TBar - Are you going to do an SSE41 optimized version of v8 like you did for v7?

I've been testing one for a few days, http://setiathome.berkeley.edu/result.php?resultid=4646145743
It's a little slower than the v7 App though, I was hoping to speed it up a little. It's still faster than the stock version on my machine though.

Will it take advantage of AVX2 in addition to AVX? In my own benchmarking, it can be up to a 90+% increase in speed.

No, not at this time.
AVX just gives a little improvement.

A little is better than none, and all modern CPUs since Sandy Bridge have it.

I posted the general outline of the plans in the Panic Mode On (101) Server Problems? thread a couple of days ago. It's possible that Eric may catch me out by transferring the apps early in his working day, rather than waiting until I'm on my way to bed - and I won't know until I see them whether the prepared installer is ready to release without modification. We'll have to play it by ear.

Yes, I have been provided with AVX versions of the applications, but none of our developers have moved on to AVX2 yet.

Not all of our volunteers here can afford to buy the latest hardware on release, so we cater for a wider range of CPUs than just Sandy Bridge - or just Intel, come to that.

Of the very few "results returned in the last hour" only 10% are v8 cpu results.
It used to be around 80000 for version 7 total ( inluding GPU).
The applications site lists about 250,000 GigaFOPS for windows v8.
How can it be, that only about 200 results are returned per hour,but lists this enormous gigaflop count?

Holy cow, I just saw Petri33's cuda 7.5 result times. I assume this is due to his custom optimizations for the latest (Maxwell and up?) GPU's? That's incredible its that much faster, hopefully we'll all see the fruit of that labor once we get the stock apps out. My 750ti's might start making some noise. lol

Most definitely :) A raft of Perti's work to integrate as baseline v8 proves itself for the compatibility/reliability aspects. Some things to nut out about how to allow performance code without sacrifices in other areas, after all I'd like to have my cake and eat it too. What we'll mostly be looking at is how to best to make it run for your specific needs (for example some may have plenty of CPU to feed that kindof throughput). Other's might want to crunch light while playign Xcom long war and youtube videos. Probably will end up like some small gui with a throttle, and some limited automation capability, since deploying apps with fire extinguishers probably isn't practical, lol.

Not quite yet - I've just logged an inconclusive against one of his testers with the latest x41p_zi

But it was an extremely early overflow (~3 seconds), which we don't worry about too much.

Yeah, from what I've last seen (a day ago due to dust bunny cleanout time here) it's getting close for high end dedicated crunching, testing many features I haven't had the chance to yet. alpha staging area for the code is in place (along with a raft of slots for x42 work after that). Probably early performance betas will need to be decent systems/newer GPUs etc, though eventually enough bits will fall into place to be flexible enough for stock (optimised releases somewhere in between).

Do me a favor and read the server page properly.
COMBINED!
That is why v7 and v8 always read the same.

Judging by the number of v8 (alone) 'out in the field' and 'waiting for db purging', I really don't trust those "combined" figures - especially turnaround, which is nowhere near a week and a half for v8.

I suspect the combined figures are, in reality, v7 only.
