My 750k genefer that sat in Inconclusive for a week was marked Invalid. Ouch.

Ouch indeed

You are hammering up the points for today though [mention]poppageek[/mention] - much appreciated. This table auto-updates

I had a Feeling Lucky? work unit go valid for 944k. So won't be a normal day.

[mention]poppageek[/mention] you inspired me to try some big WU

Just got paid 706K for a Genefer22 but I see my slower CPU and slower GPU meant it took twice as long as the other guy https://www.primegrid.com/workunit.php?wuid=604676133

PG does best if you turn off hyper threading. It is very tight code.

Ah thank you, I do remember seeing that somewhere before. I'll put it in the forum header box

Hmmm - Rather than lose 32 threads turning off hyperthreading on my Threadripper, I think I'll reconfigure to run PrimeGrid on something else. I have a Xeon(R) CPU E5-2609 v3 which can't HT but that only runs at 1.90GHz.

Seems like a Pentium with many MHz and not many cores would be the ideal CPU to drive 3 nVidia cards on PrimeGrid

I may be mistaken but I think PG will use AVX2 if the machine has that capability.

Pretty smart stuff this PG. I'll put another 1080 on the E5-2609 v3 and see how it works out

Thank you

Landed a 944K WU from the gtx1660ti last night https://www.primegrid.com/workunit.php?wuid=606226087

Took 50 hours given the rather modest GPU / CPU involved (HT is on). My wingman was just under half that time on superior kit

My comments were based on running it on CPU. If you are just doing GPU then HT makes no difference.

Ah - I misunderstood. I thought you were referring to the (not inconsiderable amount of) code which still ran on the CPU to keep the GPU busy

While I have very little interest in Prime numbers I think Prime Grid is the most interesting and well done project and web site of any I have participated. I'm off it now but plan on returning sometime this fall. Summer heat means much fewer crunchers. Sad times.

If you have CPU cores that you can keep cool the Generalized Cullen Woodall Sieve pays well for a CPU app and you can also earn a sub-project badge. That sub-project is going to shut down May 1st I think so get it while you can.

They recently revived the 321 Sieve app and it pays even better on CPU. Not sure how long it remain active.

You guys got me thinking PG again. I'd like to get in on that GCW work units but I am trying to get my 100 year on MCM on WCG. Only 4 more years, about 20-25 days _IF_ I can keep up current RAC. It is already hitting 80f or 27c here some days. I have shut down most of my GPUs on E@H to free up CPU cores. But IIRC some of PG GPU work units use very little CPU. So I put a 1080 and RX 570 on PG and will filter out the work units that use a lot of CPU.

We often have to shut down some of the machines during the afternoon and evening but roughly 18 hours a day is not too bad. More than nuthin' according to my calculations.

Hope all are doing well! Cheers!
