Posted 1 day ago by ReggieProject donor
WCG = WorldCommunityGrid. It has everything but that. Would be nice if you guys added it, thanks.

Are you referring to this page? If so, it works for mine. Does WCG show up on your homepage (https://www.primegrid.com/home.php)?

Thank you to everyone who participated in testing! PSA credit has just been awarded, and the new versions will be live on PrimeGrid very soon.
4) Message boards : Problems and Help : Only getting PPS Sieve work, though I have removed that subproject (Message 142094)
Posted 6 days ago by ReggieProject donor
You have two venues: "default" and "home". "Default" is currently set to allow many types of work, but not PPS-Sieve. "Home" is set to only allow PPS-Sieve work. Your computer is on the "home" venue. To solve this, you need to either change your venue to "default" or change your preferences for "home" instead of "default".
5) Message boards : Problems and Help : Boinc tasks available (Message 141814)
Posted 15 days ago by ReggieProject donor
The front page shows work available for each subproject, and if they run out of work, something went badly wrong on our side.

You didn't get new tasks immediately because your computer still had work to do. Once your computer's amount of work drops below a certain level (configurable locally with the BOINC manager), your computer will request work from whatever subprojects you have enabled at that time. Right now, your computer has some PPS and SGS tasks, so everything is working properly.
6) Message boards : Generalized Fermat Prime Search : GFN Status by n-Range (17-22) (Message 141759)
Posted 17 days ago by ReggieProject donor
The leading edge on GFN20 can no longer use OCL4 and GFN21 may start failing on OCL and switching to OCL4 (automatically). The main post will be updated at some point in a week or so.

The last character on the fourth test for all of those is missing Danny. Can you confirm that the last character is "4" for each? The other three tests look good for each cell.

Here's a link to a copy on PrimeGrid's server: https://www.primegrid.com/AP27%20Testing.xlsx
I will not be updating it with reservations though.
9) Message boards : AP26 - AP27 Search : AP27 Update Testing (Message 141692)
Posted 19 days ago by ReggieProject donor
It's been a while, but we have a new version of AP27 ready to be tested! This version features a bug fix for AMD Navi GPUs, CPU multithreading, CPU AVX-512dq support, and optimizations for all platforms, all thanks to the developer mfl0p.

A testing spreadsheet with links to the software is located here: https://docs.google.com/spreadsheets/d/1NpxpXYcho8nYApC2NvM-wcQtclbXS9aErv_KaNUaW8E/edit#gid=0. Only 64bit operating systems will be supported. To reserve a cell, make a post here. Run the four test cases and post the contents of SOL-AP26.txt here for each.

For CPU test cases, be sure the software detects the correct type of CPU when it starts. It will output something like "Detected avx2 CPU". Make sure this matches the cell you reserve.

For multithreaded CPU tests, append "-t #" (without quotes) to the command line arguments where "#" is the number of cores you want to run. The number of cores is up to you, between 2 and 64.

Once all testing is complete, you will be awarded PSA credit equal to 20% of an AP27 workunit for every cell you reserved.
10) Message boards : Proth Prime Search : Exact difference between PPS, PPSE and MEGA (Message 141527)
Posted 26 days ago by ReggieProject donor
I'm quite sure this was answered somewhere, but I can't find it.

From the stats page it looks like all PPS and MEGA are searching the same k's and similar max values for n. Is the whole range from 0 < n < 3.xM sieved and then MEGA checks larger n while PPS check smaller ones?

What is the exact range of n and is it completely covered?

PPSE appears to seach larger k exclusively?

PPS is for odd k's in 4<k<1200. PPSE is for odd k's in 1200<k<10000. PPS-MEGA started searching with PPS k's but was moved to PPSE k's a little while back. Select k's are also being searched in the PPS-DIV subproject right now at higher n values. I'm 99% sure the search started at n=10k, but I don't have a source handy for that.

Sieving is complete for 0<n<6M and undergoing for 6M<n<9M. This is being done through the PPS-Sieve subproject.

The stats pages aren't ideal for this information since it doesn't show gaps between PPS/PPSE and MEGA.
