines
translated from their Fortran 77 source into class files, executable by
the Java Virtual Machine (JVM) and suitable for use by Java programmers.
This makes it possible for a Java application or applet distributed on
the web to use established legacy numerical code that was originally written
in Fortran. The translation was accomplished using a special purpose
Fortran-to-Java (source-to-source) compiler.

The Java LAPACK is distributed as several packages of class files
which the Java programmer may import similarly to the java.lang.Math
package. Source code is also included for reference, although for
technical reasons, it may not be possible for users to recompile code
containing GOTOs.

These class files are provided to enable LAPACK capabilities, not to
provide a highly efficient version of the library.
Although over time we expect an efficient Java version of the BLAS to
be available.

There is some javadoc-generated documentation for BLAS and LAPACK at:

Subject: Announcing PSPASES 1.0 and WSSMP 3.7

"PSPASES : A Scalable Parallel Direct Solver Library for Sparse Symmetric
Positive Definite Systems"

by Mahesh Joshi, George Karypis, Vipin Kumar
Department of Computer Science, University of Minnesota, Mineapolis.
Anshul Gupta
IBM Thomas J. Watson Research Center, Yorktown Heights, New York.

We are glad to announce a new version (1.0) of PSPASES.

PSPASES is a stand-alone MPI-based parallel library for solving linear
systems of equations involving sparse symmetric positive definite matrices.
The library efficiently implements the scalable parallel algorithms
developed by authors, for each of the four phases of direct solution
method; viz. ordering, symbolic factorization, numerical Cholesky
factorization, and solution of triangular systems.

PSPASES is implemented using standard MPI and BLAS calls, which makes it
portable to most of today's parallel computers and networks of
workstations. We have tested PSPASES extensively on IBM SP, network of
IBM RS6000 workstations, Cray T3E, SGI Origin 2000 and PowerChallenge

PSPASES uses ParMETIS and METIS as default libraries for computing fill-
reducing ordering, but it also accepts user supplied ordering. Different
functional interfaces are provided for each of the phases of the solver
and a simple interface is also provided for easy use. The user can use
these interfaces to solve multiple systems with same nonzero structures;
to solve same system for multiple right hand sides; and to get different
statistical information such as the memory requirements of the solver
and the quality of the ordering.

Visit the PSPASES web site at

to obtain the software, the manual, related technical papers, usage notes,
and to see some performance benchmarking results. Please read the terms
and conditions for use, given at the website, before downloading and
using the PSPASES software.

If your machine does not have access to the web, then you may obtain the
software via an anonymous ftp to "". Change the directory to
users/kumar/mahesh and get the files pspases-1.0.tar.gz, README.INSTALL,
and README.USAGE (remember to use binary transfer mode).

Any comments, questions or bugs regarding PSPASES can be directed to
Mahesh Joshi (

"WSSMP: Watson Symmetric Sparse Matrix Package"

We are pleased to announce a new version (3.7) of WSSMP.

for IBM SP and RS6000 systems, as WSSMP. The WSSMP package contains
robust industrial strength code for serial and parallel solution of
sparse symmetric positive definite and indefinite systems. WSSMP has
been clocked at up to 450 MFLOPS on an RS6000/397 workstation and up to
24 GFLOPS on a 64-processor SP with model-397 nodes. Documentation for
WSSMP is available at

Please read the terms and conditions of use, given in the manual, before
using the WSSMP software.

Any questions pertaining to WSSMP may be directed to Anshul Gupta
A faster version of the solver with enhanced functionality is available.

Subject: Workshop on Applied Parallel Computing


Umea University
June 14-17, 1998


High Performance Computing Center North (HPC2N) is hosting the
fourth International Workshop on Applied Parallel Computing
(PARA98) in June 14-17, 1998 at Umea University, Umea, Sweden.
The general theme for PARA98 is Large Scale Scientific and
Industrial Problems focusing on:

* High-performance computing applications in academia and industry,
* Tools, languages and environments for high-performance computing,
* Scientific visualization and virtual reality applications in
academia and industry,
* Future directions in high-performance computing and networking.

The PARA98 meeting is aimed to be an international forum for idea and
competence exchange for specialists in parallel computing,
visualization, etc and scientists from industry and academia solving
large scale computational problems. Another important aim of the
PARA meetings is to strengthen the ties between HPC centers,
academia, and industry in the Nordic countries as well as worldwide.

The meeting starts with a one day tutorial followed by a three day
workshop. There will be 20 invited 45 minutes lectures and around
70 contributed 20-25 minutes presentations. The PARA98 Proceedings
will be published by Springer-Verlag in their Lecture Notes in
Computer Science series.
