Martin Gardner's Birthday Challenge Oct 21-28 00:00:00 UTC  GCW-LLR 7 days
 
Challenge thread: http://www.primegrid.com/...ead.php?id=9767#151710
 
This is a CPU challenge LLR2 so you will be first for prime finder.
There will be some short validation tasks to do.
Clean out those dust bunnies, these tasks can run warm using AVX FMA3.
 
No bunkering, only tasks DL after the start and UL before it ends will count.
 

The PG challenge thread is up.

With testing today I got this on one of my Tasks, anyone know what this might mean?

My Task on an i7 5960x eight core at 4ghz
Took 7 hr and 36 min.

The task sizes vary so times for each task will not be the same

Great, thanks.
I will get that changed.

On an i9-9900k 8 core MT it is doing about 18 to 18.3% per hr.
I est. around 5.5 hr. Not sure what the FFT size is 1792.
 
It ended up at 22,586.63 sec = 6hr 12min roughly

All ready to go.  Thanks for the test data.

GPU, Good News!

If you are also running Collatz Conjecture 10/21/2021 08:00 (UTC) - 10/24/2021 07:59 (UTC)
You need to Keep the Network Alive so that PG can send updates on your PG Tasks while it is running.
If it crashes it will start back up ONLY if your updates are being uploaded.
Sad News for Collatz Conjecture running Formula Boinc 2021 that is you cannot dump your tasks after start time without losing a PG Task.
If I have this all wrong Please Correct this Post......

Great, I wanted to be sure on this one.
I did just dump my two rigs that are not running PG.
I am going to add one more this morning and one tonight or tomorrow morning being I do not want to dump any WCG Tasks.

blah - couldn't even add Collatz 

Moved up to 9th from 12th, good job. 
Will see if we can hole it.
 
6 days down, one to go!

0 (0%) are inconclusive. [0 (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=6347216. The leading edge was at n=5844056 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 8.61% as much as it had prior to the challenge!

Any-hoot, Glad to see the Team back in the Top 10.
I would think that with AP coming up in the Next Challenge we should do very well.
