Acoustic Opti Apps

Right, but don't forget Intel SSE2 versus AMD SSE2 isn't always comparing apples to apples.

Well that's certainly true. The Threadripper's AVX2 performance on tight code like SRBase and PG sucks in comparison to Intel's.

Windows is about 4.3% faster than Linux but that is much better than the 35% of the stock apps. They greatly improved the efficiency of the Linux app. My 2990WX w/ AVX2 got over 3X reduction in time per WU on Linux. It went from 4400s (WU from a month ago) to 1280s now!

Confirmed in fact a LOT better than initially shown.....
31-32 minutes a WU!!!!! seems to be what they are leveling out at.....

Almost 3x faster......

So, much of the subset of my Linux fleet that's running has managed to turn in at least 10 WU's with the Opti app. Looks pretty good. The best improvement was for a VM running on an Intel Xeon X5672, which has averaged 2574 seconds per WU for it's last 10 Acoustic WU's. The ones that are lagging seem to be the ones that have been running WCG alongside, and it's mainly because the TB WU's taking over 16 hours to complete have prevented Acoustic from getting 10 WU's through yet.

Worst is on an AMD 6220 guest that's taking 5454 seconds per, but is understandable considering the host is oversubscribed by a bit too much. (22 Virtual cores running on a 16 core host) But basically, everything is taking between 32% to 44% of the time they used to require per WU.

I still won't manage to keep up with Bowmore for the next two weeks, but once I start hitting my goals on Rakesearch and DHEP, I'll have a few more cores to shift over.

I'm glad those new apps helped the Opterons! That'll make your jaunt to 100M easier. The guy in 2nd place hasn't upgraded to the new apps yet.

Rumor has it that Bowmore will retire in about 4 days when he gets to 10M.

Rather than helping get Seti USA to 100 Mil that much sooner.

Oh no, not a guilt trip Alright I'll add 3M to the SUSA coffers and then I'm pulling the plug. 10M is enough for us mere mortals.

HEADS UP - I'm getting a lot of errors on downloads on every machine. When that happens the BOINC client goes into a 24 hour backoff. So check your machines.

I looked at a number of computers on the Top Computer page and they are also getting download errors so it isn't just my machines having problems.

so says the geek with 27 projects over 25 m.

Oh yeah, I forgot about those! Actually the problem is my ADD. I have a hard time leaving the machines alone and sitting on a project for extended periods of time. It would take me 3 weeks to hit 25M on Acoustics and with my memory I would forget what I was doing long before that time was up
