1) Message boards : Number crunching : So time it takes to run SGS (Message 108606)
Posted 1686 days ago by kiska
I can't speak for the older Core 2 based Xeons (I retired mine years ago), but your e3 and e5 times look like you're running every thread. On LLR, you want to either turn off HyperThreading or set Boinc to use only 50% of cores. Your 2670 should run around 1.1-1.2ks/task (assuming you are properly cooled and there is no thermal throttling) and the 1230 even less than that (700-800).

Also, I see you have a super large number of cached tasks. Around here, setting boinc to 0 day cache=more chance of being primary prime finder.


My 2670 is my heater :P
My 1230v3 is running with 5 threads, but I didn't think it would affect times by 100+ seconds

Also my workstation was running s@h for the past 3 weeks, so it has to "repay" debt to PG, so it downloads tons of tasks even though I have set 0.01 + 0.05

So my X3323 is completing these in ~2.8k seconds, the e3-1230v3 is completing these in ~1k seconds, my dual L5420 is completing these in ~2.2k seconds and my workstation e5-2670v1's are completing them between 2k and 2.6k seconds.
So are these times normal, or is there something I need to do. My PCs are viewable if you want to see the times
3) Message boards : Sophie Germain Prime Search : 4888 (Message 108600)

I am going to say end of June, so my guess is 30 June.
I have noticed my team's prime for the challenge enter in position 4901 and now its at 4911, so it won't be long now...

5) Message boards : Number crunching : Cards targeted at cryptocurrency mining? May be good for primegrid too! (Message 108478)
Posted 1690 days ago by kiska
I guess I'll cross post from S@H on what I said about this topic: https://setiathome.berkeley.edu/forum_thread.php?id=81495&postid=1872161

So ethereum one of the currencies blowing up, is anti-ASIC, the algorithm was designed to be memory IO intensive. If it was CPU bound, then designing an ASIC would be fine, but its not its memory, and ASICs do not improve memory IO.
Another thing is that these "cards" or "systems" is designed or rumored to be designed on the GP106 chip, which is the chip that powers the 1060, so I expect with power efficiency in mind, these will be clocked lower but keep almost all of the features, well besides the display

Also the algorithm favours the AMD cards, we have a shortage of RX 400 and 500 series cards, with the last value I heard of for the RX 580 going for $900
6) Message boards : Problems and Help : Server not accepting requests from host? (Message 106885)

Hey, I got this in my event messages:

444470 PrimeGrid 13/04/2017 1:20:27 PM Not accepting requests from this host

What is this about? Previously I was able to get work on this machine, but as of recently I am unable to

Short answer: I banned four of your hosts.

Longer answer: There are more than the normal amount of malfunctioning hosts running TRP Sieve jobs. They had been so "productive" that we had a half-million results that errored out in about 3 seconds, at which point the host would grab another task. So, for any computer that showed 50 or more TRP Sieve results that ran but errored out in less than 10 seconds, I've blacklisted that host. I haven't been looking closely at who I banned, figuring that anyone who was a normal user would eventually notice and say something.

Running a quick query, your hosts 610371, 610487, 613080 and 613537 are among the 1690 total hosts banned. I'm allowing them again, but if they get above 50 TRP Sieve tasks where they show a nonzero runtime but the task errored out, they'll automatically get banned again. I don't have the ability to ban by subproject, it's an all or none setting.

As to why I started doing this - we were getting into trouble on the database. The result table had grown so large that queries were taking too long. It was still manageable, but we couldn't let it get any worse. If you look on the Server Status page at the strip chart right below Filesystems, you can see how we had 3.5 million results and that's now dropped to under 3 million. That makes a huge difference in how well the system works.

I apologize for the inconvenience to you, but we had single hosts with 70,000 bad results apiece. Most had errors where they couldn't download the sieving program and so were never going to work. I had to pick a threshold and chose 50 bad results. You're the first one to notice and say anything about it. Chances are I'll unban all the hosts after TRP Sieve is completed so that nobody else is in this situation.


I figured that problem had something to do with my issue, but evidently I forgot who to contact about it

Short answer: I aborted tasks for a challenge

What is the current expected timeline now?(How long left)

Whoops, I meant candidates. Well that shows my tiredness, its 11pm now. So how long left before the sieve reaches optimal depth?

Posted 1781 days ago by kiska
I see on the status page, we're upto 83P, so what is the sieving depth that we are doing for TRP again?


Our most recent estimate is 206.


And where are we at for LLR?
