6) Message boards : Project Staging Area : Detailed stats for PRPNet (Message 126929)
Posted 1 day ago by Profile Michael GoetzProject donor
That's partly true.

It's true for the current PRPNet projects, but some older PRPNet projects were 10:1.

Also, your BOINC PSA credit also includes manual sieving credit, and sometimes credit from other sources such as manual testing. For many people it's likely that their BOINC PSA credit will not be exactly 20% of their PRPNet points.

5%?

8) Message boards : Problems and Help : GPU computation error for geforce 1080 ti on genefer projects (Message 126924)
Posted 1 day ago by Profile Michael GoetzProject donor
PPS Sieve (cuda version on GPU) is a yes, AP27 is a nope sadly. AP27 and the "Do You Feel Lucky" tasks both return "Computation Error" immediately like the GFN tasks. Thanks again so much for helping!!!


That means its a video driver problem. The driver you have installed doesn't support OCL. At a minimum, you'll need to install the full Nvidia drivers, which you can download from their website.

During TDP does the advancement on projects increase in similar fashion to or as much as the Challenge series? Or do they advance like any "normal" non challenge day? Understandably GFN16 and PPSE (to me) would advance quicker due to them getting hit harder due to the completion times. Just curious if there is a "spike" across the board.


It's what you would expect. Large increases in GFN16 and 17MEGA, and PPSE and PPS-MEGA.
