PrimeGrid Year of the Rat Challenge March 12th 06:00 UTC to March 17th 06:00 UTC 5 days PGs challenge thread at their webpage http://www.primegrid.com/forum_thread.php?id=9063 This is a CPU project, SR5 LLR for 5 days CPUs with FMA3, AVX, AVX2 and better yet AVX512 would run the fastest. Multithread will work on this project. MT can be setup with the app_config file or setup right on the PG preference page. No bunkering, only tasks DL after the start and turned in before the end count towards the challenge. This is LLR and uses AVX.xx FMA3 so the CPU temps may be on the warm side, so watch the overclocks and temps. Clean out the dust bunnies before the start. If overclocking, make sure the system is stable so the task does not error out. Good luck everyone. SR5 primes are out there and can be found, so getting one is not out of the question.

This will run in direct conflict with the first Formula Boinc Sprint of the year. Let’s hope for a GPU project there.

Gotta love what a 9800x with AVX 512 can do all by itself. Add some misc. computers and a few AVX 512 cloud cpus and you can churn out some units. I'm eying an i-9 10 series if they ever ship... 18 cores of AVX 512...

Ohh, I found a Prime. Dear Primefinder, Congratulations! Our records indicate that a computer registered by you has found a unique prime number. This computer is running BOINC, is attached to the PrimeGrid project, and is assigned to the Sierpinski/Riesel Base 5 Problem. What makes this prime unique is that it's large enough to enter the Top 5000 List in Chris Caldwell's The Largest Known Primes Database. Since you have auto-reporting selected, the following prime was submitted on your behalf: Added 130771 : 238694*5^2979422-1 (2082532 digits) This prime was found on this workunit which will automatically show as a prime result after verification by the Largest Known Primes Database. If you have any questions or concerns, please contact us and we will surely resolve any problems. Once again, congratulations on your find! Thank you for participating in PrimeGrid. PrimeGrid staff

Congratulations!!!! I saw in the PG thread that someone found a prime. So glad it was someone on the team. Nice large prime at that; just over 2 million digits long.

Thank you!
This is only my second prime and it is much larger then the first I found back in 2015. The 2015 find was Decimal Digits:388,341. This new ones dwarfs that at Decimal Digits:2,082,532.

Another one in the books.
From the PG challenge thread.
Here are the final stats for the challenge, incredible job everybody! We managed to find TWO SR5 primes during this challenge, for a record total of FOUR THIS MONTH!
Cleanup is starting, it will likely take about 4-6 weeks.
Challenge: Year of the Rat
App: 19 (SR5-LLR)
(As of 2020-03-17 14:30:11 UTC)
143767 tasks have been sent out. [CPU/GPU/anonymous_platform: 143695 (100%) / 0 (0%) / 72 (0%)]
Of those tasks that have been sent out:
10131 (7%) were aborted. [10131 (7%) / 0 (0%) / 0 (0%)]
945 (1%) came back with some kind of an error. [945 (1%) / 0 (0%) / 0 (0%)]
119453 (83%) have returned a successful result. [119382 (83%) / 0 (0%) / 71 (0%)]
9523 (7%) are still in progress. [9523 (7%) / 0 (0%) / 0 (0%)]
Of the tasks that have been returned successfully:
8957 (7%) are pending validation. [8955 (7%) / 0 (0%) / 2 (0%)]
110057 (92%) have been successfully validated. [109988 (92%) / 0 (0%) / 69 (0%)]
395 (0%) were invalid. [395 (0%) / 0 (0%) / 0 (0%)]
44 (0%) are inconclusive. [44 (0%) / 0 (0%) / 0 (0%)]
The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is n=3064654. The leading edge was at n=2968224 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 3.25% as much as it had prior to the challenge!
