Subject: Need Integration and Hankel Function Routines
Does anyone know/have a:
1 - Fortran subroutine to compute a double integral with UNEQUALY
spaced tabulated values.
2 - tabulated values of hankel functions(spherical bessel functions of
third kind as defined in Abromowitz 10.1.1) h2n(z) for

Subject: References on Parallel and Vector Computing
During the spring semester, I am teaching a course on numerical analysis for
vector and parallel computers. I have taught this in the past, but have not
kept up with the literature as well as I should have. I know of several books
that cover topics of interest for such a course, but would like to have the
suggestions of others to bring me up-to-date on the literature at the level
of texts (e.g. Ortega; Dongarra, et al) and survey papers (e.g. the recent
SIAM Review papers on methods for dense and sparse systems on parallel
machines). I will compile a summary of whatever suggestions I receive, to be
made available to others.

Subject: Celebration for Gene Golub
A DAY TO CELEBRATE GENE GOLUB'S BIRTHDAY
As part of the Workshop on Iterative Methods on Sparse and Structured
Problems, sponsored by the Institute of Mathematics and its Applications
(IMA) at the University of Minnesota, February 24-March 1, 1992, the last
full day of the workshop, Saturday, February 29, 1992, will be a special day
to honor a very special person, Prof. Gene Golub, on the occasion of his
sixtieth birthday. We would like to invite you to participate in this very
happy occasion.
A preliminary outline of the schedule for that day, Saturday, February 29,
1992, is as follows:
On Friday evening, Feb. 28 the IMA will sponsor a buffet reception/dinner
at the Campus Club, on the University of Minnesota Campus.
On Saturday, Feb. 29, during the day, a workshop of a more historical or
anecdotal nature will take place on the University Campus. Jack Dongarra
and Paul Van Dooren are handling the details of the program. If you would
like to contribute to the informal talks addressing Gene's impact on
various areas of research, his unique style of interacting with people,
his travel habits, anecdotes, a survey of areas where he has had an impact,
etc, please contact either Jack (dongarra@cs.utk.edu) or Paul
(vdooren@uicsl.csl.uiuc.edu) as soon as possible, but in any case before
November 30th.
On Saturday Evening, we will hold a Banquet in the tradition of Gene (that's
right - at a Chinese restaurant!). Bill Gear will the after dinner speaker.
We plan to provide bus transportation to the Restaurant. To help defray
part of the expenses for Friday and Saturday, we will have to charge individual
participants $15 per person (this includes the transportation and banquet).
Hotel rooms are available at the Day's Inn, about 4 blocks from Campus, at
the special rate of $34/night (plus tax). Please call them directly to
reserve your room. The special rate is being held only until Feb. 9, 1992.
You should be able to guarantee your reservation with a credit card. The
address/phone number is
Day's Inn University
2407 University Ave. S.E.
Minneapolis, MN 55414, USA
phone (612)-623-3999
or (612)-623-4262
(when making reservations, ask for Joyce Turner, or state that
you are visiting the Institute of Mathematics and its Applications)
If you would like to attend the celebration and banquet, we would like to
hear from you by January 15th, 1992. Please send e-mail to
boley@cs.umn.edu
to receive a copy of an registration form.
I apologize for the lack of a personal reply to all you folks who sent me a
message expressing interest in this workshop.
We look forward to hearing from you.

Subject: Bulgarian Mathemtician Looks for a Position
I know a Bulgarian numerical analist who is interested in getting
a temporary position in a university or a research institute for one or
two years.
He is working at the Center for Informatics and Computer Technology
at the Bulgarian Academy of Sciences. He is interested in (i) finite
elements with emphasis on local refinement, (ii) domain decomposition,
and (iii) linear algebra. He has done also some research on parallel
algorithms for computers with shared memory (they have transputers
at the Center for Informatics and Computer Technology). He is interested
in research connected with parallel computers (not only computers
with shared memory).
The Bulgarian Academy of Sciences is the highest research institute
in Bulgaria. The best students from the universities are selected for
the Bulgarian Academy of Sciences. In the Center for Informatics
and Computer Technology they are now very interested in
establishing contacts with universities and research institutes in
the Western countries.
If anybody knows about a suitable position, contact me, please
and I shall pass some more information. Thank you very much in
advance.

Subject: Utah Workshop in Distributed Computing
UTAH SUPERCOMPUTING INSTITUTE
FALL WORKSHOP ON DISTRIBUTED COMPUTING
The Utah Supercomputing Institute(USI), the IBM Corporation and Batelle
Pacific Northwest Laboratory are sponsoring a Workshop on Distributed
Computing to be held November 13 and 14 at the University of Utah in
Salt Lake City. Leading software developers from government, industry
and academia will make presentations at the workshop. The first
sessions will be held in the Mariott Library Auditorium on
on campus. The second day of the conference will be
held at the University Park Hotel, which is adjacent to the campus.
The second day will be a joint meeting with the Future Technologies
Cluster Users Group (CUG) sponsored by IBM's Advanced Workstation
Division in Austin, Texas (the designers and manufacturers of the
RS/6000 line of scientific workstations).
The field of distributed computing encompasses topics that range from
distributed database systems and remote graphical display to clustered
computing. The scope of the workshop is limited to the latter area,
which is concerned with the use of scientific workstations connected
by local area networks for parallel and batch processsing.
The primary objectives of the workshop are to educate the user
community on current activity in clustered computing and to help
researchers and programmers evaluate the potential impact of clustered
computing on their work. To achieve these objectives,
speakers at the workshop will focus on issues such as the usefulness,
cost and availability of tools for accomplishing clustered computing.
Among the topics that will be addressed are message-passing libraries,
parallel compilers, network debuggers, graphical user interfaces and
performance analysis tools. Case studies drawn from the experiences
of researchers will also be included.
