The bureaucratic details:
Date: 01-Apr-2020 12:00 UTC, to 04-April-2020 12:00 UTC.
Project: llrTPS (CPU only) Sophie Germains' Birthday ( she is 244 and not looking a day over 150! )
As with all PG Challenges, only workunits downloaded after the start of the challenge and completed and returned by the end of the challenge are valid (double-check validation not required).
This is the 3rd of 9 challenges this year, ( http://www.primegrid.com/challenge/challenge.php ). There will not be another PG challenge till late June.
This is an LLR project so running with HT off or at 1/2 threads is best. Unlike other LLR projects at PG, here you should almost always run just one thread/core to an SGS task. Even then tasks will take a short time (under 20 minutes to under 10 minutes with recent cpus).
This is the section of the app_config.xml file that I use for SGS on an 8-core machine: (please note the name as llrTPS not llrSGS .. no I don't know why; and that this app_config fragment is forcing a multi-thread of 1).
