Quad-core enabled parallel Haskell benchmark entries, for the 64 bit quad core benchmarks game.

[edit] 1 Advice

  • Check the GC stats with +RTS -sstderr -RTS, if that number if over 5%, use -HxxxM to set a better default heap size. (Note *this is probably not permitted by the "initial allocation area rule" for the binary-trees benchmark).
  • Use N capabilities for SMP, e.g. +RTS -N4 -RTS, for the quad core.
  • Take the single threaded, fast programs and parallelise them
  • Parallel strategies are the lightest way to add SMP capabilities.
  • Contact dons or sbahra on #haskell for access to a quad or eight-way benchmark machine, before uploading.
  • See if you can use the new parallel GC to good effect: no entries currently do.
