Subject: New Version of NetSolve

New Release of NetSolve/GridSolve Version 2.0

A new and more powerful version of the well-known grid middleware
NetSolve/GridSolve has just been released. NetSolve 2.0, like its
predecessors, is a client-server-agent system that enables users to solve
complex scientific problems remotely using distributed resources on a
computational grid. The system provides users access to both hardware and
software computational resources distributed across a network. When a user
submits a problem to the NetSolve agent, the agent searches the network of
computational resources that has registered with it, chooses the best one
(or set) available, solves the problem, and then returns the solution to the
user. Load balancing for good performance and retry for fault-tolerance are
handled automatically by the system. Version 2.0, which builds on NetSolve's
traditional strengths, adds capabilities and robustness both to NetSolve's
native environment and to its integration with other grid middleware, such
as Condor-G.
NetSolve's traditional strengths are its ease-of-use and its broad support
for critical numerical software packages. For ease-of-use, NetSolve bindings
exist for the most common scientific programming environments; Fortran, C,
Matlab, Mathematica. Moreover, many of the most important numerical and
scientific libraries (e.g. Linear Algebra, Optimization, Fast Fourier
Transforms) are easily integrated into the NetSolve server software, and
users can also add their own special libraries. Finally, NetSolve has been
designed to avoid restrictions on the type of software components that can
be integrated into the system, and users with various types of applications
have been able to incorporate their own packages into NetSolve with relative
Version 2.0 enhances these basic capabilities in two directions. There are
enhancements to NetSolve's native environment to make it even easier to use,
more capable, and more secure. And there are additions to NetSolve that
enable it to more easily interoperate with, and leverage the power of, other
leading grid environments. The most notable feature of the latter is the
incorporation of GridRPC into NetSolve; this expanded version of the
NetSolve environment is called GridSolve. Grid RPC is an evolving standard
from the Global Grid Forum (GGF).
NetSolve 2.0 is an open source package and can be freely downloaded from the
ICL Web site
Funding for the NetSolve effort is provided by grants from the National
Science Foundation (NSF) through the NPACI and the NMI programs and the
Department of Energy (DOE) through the MICS effort.

Subject: Article in American Scientist About Interval Computations

Dear Friends,

A popular article about interval computations has appeared in this
month's Computing Science column of "American Scientist".

American Scientist is a journal published by Sigma Xi, an international
Scientific Research Society, that combines thosuands of researchers of
differemty disciplines from all over the world, including numerous Nobel prize

This column, written, as usual, by Brian Hayes, is currently available
for free from the journal's website
