For those of you who are running PRPNet ports that make use of PFGW, and especially if you have a recent Intel CPU (Sandy Bridge, Ivy Bridge or Haswell), you will want to check out the new release of PFGW. The main change is that it now uses the same version of gwnum that LLR does i.e. supports FMA3 for improved performance on Haswell, and also improved performance on AVX-capable chips.
The binaries are here: http://sourceforge.net/projects/openpfgw/files
No Linux build yet, but hopefully soon.
You can just drop the new version in place of the older one in your prpnet programs directory, and should see a significant speedup.
