I recommend doing out-of-source builds. For example libmesh/build-arch1$ ../configure PETSC_ARCH=arch1 libmesh/build-arch2$ ../configure PETSC_ARCH=arch2 Then you can easily switch without needing to reconfigure and recompile all of libmesh. ------------------------------------------------------------------------------ Everyone hates slow websites.
