Quad-core enabled parallel Haskell benchmark entries, for the 64 bit quad core shootout.
Advice
- Check the GC stats with +RTS -sstderr -RTS, if that number if over 5%, use -AxxxM to set a better default heap size.
- Use N+1 capabilities for SMP, e.g. +RTS -N5 -RTS, for the quad core.
- Take the single threaded, fast programs and parallise them
- Parallel strategies are the lightest way to add SMP capabilities.
