PETSc: Portable, Extensible Toolkit for Scientific Computation

The Portable, Extensible Toolkit for Scientific Computation (PETSc), is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. It employs the Message Passing Interface (MPI) standard for all message-passing communication.

Note

To install the PETSc and petsc4py packages use:

$ python -m pip install numpy
$ python -m pip install petsc petsc4py

Tip

You can also install the in-development versions with:

$ python -m pip install cython numpy
$ python -m pip install --no-deps https://gitlab.com/petsc/petsc/-/archive/main/petsc-main.tar.gz

Provide any PETSc ./configure options using the environmental variable PETSC_CONFIGURE_OPTIONS.

Do not use the PETSc ./configure options --with-cc, --with-cxx, --with-fc, or --with-mpi-dir. Compilers are detected from (in order): 1) the environmental variables MPICC, MPICXX, MPIFORT, or 2) from running the which mpicc, which mpicxx, which mpifort commands.
