How the goal posts have changed. I remember when 450,000 RAC would put you up near 5th place. Now you MIGHT make it into 9th place.....

Not sure exactly what you mean as SETI@Home only does one work unit (WU) per CPU core at a time,, unless set to use less, these WU's run from start to finish and do not "cycle back and forth".


Could the switch tasks parameter being set too low account for the impression of "cycle back and forth"?

Part of the issue might be you are trying to crunch gpu tasks on your iGPU. Very few people have much luck doing that. It usually slows the whole system down by 50% or so.

I 2nd the request for the first 30 lines of your Boinc log after you restart Boinc.

I still have one Milkyway@home task running along one Seti@home and two Asteroids@home plus a GPU task of GPUGRID. All this on a 4 Logical processors A10-6700 CPU.
Tullio


To make life more complicated that cpu model has one floating point node for each physical node. Which means heavy computation on 2 threads on the same core runs more than a little bit slower....

I had an A10-6700 (I think) and experienced all that under Window....

In graphics and/or website design they talk about "wireframes" and now I see a REAL one :)

Just ran across a new to me "Heavy Metal" system: https://setiathome.berkeley.edu/show_host_detail.php?hostid=8819281


He hasn't connected since Oct 10th.... so he has either re-deployed the system, something broke or he is experiencing the California wind driven power outage first hand. Ummm.... his profile is in German. I don't think he is in California :)

Old favorites. When I google limericks I got this one
A wonderful bird is the pelican,
His bill will hold more than his belican,
He can take in his beak
Enough food for a week
But I'm damned if I see how the helican!

Keep a stiff upper lip everyone.

It's too bad a generator isn't there that has a natural gas feed.


If I was a teenager bedeviled by acne I could maybe keep a stiff upper zit.....







Ouch... ouch.... it wasn't THAT bad was it?

Large swaths of Northern California, including the UC Berkeley Campus, are under a Public Safety Power Shutoff due to high winds and the associated wildfire risks. Our servers are located in the campus Data Center which is protected by a high capacity UPS. We expect that our servers will remain up for the duration of the outage. Thus far Internet connectivity also remains up although this depends on factors outside of the Data Center.

But at a cost of high power consumption, it has a tpd of 180 watts and if you run something for 24/7 it can become expensive quickly.
Not to mention the poor memory access by certain cores that Tom should well know about by now (it's sorta like their old module based CPU's where a pair of cores shared a single FPU, a complete bottleneck, but on the memory access side of things in this case). ;-)

Cheers.


Both 2970wx and 2990wx have the memory bottleneck issue.
However, the 2920wx/2950wx do not. I regret not going with a 2950wx on hind sight. But it wasn't until I had that 2990wx and discovered how severe the memory bottleneck was for the processing that Seti requires that it become clear a TR 2950wx would have been the best choice.

you guys always help, me the idiot out. Thanks!!


Finding syntax errors without a compiler/verifier pointing the way is VERY hard.

I got the 2630Lv2 chips for exactly those reasons. They are very cheap, low power use, and “good enough” clock speed to run GPUs. I don’t run any CPU WUs anymore.


I am beginning to feel price sensitive about my electricity costs. If I still want to run cpu Seti tasks will the cpu still run with less power at full cpu loads? I should know by Christmas if my operations change has dropped my electricity costs enough. If not, sounds like another reasonable step while still running 2 cpus would be back-grade to a couple of 2630Lv2 chips.

Yes I am confident with fewer threads and slower cpu speeds the cpu production would drop. But would it put me into a good budget place.

I could be wrong but i see no reason to use big CPU's and very expensive MB & cases to crunch, from all i know, a single GPU will do the same (or more) work with a lot less power and cost. Ian & TBar hosts are a live prove of that.

My 2 cents.


I understand that but every once in a while I get "cpu envy" and my 2nd choice Bonic project only does cpu crunching. Just thinking about a compromise between my cpu envy and my power bill :)

Overclocked Ryzen 9 3950X outperforms 24-core 2970WX in Cinebench (It beats Intel's i9-9980XE, too).

In TechSpot’s own testing, both the 3900X and 3700X maxed out at 4.3 GHz on a 360mm AIO.
And finally, to the results. The 3950X simply obliterates AMD’s current 16-core monster, the Threadripper 2950X, scoring 24% higher. It falls a mere 10% behind the 24-core 2970WX. Overclocked to 4.3 GHz results are even more impressive as it can improve its score by 11%, pushing 1% past the 2790WX.

According to online results for the 18-core i9-9980XE, that chip can only achieve a ~3700 score at stock and ~4200 overclocked, both of which are about 200 points behind the 3950X when similarly configured.


So a TR 2950X would have to drop significantly in price to become competitive in the "bang for buck" arena.

I had some downloads that stalled after todays outage. It seems to me that suspending the Network access before the maintenance outage and then re-enabling it later was an automated work around.

My problem is I can't quite get my head around the day and start/stop times. Someone explained this once... someplace. Try again?
