[comp.sys.sequent] Subroutine to solve linear system of equations

deleone@monterey3.cs.wisc.edu (Renato De Leone) (09/09/88)

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.
