New release of Cactus problem solving environment

 Potsdam 20 Apr 00 The Cactus consortium has released a new version (beta 7) of its problem solving environment Cactus. Cactus is an open source problem solving environment designed for scientists and engineers. Its modular structure easily enables parallel computation across different architectures and collaborative code development between different groups. Cactus has been tested on Linux, Cray T3E, Dec Alpha, HP Exemplar, IBM SP2 and SGI Irix.

Cactus is an open source problem solving environment designed for scientists and engineers. Its modular structure easily enables parallel computation across different architectures and collaborative code development between different groups. Cactus originated in the academic research community, where it was developed and used over many years by a large international collaboration of physicists and computational scientists.

Cactus works with plug-ins, wich are called "Util Thorns". New and changed thorns in this release are:

  • CactusPUGH/PUGH - Added manual decomposition (donated by Matei Ripeneau), and changed parameter names for manual processor topology. See the README in PUGH/doc for more information.
  • CactusPUGH/PUGH - Major changes to remove the old pGF and implement grid functions as a special case of a grid array.
  • CactusPUGH/PUGH - Implemented support for constant sized arrays on each processor
  • Added CactusBench arrangement to contain benchmarking thorns. Currently there is just BenchADM which contains the staggered leapfrog evolution method for CactusEinstein/ADM with the macros expanded, and some optimisations.
  • New thorn: IDScalarWaveC, initial data for the scalar wave equation all in C
