It was fun back in 2000 since my first account that I somehow lost access to it.
Now it's about transitioning mankind to a new level of insight, awarness or identity.
Will we setizens ever be allowed to know what our work reveals ?

Look's like after each servicing outage the project getting worse maladies ...

Hello,
Everytime then the WU are withdrown, my crunchers encounts the same behavior: the slower & less core one, which has few WU's left to crunch, receives new WUs , before the second cruncher (faster & more cores) which is totally withdrown of CPU WUs , receive it's new batch. Also when it receivs it got first GPUs (which some are already from the previous batch) and no CPU WUs. How schould I configure it for letting more CPU WUs be downloaded in advance instead of GPUs? Every outrage I would need some 100 CPU WUs more to have the work sustained on the faster machine.

Great! They are nice work horces, I'm using them six weeks now, 115W each @ 10 cores running 3,1GHz in HT. My RAC shows 49k but according to my estimations the machine is making 53-54k a day, presumably half are CPUs, half GPUs.
Happy new 2018 !!

Again can't get WU's, and my slower cruncher got more in advance than my faster.
Also noted that total score graph climbing rate diminished by the factor of +/-two on both machines.
RAC graph seismographic behavior, looks like S@H is giving less points for the job done, than before outrage time.

Come on, my flat starting to freeze and its below zero C outside !

Hello, recently I noticed in CPU statistics, 15 Threadripper machines running 4.2 GFlops. So here is my question to X1950 owners, what is the time of standard 183.887 GFlops job on it? Also I read somewhere that AVX instruction executing speed is half on TR's , so are they worth the grand, or better keep with (wait for 8700K) Intel?

Good to hear! So according to HAL9k, I can expect to cut processing time nearly by 2. As I see your 32t host is making 30k+ RAC which match with my estimations to my current RAC.
Now I'm thinking a second 2x5675 unit for allmost a peny or go insane IvB/Hsw. Beside considering this, I know that GPU's are the answer :)
In my position heat is not a big deal; I'm on north of Poland and even now in summer my home needs some ~350W of constant heating to keep comfort. So I decided that Seti will receive the benefit of my heating issues (the only way is electricity).

Hi, curently I'm using double X5675 Westmares. I'm interested how S@H tasks would benefit from AVX or AVX2 instruction sets. Now my 3.07GHz thread takes 4h50mins to process a workunit. How long would it take on E5-26.../V2 or E5-26... V3/4, supposing the same GHz (which I know that are different)? Is it worth transiting to those processors comparing to geting a second double X5675 computer (which is times cheaper)?
