Usage Information:

PETSc is installed in /usr/apps/math/petsc on Abe. Current version being configured is 2.3.3-p7. For documentation on using PETSc please start at the PETSc-2 documentation page.

Builds (PETSC_ARCH) of devel/debug and optimized versions of:
devel/debug: abe-intel10, abe-intel10-c++ abe-intel10-complex, abe-gnu3-c++
and
optimized: abe-intel10-opt, abe-intel10-opt-c++ abe-intel10-opt-complex abe-gnu3-opt-c++ abe-gnu3-opt-c++
are available.

All builds use MVAPICH2 as the MPI implementation, which is the default MPI on Abe.
For the intel10 builds, add @mvapich2-1.0-intel to your ~/.soft file. For the gnu builds, add @mvapich2-1.0-gnu to your ~/.soft file.

If you have an existing PETSc application with a Makefile or script with uses the PETSC_DIR and PETSC_ARCH environment variables, set PETSC_DIR to /usr/apps/math/petsc/petsc-2.3.3-p7 and PETSC_ARCH to one of the builds above and make your application.

External Package builds:
HYPRE: abe-intel10-hypre abe-intel10-opt-hypre abe-intel10-c++-hypre-superludist abe-intel10-opt-c++-hypre-superludist abe-intel10-opt-hypre-superludist

Example usage of PETSc
Have the following in your ${HOME}/.soft file before the @default or the @teragrid lines
+intel-mkl-9.1.023
@remove +mvapich2-intel
@mvapich2-1.0-intel
