When I completed the top patches so that 2.5 worked on the Balance, I took
it over to the Symmetry and found that it had a couple of incompatibilities
with the Balance.  Fortunately, there were system macros that produced
the correct fields on each machine, so I just substituted those for
direct field references and checked that the macros existed and did the
same thing on the Balance.  It compiled and worked on the Symmetry, so
off went the patches.  Now I find out I should have recompiled with the
new macros on the Balance.  Turns out that Sequent uses a function (macro?)
named imin in several of the system macros.  Only problem is, it isn't
defined *anywhere* in the /usr/include directory and obviously doesn't
exist in the libraries, since ld can't find it.  So, to make a long
story short, you should add the following three lines to the end of
the #ifdef sequent section at the end of the #include sections of
display.c and top.c:

#ifndef imin
#define imin(i,j)	((i) < (j) ? (i) : (j))
#endif

This has been compiled and works in both the Balance and the Symmetry.
Sorry about the mixup -- I should have recompiled it.  One never knows
what important system macros are unusable.

Got Top V2.5 compiled and running on both our Balance and Symmetry.  It's very
useful.  I can finally indentify what and who is using (and/or abusing) the
systems.

Thanks Mark!

Subroutine to solve linear system of equations

Hello,
I am looking for a fast fortran subroutine to solve (in parallel)
dense system of  linear equations ( with at most 1,000 variables).
I really appreciate if someone can mail me such a subroutine. Thanks

I have two parallel programs that will do your job. The first,
is a parallel version of the DGEFA (SGEFA) linpack subroutine.
The second is a sophisticated cholesky solver written by somebody
at ODU. It is  a very fast solver specially for banded matrices.
Both programs are written using the Force which is a parallel
programming language that extends fortran and runs on The Sequent,
Encore, Alliant, Flex and Cray computers. Let me know if you
are interested.
