<DIV><SPAN class=890273613-13052008><FONT face=Arial size=2>I'm thinking about
using petsc to solve a linear system (Ax=b) using parallelization on a couple of
linux computers. It is very important for my system (electromagnetics) to use a
direct solver, such as UMFPACK. Iterative solvers perform very poorly.

<DIV><SPAN class=890273613-13052008><FONT face=Arial size=2>My question
is: I can see that UMFPACK is not listed (<A
href="http://www-unix.mcs.anl.gov/petsc/petsc-2/documentation/linearsolvertable.html">http://www-unix.mcs.anl.gov/petsc/petsc-2/documentation/linearsolvertable.html</A>)
on the petsc page. Are there any plans to expand petsc to also include
petsc?</FONT></SPAN></DIV>

<DIV><SPAN class=890273613-13052008><FONT face=Arial size=2>The UMFPACK homepage
says that there exist a parallization for UMFPACK by Steve Hadfield. Can his
parallelization be used with petsc?</FONT></SPAN></DIV>

<DIV><SPAN class=890273613-13052008><FONT face=Arial size=2>I must add, that
although I like numerics and maths I do not intend to program 'from
scratch'. </FONT></SPAN></DIV>
