Try this input file with gale_svn. I have done a number of runs on
the cluster here, so it should work in parallel. You may have to use
a direct solver. If you did not build petsc with mumps, you can do it
by adding
--download-mumps=yes --download-blacs=yes --download-scalapack=yes --with-blacs=yes --with-scalapack=yes
when configuring petsc. Note that Gale is only tested with Petsc
2.3.2. When running Gale, add
-mat_type aijmumps -ksp_type preonly -pc_type lu
to the command line. For example, something like
./gale_svn extension.xml -mat_type aijmumps -ksp_type preonly -pc_type lu
Cheers,
