Barry, It is great to hear the new release of PETSc. I am wondering if you have any performance numbers of the new triangular solution. Is there any document/publication?

We (Hong Zhang and Shrirang Shri) have provided new triangular solve routines for all the sparse matrix data structures which should result in a good performance improvement with many of the solvers. As always the changes/additions to the PETSc API can be found at http://www.mcs.anl.gov/petsc/petsc-as/documentation/changes/31.html please report all installation and usage problems to petsc-maint at mcs.anl.gov Thanks for your support, Barry
