Software for Compiling/Running Cactus

Essential: C/C++, CVS, Perl 5, gmake, MPI
  • CVS is just used for checking out the code and is essential only because of its convenience.
  • Just about any implementation of MPI is OK (Native, LAM, MPICH, ...)
  • The flesh does not require C++, but a couple of the computational toolkit thorns require it.
Needed for Real Applications: Fortran 90, HDF5 (with virtual file driver configured).
  • Many of the Numerical Relativity thorns are written with Fortran 90
  • HDF5 is used for some output, in particular for several of the output methods which we use for standard demonstrations.
Useful: PETSc, PAPI, MPICH-G2, LAPACK/BLAS

PAPI

PAPI aims to provide the tool designer and application engineer with a consistent interface and methodology for use of the performance counter hardware found in most major microprocessors. We don't use in much in Cactus at the moment, but we really want to. One problem is that it requires a patched kernel for Linux still. PAPI can be freely downloaded from the University of Tennessee.

HDF5

Our favorite file format for binary output data from large simulations, HDF5 is a general purpose library and file format for storing scientific data. HDF5 can be freely downloaded from the NCSA. We make a lot of use of streaming data with HDF5, this means that when it is installed the virtual file driver needs to be configured. See the Cactus HDF5 HOWTO for more details.

MPICH-G2

Used for coupling multiple machines for MPI runs. MPICH-G2 can be freely downloaded from North Illinois University.

PETSc

A suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. Cactus uses it at the moment for solving elliptic equations with some applications. It employs the MPI standard for all message-passing communication. (And applications must be compiled with the same MPI which was used for compiling PETSc). Freely downloadable from Argonne National Laboratory.
