Subject: Electronic References on Parallel Methods for Optimization

Dear coleagues,

I'm working in parallel methods of minimization convex smooth function
f : R^n --> R
at the set
U = {x in R^n : g1(x)<=0, g2(x)<=0, ... gm(x)<=0 }
where functions g1, g2, ... gm are convex.

I haven't appropriate literature in my country. Would you, please, give me
some names and emails of people that are in the same area of research, and
places where I can find papers in electronic form.

Subject: LP Short Course OnLine

I have added an LP short course (some lessons are under construction) at

(You could also visit my general courseware page.)

It uses my glossary and other web sites extensively, and it links to my
"Lab Manual", which I have put on the web too. The manual, itself, is as
complete as the printed version from which it was taken. But, I have not
yet completed the solutions, which are links from each exercise.

I am anxious for your comments, and candor will be appreciated. You can
e-mail me directly at, or you can use the
Comments I have put there.

Subject: Intel Supercomputer Users Group

Annual Meeting of the Intel Supercomputer Users Group

The thirteenth annual meeting of the Intel Supercomputer Users Group
will be held in Albuquerque on June 11-13. The theme of the meeting
is "Spanning the Spectrum", reflecting the broad range of Intel's
involvement in high performance computing from the world's fastest
computer to the humblest pile-of-PCs. Reflecting these different scales,
the three days of the meeting will focus on different points on this spectrum.
The first day will be devoted to the Intel/Sandia Tflop computer, the
fastest in existence. The second day will principally focus on Paragons
and related issues. The emphasis of the last day of the meeting will on
the exciting emergence of commodity cluster computing.

Social events will include a welcoming reception, a tour of the Tflop machine
at Sandia and a dinner at the top of the mountains overlooking Albuquerque.
More complete and up to date information can be found at the ISUG'97 web site The deadline for guaranteed hotel reservations
and early conference registration is May 20th.

Subject: Parallel Solution of PDE Workshop

IMA Workshop: Parallel Solution of PDE
June 9--13, 1997. Organizers: Mitchell Luskin (Univ. of Minnesota)
and Petter Bjorstad (Univ. of Bergen)

The numerical solution of the partial differential equations of continuum
mechanics is of major importance to the development of many technologies
and has been the target of much of the development of parallel computer
hardware and software. Parallel computers offers the promise of greatly
increased performance and the routine calculation of previously
intractable problems. This period of concentration and workshop will
promote the development and assessment of new approximation and solution
techniques which can take advantage of parallel computers. Topics to be
the focus of research include sparse matrix techniques, domain
decomposition methods, parallel multi-grid methods, and novel time and
space discretizations.

Registration is free. Please contact for arrangements.

The now bi-annual Gordon conference series in HPC and NII commenced in 1992
and has had its second meeting in 1995. The Gordon conferences are an
elite series of conferences designed to advance the state-of-the-art in
covered disciplines. Speakers are assured of anonymity and
referencing presentations done at Gordon conferences is prohibited by
conference rules in order to promote science, rather than publication
lists. Previous meetings have had good international participation,
and this is always encouraged. Experts, novices, and technically
interested parties from other fields interested in HPC and NII are
encouraged to apply to attend.

All attendees, including speakers, poster presenters, and session chairs
must apply to attend. We *strongly* encourage all poster presenters to have
their poster proposals in by May 13, 1997, though we will consider poster
presentations up to six weeks prior to the conference. Application to
attend the conference is also six weeks in advance.

Subject: ACM TOMS: Online Access and Reduced Backlog

ONLINE ACCESS. Full-text of articles published in the ACM Transactions on
Mathematical Software (TOMS) from 1991 to present can now be downloaded from
the ACM Digital Library at Access to complete
articles is currently restricted to print subscribers, although
tables-of-contents and search facilities are available to all. ACM will begin
offering online-only subscriptions at a reduced rate this summer.

REDUCED BACKLOG. TOMS has reduced its publications backlog to about 6 months.
(Articles to be published in June 97 were accepted during the period Nov 96 to
Feb 97.) ACM encourages authors to consider TOMS as an outlet for their work.

TOMS publishes research papers on practical aspects of mathematical algorithms
and their implementation in well-designed computer software. Topics of
interest include the methodology of math software design, testing and
evaluation; the effect of machine architecture, languages and tools on
mathematical computations; as well as concrete mathematical algorithms for
linear algebra, function evaulation, nonlinear systems, optimization,
differential equations, statistics, etc. Software in Fortran, C, C++, MATLAB,
and other languages may be included in TOMS submissions; if accepted, such
software is distinguished by inclusion in the Collected Algorithms of the ACM.
