PETSc contains modifications of routines from
- LINPACK (matrix factorization and solve; converted to C using f2c and then hand-optimized for small matrix sizes)
- MINPACK (sequential matrix coloring routines for finite difference Jacobian evaluations; converted to C using f2c)
- SPARSPAK (matrix reordering routines, converted to C using f2c, this is the PUBLIC DOMAIN version of SPARSPAK)
- libtfs (the scalable parallel direct solver created and written by Henry Tufo and Paul Fischer).
Instrumentation of PETSc
- PETSc can be instrumented using the TAU package [check installation instructions].
