    Since we have PG challenges throughout the year and the challenge we are currently having supports more than one sub project for the first time, I wanted to remind people that PG gives bonus points to certain projects based on how long/short they run and possibly how important they are to get done at the time.

    Here is the original thread on the topic: http://www.primegrid.com/forum_thread.php?id=5141#79006

    However, that thread is not up to date. To see current bonus scoring all you have to do is go to your project preferences. When you select which sub-project to run, it shows you the credit bonuses, if any, that apply to each sub-project.

    There is currently a challenge going on with the SR5 sub project. According to some numbers from our EVGA brothers http://forums.evga.com/Prime-Grids-Solar-Eclipse-2015-Challenge-m2306586.aspx, it appears to run better with HT turned on. At least with SSD's in the system as that seems to be what most of the test information they shared had. I was hoping for a wider variety of SSD and non-SSD boxes to be tested as some people seem to think that SSD's level the playing field between HT on or off.

    Funny you mentioned this. Was wondering why these WUs were taking so long as I remembered a post a in the Jersey Challenge saying "Turn HT off". I ignored it; wish I hadn't! Just turned HT off yesterday on the four quad-socket systems that are running the SR5 challenge and the difference was huge. 13+ hours down to 5:45. Now I can't help but wonder if this would have made a huge difference in the PPS/SGS challenge. :( BTW, these systems do have a simple 2XSSD RAID1, but they also have 256GB RAM. Watched the discs in Resource Monitor (not the greatest tool) and saw little activity; RAM is at 1%.

    As with everything, YMMV.... in my case killing HT is the way to go.

    Yeah.. I think there may be a lot of factors. The chips you have, the disk you have, but just as important the speed of the RAM too. I think RAM speed is more important than the Disk speed for the math projects like this. The SSD factor was one of the things I was interested in as there have been a few claims in the PG forums that their rigs performed just as well with HT on using SSD's. I have also seen some posts claim that if they limited the number of PG work units to half their threads (similar to turning HT off), that they could run other projects and not lose the efficiency at PG. So in essence gaining production elsewhere while maximizing their production at PG... I don't know how true that is, but was hoping for a lot more setups configs for the comparison. It really does go to show to run your own tests before the challenge begins.

    I'm currently re-burning in my 7970 (now with watercooling) on the Short GFN Tasks - which really are short now (5 min instead of 5 hours, so just about exactly 60x shorter). Temps are great - Card core and VRMs are 37-40C. If everything looks ok in a day or so I might try a GFN-WR and see how things go.

    PrimeGrid added the AP27 sub project not too long ago. It has GPU work units. I have not ran any yet to get much detail on performance.

    Gilthanis, you are my wingman for this SOB WU. What a coincidence!

    Still crunching albeit slowly on this rig....

    Use Intel...not AMD... that is about it. Faster RAM and over clocking may help. But they are what they are.

    Completed this WU in 7.6 days. It takes longer than I expected since I'm using this rig for other crunching too.... Now, it's your turn.

    Well... it is sitting at 81% and isn't due until the 1st of March. Depending on how often BOINC manager swaps projects... it may take all of that time to get to it. Luckily this is an Intel box. Amicable Numbers keeps taking all the threads away on a regular basis. But, I'm not too worried. Even if I miss the deadline, I will more than likely still complete it before anyone else...

    Looks like you need to make your computers visible on the project.

    Preferences for this project: PrimeGrid Preferrences

    then choose yes on:
    Should PrimeGrid show your computers on its web site? yes

    Huh. That is weird. Option is checked.

    Edit: Should say, default configuration - no app_config

    I see it now. Your PPS Sieve tasks are between 390 and 405 seconds, right now. Hopefully once you go two tasks per GPU it'll be less than double that number.

    640ish seconds now I'm seeing on your pending tasks. Nice, that is nearly 50% more ppd, with 2up in PPS Sieve.

    Just ordered two EVGA 1070ti's that I will be throwing on Genefer tasks, as I am working on a Double Silver badge in that project and have ~74million points to go. Looks like the 1070ti's are about the best performance per watt out there now, which is important to me because my electricity costs here are ridiculous. I have had to shut down all my old 280X's and GTX770's because they are no longer efficient enough to run. Have been running just my 980ti and my 1080ti, so these two new GPU's should almost double my daily output for only 360 watts of additional power.

    This card still rocks for Milkyway though in terms of PPD/W.

    It does, thanks to its awesome Double Precision performance. My 280X’s got me to 50million+ points at MW several years ago, in fact.

    I would just keep it for upcoming FB sprint :D.

    I have one 7970 that got me 20M+ on a single card in MW. I plan on keeping this old card.

    These 1070ti's have impressed me so much, I just ordered two more. They are slightly faster than my 980ti in all Primegrid GPU tasks and only use 180 watts max, compared to 250W for the 980ti. Very nice. Decided to focus back on AP27 for a bit, in order to get Emerald in that project. Will get back to Genefer after that.

    AP27 GPU WU comparison times (1 task per GPU - stock GPU/Mem clocks):

    (GPU: avg time in min:sec)

    1080ti: ~14:40
    1070ti: ~21:40
    980ti: ~24:45

    I have also noticed that running VM WU's from both LHCDev@Home and Cosmology while crunching GPU tasks slows down the GPU tasks considerably. Looks like ~6 min slower on one of my 1070ti boxes. That sucks. I hate VM projects.

    Nope, I’ve hit my goal there for now. Working on Amicable now and GPUGrid after that, so you’re safe for awhile. :D
