Is the best way to determine run times to disable networking and view the finished WUs, then?
I thought so, but there's plenty of tricks that I have yet to learn!That's what I'm doing. That's about all we can do, right?
My Ryzen is running pretty fast now, but I can't tell you the times, but the units are disappearing from the queue pretty good now.I thought so, but there's plenty of tricks that I have yet to learn!
I've meant to ask you, how did you determine that SMT needed to be disabled on your AMD chip(s)? I didn't have time to test both ways.
It's one way. Though you need to be there to control the supply of tasks.Is the best way to determine run times to disable networking and view the finished WUs, then?

I've turned off SMT on one of my Ryzens (1700 PRO) as well. I have some data on how it does with it on, and it's not encouraging.I didn't know. It's just a test.

Well, I would think that the completion times would need to be less than half with SMT off for there to be an advantage, all else equal. I'll know by the end of the day how SMT OFF is working out on the 1700 PRO.That's consistent with the data I have too. It's better with SMT on.
Are you really driving all 6 cores under AVX load at 4.7 GHz? (If so, didn't the TIM vaporize by now?) ;-)i7-8700K @ 4.7GHz, HT ON, 4 threads, avg of 4 WUs: 10,320 sec.

Assuming an average of 1,690 credits/task and 3 tasks running in parallel, this makes a host throughput of
1,690 credits/task * 3 tasks * 24 h/d * 3,600 s/h / 10,320 s = 42,450 credits/day.
i7-7700K @ 4.2GHz, HT ON, 7 threads/task (leaving one thread for background stuff such as SZTAKI):
2,937 s for a 1,678 credits task
1,678 * 1 * 24 * 3,600 / 2,937 = 49,360 credits/day
I have not tested two tasks at a time on the i7 with SR5-LLR. Butin my tests with one or another longer running LLR subprojects I saw the 4C/8T Haswells and Kaby Lakes perform best with only one task at a time.
--- Edit: Wait, I did test SR5-LLR with 2 tasks at a time, 4 threads/task. It gave 44,020 credits/day for the i7-7700K host.
Either your setting of 3 tasks on socket 1151 is quite a bit off from Coffee Lake's optimum, or/and you have some phantom throttling going on (on a moderate level).
Ah, that's different then.It's delidded
OK, this additional I/O load on the processor is certainly among the reasons why your CFL puts out a little less SR5-LLR than my KBL. Finding optimum PrimeGrid settings when running concurrently with a defined GPU load opens up a whole other branch to research...I am running Amicable numbers on the 1070ti concurrently,
Hmm. 1 task/socket may not be the best advice for a 6C/12T CPU anymore, since there is no good scaling past 6 or 8 threads per task to be expected in SR5-LLR. So, maybe 2 tasks at a time, 5 threads per task for PrimeGrid, and the rest for Amicable and the system?Any suggestions on config modifications would be much appreciated!
Done, and perhaps I should do similarly to all the rest which are running GPU tasks, since the drag of the GPU probably makes my CPU performance data pretty useless. I was just going for maximum throughput by trying to use all threads for SR5....So, maybe 2 tasks at a time, 5 threads per task for PrimeGrid, and the rest for Amicable and the system?
Our new leet acronym is catching on.We will become 7AA7 quite soon.

1 __ Czech National Team ____ 3,081,257.94
2 __ SETI.Germany ___________ 2,958,538.30
3 __ Aggie The Pew __________ 2,597,659.52

8 __ Crunching@EVGA ________ 589,799.54
9 __ BOINC@AUSTRALIA _____ 409,316.34
For 18 hours we were able to hold our lead after the first delivered WUs, until the Czech National Team passed us, and even pulled away a little bit in the meantime. Once again, Aggie The Pew takes a bit longer to get going, but we know the game well enough. Behind them, 7AA7 moves on an unfamiliar rank, which seems relatively safe as S* presents itself very weak. The trio who contend for sixth place, with slight advantage for BOINC@Poland, runs the risk of being skipped by a kangaroo.
See my updated result, you may find it more consistent with expectations. Apparently over-allocating can do more harm than good.@crashtech, I just remembered another potential factor: My 7700K is run by Linux, which generally keeps quiet and lets applications do their work. Your 8700K is run by Windows, which may have background stuff enabled that MS deems worthy of your processors' frequent attention...
Guessing 1,600...1,700 credits/task, that would be 59...63 kPPD. Now that's better!See my updated result, you may find it more consistent with expectations.
LLR being AVX and cache/memory intensive, combined with PrimeGrid using fixed credit, over-allocation should be bad, agreed.Apparently over-allocating can do more harm than good.
You should turn SMT back on, the advice to have it off apparently applies mostly to older Intel CPUs. Can you post your app_config.xml? Did you restart the client after making changes to app_config.xml?My Ryzen 1600 jumped to completing tasks in... around 18 hours. With SMT off and the app_config.xml change. There was one task that had been running for 21 hours and had not completed yet. I may be having a slight problem. Have I configured something wrong?
