Greetings, I just attempted my first package, of PETSc, the Portable Extensible Toolkit for Scientific Computing, project homepage at http://www-fp.mcs.anl.gov/petsc/ . It depends on MPI, BLAS/LAPACK, and xlib. It's largely a beowulf thing. Would someone be interested in sponsoring me? First cut is in http://lyre.mit.edu/~powell/debs/ (or follow the links buried in http://lyre.mit.edu/~powell/debian.html). Thanks, -Adam P.
