Subject: Applied Linear Algebra Year

As many of you know, there will be an APPLIED LINEAR ALGEBRA YEAR at
the IMA of the UNIVERSITY of MINNESOTA, beginning in September, 1991.
The program and list of confirmed attendees is available through
netlib. Here's how to get some information as TeX files. Send the
following msgs to netlib:

 send index from meetings 
 send la-ima from meetings.

I think this is going to be a very exciting year. We owe much thanks
to Dick Brualdi for his great efforts in putting this program
together.

Subject: Methods for Parabolic Equations on (0,inf).

I have developed an algorithm for efficiently solving parabolic equations on
the positive axis.  However, since this isn't my usual area of research I am
not familiar with the literature and am a little concerned that I have 
discovered something already known.  Accordingly, I would appreciate any
references to papers in this area which the na-digest community might be
able to provide.  I haven't been able to find much, frankly.

Thanks much  --  Jim Epperson

Subject: Timing Routine for the RS6000

Hi,

I want to run some benchmark programs (LINPACK, etc.) on
an IBM RS6000 system. However this requires a function SECOND
to return the cpu time. Usually, SECOND just calls ETIME, but
ETIME is not available on this system. If anyone has a version
for the RS6000, please email me a copy.
Thank you.
