**Subject: New Version of NETLIB at ornl.gov**

We just installed a new version of netlib at ornl.gov.

This version allows a user to set the chunk size for retrieving

large files, so things don't get split up into pieces. As an example,

to receive the postscript file of the Linpack Benchmark Report

in one mail message you could send the following two lines in a mail

message to netlib@ornl.gov:

mailsize 450k

send performance from benchmark

you would then receive one file with the information.

(Unfortunately not all gateways allow large messages. If there is a

gateway between netlib@ornl.gov and your machine that doesn't allow

messages of this length, you will have to use the default mode of

message splitting. However, the recombining has been made simpler:

a user needs to strip off the mail headers and ``sh'' the resulting

shar files, in any order, to recompose the original file.)

There are a few additional new features, try: ``send index''

for all the details.

Regards,

Jack and Bill

**Subject: Information on CFD Codes Sought**

Colleagues,

I would be pleased to receive information and opinions on the currently

available public domain CFD codes. The fluid flow problem includes

the following attributes (the complete description is too long to include):

1. Flow is subsonic (slow).

2. There are regions of compressible flow caused by large

temperature gradients.

3. Soret (multi-component) diffusion should already be modeled,

or be easily added.

4. Irregular geometries are a must, but we have grid generation

routines available.

The code should be well documented and fairly robust (graphics

not necessary).

Your cooperation would be appreciated,

Jeff Scroggs

**Subject: TEX Torture Test**

Does anyone know where I can get a torture test for TEX. I know Knuth

mentions such a text for TEX 82, but I've never seen the test. Can

anyone provide the test to me, or tell me where I can get the test?

**Subject: CAC-NET (Continuous Algorithms and Complexity)**

CAC-NET AVAILABLE FOR USE

CAC-NET is an electronic conferencing system for people interested in

continuous algorithms and complexity. It is similar to the NA-NET

system that has been successfully used by the numerical analysis community.

Continuous algorithms and complexity is a rapidly growing field which

studies algorithms and computational complexity for continuous

mathematical problems which often arise in science and engineering.

By computational complexity we mean the intrinsic difficulty and

optimal algorithms for solving such problems. Examples of the

problems that are being studied include: ordinary and partial

differential equations, continuous optimization, multivariate

integration and approximation, matrix multiplication, and systems of

polynomial equations. Applications of continuous algorithms and

complexity to various disciplines are also of interest.

Material appropriate for distribution on CAC-NET include:

Announcement of research results

Discussion of research questions

Report and paper availability

Announcement of forthcoming Journal articles

Address changes

Announcement of available positions

Forthcoming meetings

Material is distributed to the CAC-NET in the form of a newsletter,

the CAC Digest. You may submit material to the CAC Digest in the form

of an electronic mail message addressed to cac.digest@cs.columbia.edu.

To receive information on CAC-NET, including information on how to join,

send mail to cac.help@cs.columbia.edu. This is an Internet address.

If you are on Bitnet, please make the appropriate adjustment. If you

have questions or comments send mail to cacnet@cs.columbia.edu.

Please note that, depending on network delays, you may not receive a

reply immediately. If you are unable to reach CAC-NET you can send

mail to

**Subject: The Responsibilities of Editors to Referees**

There is another matter with respect to refereeing that I would like to

raise. It concerns the responsibilities of editors towards their

referees. I think that if there is a disagreement between referees or

if an editor disagrees with a report, the editor should attempt to

achieve consensus by sending referees copies of other reports. Of

course referees are sometimes wrong (even me), but majority voting is

not the way to procede - one referee may have found a snag that the

others have overlooked. Of course, in the last resort the editor may

have to reach a decision between conflicting advice, but the referee

whose advice has not been taken should feel that he or she has had

every opportunity to present his or her view and should understand that

there is scope for a difference of opinion.

I have to admit that my reason for raising this is personal. An editor

recently decided to ignore my advice. It is clear from subsequent

correspondence that he did not even understand the point that I was

making. Probably I did not explain it adequately, but he did not even

try to reach consensus. I have now returned another paper that he has

sent to me. Why should I spend time writing a report that is likely to

be ignored?

I am an associate editor myself of two journals. With this hat on, I

feel that my referees need to be cosseted. Many years ago, I was sent

a copy of the other referee's report, and found this interesting. Since

then I have always copied my corresponence with the author to the

referees, including copies of other referees reports.

**Subject: Parallel Circus XI: Preliminary Announcement**

PRELIMINARY ANNOUNCEMENT

XI Parallel Circus

Location: Minneapolis, Minnesota

Dates: April 24-25

The next Parallel Circus will be held at the University of Minnesota

and will be sponsored by the Computer Science Department, Cray

Research Inc, and Minnesota Supercomputer Institute. The dates for the

meeting are Friday, Saturday April 24, 25.

What is the Parallel Circus? It is an informal meeting (the agenda is

organized at the meeting) of persons engaged in scientific computing

with emphasis on parallel and vector computing.

The circus is unique in that it is VERY informal, and thus allows us

to talk about the very latest results as well as interesting work in

progress. In our previous meetings there has been lots of informal

discussion and a very healthy mix of industrial and academic

participants. We expect a very exciting meeting since there is such an

extensive group of researchers in the Minneapolis area.

Details concerning the place of meeting and accomodations will soon be

provided.

There is modest support from the National Science Foundation for student

travel to the Parallel Circus XI. Those students requesting support should

send a one page proposal to Circus 92 (circus92@cs.umn.edu) giving the

reasons for attending the meeting, and a budget for expenses. The

student(s) should indicate their research interests and plans. A

letter verifying that the student is in good standing should be sent

independently by a faculty adviser. This letter should give the

student's GPA. We will be pleased to consider joint proposals which

would include the expenses of several students.

The deadline is 7pm (CST) on March 23 and we will try to get a

response by March 28. Correspondence by e-mail is desirable.

Organizers: Gene Golub, Bill Harrad, Ahmed Sameh, Apostolos Gerasoulis

Local Committee: Don Truhlar, Michael Olesen
