gentryx's Journal: LibGeoDecomp: an Auto-parallelizing Stencil Code Library

LibGeoDecomp is a C++ class template based library which provides a smooth transition for researchers to port their existing stencil based simulation codes to parallel computers -- from multi-cores to MPI clusters and GPGPUs. In a nutshell, one only has to replace the accesses to neighboring elements by the library functions and let LibGeoDecomp handle the main time and space loops. Essentially the library takes over the parallel programming part, which can be of great help for scientists who'd rather focus on the physics (or chemistry or what ever) part of their research and less on the computer science required to carry it out.
  It's currently in alpha state, but is already being used for medium sized simulations requiring 200 GB of RAM and prodicind 2 TB of output data.

DISCLAIMER: yes, this this my PhD project, so I'm biased.
