[petsc-dev] [petsc-users] release of PETSc 3.1

[Keita Teranishi]

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?

Thanks,

    PETSc users,

     We are pleased to announce the release of PETSc 3.1; we urge all  
users of PETSc 3.0 and earlier versions to upgrade in the near future.

     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
