1) Message boards : Generalized Fermat Prime Search : Genefer 3.3.5 is live! (Message 146127)

Thank you for the new software, and thanks to all the testers. I appreciated your work.
2) Message boards : Number crunching : Multi-threaded LLR on a Threadripper 1950X (Message 122410)
Posted 843 days ago by Profile Adam J BavierProject donor
Do we have any Threadripper (or Ryzen in general) crunchers here willing to do some testing of their own and post their results here?


I have a 1950X, with good fast RAM at 3200MHZ and CAS 14.

I'm willing to run a few tests. What few tests are you interested in? Give me specifics please.

I sent a request through the spreadsheet to get edit access. I have a Genefer 21 running with 14 threads. And it is using the correct app and currently 42% of my CPU as reported by Windows 10 math. Estimated completion time is in 16 hours. Link to WU (I currently can't view it) it, but the number matches: http://www.primegrid.com/workunit.php?wuid=580282641

Below is my app_info.xml and app_config.xml. Always interested in constructive feedback.

From that newest linked exe from Iain these are the estimate times I got with 250000^2097152+1 that people were using earlier in this thread.


1950X threadripper with 3200mhz Cas 14 ram. Default CPU clocks.
-nt 1 143 hours
-nt 2 78:10
-nt 3 54:08

-nt 16 17:00 dropped to 15:41 after running a few seconds.


I ran -q "2041898^65536+1" -nt 1 through the 64 bit app in Windows and it said it was probable prime. I wasn't sure if I should put my name in green in that cell or not.
5) Message boards : General discussion : BOINC Pentathlon and Manual Credit (Message 117433)

If we do not like what we are giving them with our free PCs, it is unfortunate their sayings!


I'm sure PrimeGrid and the math community really like that you are giving freely of your PCs time and computing power. You can continue to do so, and will keep getting points and recognition for you work. If you participate in the PSA manual sieving, or PRPNet work your points you turn in during May 5th to May 19th have the chance of being delayed if PrimeGrid gets chosen as a project for the BOINC Pentathlon. You will still get all points.

Thanks for the heads up.

I just enabled the project again, so that I can get up to the gold badge before GCW-Sieve gets shutdown.

I found out about the PSA manual sieving badge, so stated crunching there and I'm up to a

My newest two are and

Main goal is to get all silvers on the CPU tasks, and keep pushing hard on the GPU tasks, but I only have one computer so it will take a long while to fill out the CPU badges. Should see a Double Bronze in PPS Sieve within the next two weeks.
10) Message boards : Number crunching : Which PrimeGrid CPU Projects Support Threading or have optimized app_config settings? (Message 109756)
Posted 1280 days ago by Profile Adam J BavierProject donor
Thank you for the information. I didn't know the "llr" meant it supported threading. I'll get my config all setup now.
