I would appreciate if people could test the next release (3.2.4) of PFGW for Windows. I think that it will be faster than genefer for GFN testing. 3.2.4 has a change that is specific for GFN testing. You can get 3.2.4 from here: http://openpfgw.svn.sourceforge.net/viewvc/openpfgw/
If it is faster, than I will modify PRPNet to use PFGW instead of genefer. I need people who run Windows and Win64 to post the times for these tests:
for genefx64, genefer, genefer80, and PFGW 3.2.4. If you also post the hardware that you have used for the test. Do not worry that PFGW and genefer have different residues. If PRPNet is to make the switch it will be all or nothing, i.e. all PFGW or remain all genefer.
Note that these tests are important for the long term viability of the GFN project on PrimeGrid. It appears that the GFN project is running into many roundoff errors with genefer. I can modify PRPNet to use PFGW when that occurs, but I suspect that PFGW is always faster than genefer. If so, then genefer support will be removed from the next release of PRPNet.
