Hello folks,
Is the video card memory speed improtant for Einstein BRP5 WUs or is it like it was when we crunch ATI hcc1 WUs?
I had a rig running 2 X AMD crossfire 7970s at 1010 / 1375 which I have switched to 1010 / 900 without any apparant drawbacks.
Also what amount of GPU utilization are you guys getting? My GPU utilization with 2 WUs per card is in the 55 - 70% range. I am tempted to add one more WU to each video card but everytrhing I have read says stick to two Einstein WUs max per card? What do you think?
My 7870s run at 80% with 2 WUs. While most seem to say more than 2 shows no advantage it would not hurt to try. The 7970 is power house.
Everyone says you need 1 core per WU. I tried it in the past and saw no difference. Tried it again with different hardware, let 4 GPUs on 2 machines have 2 cores per GPU. After 3 days no difference to speak of. Back to .5 core per WU. WCG needs the cores and no benefit for E@H on my setups. Why my GPUs do not see the difference I do not know. I know the people saying 1 core per WU know what they are talking about. :shrug:
From what I understand memory clocks are the least important on E@H. I read to OC everything else and when at max then up the memory. If you reduced it and saw no difference other things are probably what is holding your GPU back.
A lot depends on the chip set. On the projects #1 top host I'm running five BRP5 Wu's/7970 getting 98% usage. Motherboard is MSi big bang2. I've found the BRP4G app better on my older rigs.
Thanks PG, I am also sticking to 0.5 CPU per Einstein GPU WUs for now. I have also noticed something that puzzles me. The 3930K CPU that I have runs at 4500 MHz and the 2600K CPU at 3800 MHz. When I compare the actual CPU time needed to complete a BRP5 WU, they both range between 1,300 to 1,450 secs. The GPU runtime for the 3930K is 10,600 to 10,800 secs while the GPU runtime for the 2600K is 18,200 tto 19,600 secs. Do Einstein @ Home WUs use the CPU througout the whole GPU WU processing rather than at the start and end like hcc1 WUs did?Quote:

I can only say that I saw significant performance difference when CPU threads were saturated while running BRP tasks. Thus freeing additional CPU core(s) has helped much.
You can make a simple test: watch the CPU usage of BRP tasks while running different amount of other CPU tasks - suspend them all, then resume one by one.
Once you get to a point where the CPU usage of the GPU task starts to drop, you know the CPU is saturated and that is going to hurt your GPU WU performance.
I'm using BoincTasks which shows this, you might also use other tools.
The point I was trying to make, and did not do a good job of doing, is to experiment a little as your results may vary. My systems seem to have a bottleneck. Not too worried as WCG is important to me. I not unhappy with what I am getting, even if it could be better.

Thanks a lot Mumak, I will use your above procedure to fine tuned my 2600K rig and find its Einstein GPU vs WCG CPU sweet spot. I am like PG and favor WCG work over Einstein work but I cannot let two 7970 GPUs crunch at only 50-60% of their potential. :up:Quote:

Einstein@Home will be shout down tomorrow (Wednesday Oct 8) morning (CEST) to perform some urgently necessary database work. We expect this to take a couple of hours.
Top 20 hosts for E@H.
A familiar name is listed a few times. ;)

After project 'maintenance' today I had the usual scheduler URL updating fiasco, resulting in 50% of my hosts running dry. Always happens when I'm not about to do it manually :mad: FFS get it sorted Berkley :shakes:
Thanks for the Post Sam, My rigs were found crunching away at their 3 days Einstein WUs cache with a 3-4 hours communication deferred message in the Status of the Einstein Project. Did a manual update and downloaded a whole bunch of new Einstein WUs.Quote:

They have changed the URL on server, so the BOINC client needs to fetch the new one. This is done automatically by BOINC after ~10 failed accesses. You can speed it up by pressing the Update project a few times in case your results didn't upload/report.

:eek: Hopefully just an accounting blip after the outage & normal service will soon be resumed :yepp:
....having said that I've migrated some cards back to GPUgrid so totals will be a little lower from now on :(
Hmm.. "a little"...
Looks like we need to get back some of our inactive members to pick up the slack and keep us on top of the heap.
We will likely all reduce our Einstein production due to the forthcoming XS WCG SC week in mid-November.

10 more days & we should gain a place, followed soon after by further gains http://i602.photobucket.com/albums/t...b/0b8b5aaf.gif
Looks like temps are to stay in the 60s-70s so I brought up a few more GPUs. Nothing too new or too powerful but enough to be an aggravation to those that like key lime pie. :D
That's the spirit PG :clap:

Sam,
I love your new night sky background for the Einstein Stats. Looks cool and very well suited.
I am going to wind down my Einstein contribution over the next couple days to concentrate all my available crunching resources on helping the XS WCG Team with the fortcoming WCG 10 year challenge.
I will be back around ~ 26 Nov 2014 :D
