Good luck to everyone for a lucky hit of a TOP5000 prime maybe solving a base with CPU or running Trial Factoring with GPU.

Welcome to all of our new users. Before you start take a look into the FAQ section.

There will be 2 times a day a short outage for backing up the database. You will have enough work in this time. The max_wus_in_progress for CPU is 50 per core and 80 for GPU.

Trial Factoring 72-73 range reached
The first 100k batch is uploading in the 100M range for 72-73bit. After the server load is reduced by finishing the last 900M range batch there will be more work. Pls note there was a typo of the batch 886-994M batch, must be 886-934M.

Take care of the runtimes. The latest 72-73 batch need around 24min on a RT5500XT, this is a factor 16 from the last 71-72 batch with around 1min30s.
