Welcome to International Cat Day Challenge: 5 day PRS (Primorial Search) from August 8 08:08 UTC to August 13 08:08 UTC

Next month we are celebrating felines with passports. Maybe I have that wrong??? Anyway, I just want to say that the Primorial challenge IS going to happen. We expect to have Primorial running on the BOINC server by the end of July, in time for the challenge in August. Meow.

(ok, the real reason I chose the day is because it's Vriska day. and she likes the number 8.)

To participate in the challenge:
 

• Wait until the challenge timeframe starts (or set your BOINC Client download schedule accordingly), as tasks issued before the challenge will not count.
• In your PrimeGrid preferences section, select only the PRS (Primorial Search) project.

Thank you everyone to coming to our first PRS challenge!

At the Conclusion of the Challenge

When the challenge completes, we would prefer users "moving on" to finish those tasks they have downloaded, if not then please ABORT the WU's (and then UPDATE the PrimeGrid project) instead of DETACHING, RESETTING, or PAUSING.

ABORTING WU's allows them to be recycled immediately; thus a much faster "clean up" to the end of a Challenge. DETACHING, RESETTING, and PAUSING WU's causes them to remain in limbo until they EXPIRE. Therefore, we must wait until WU's expire to send them out to be completed.
