Prime Grid won both the CPU and GPU elections. We start right off with the Double Top Secret Mystery Challenge, beginning Saturday March 1 at 1:00 p.m. EST U.S. Adjust your PG account to download CPU WU's only for the Prime Sierpinski Problem (LLR). Pick whatever PG projects you want for GPU.

All my CPUs, GPUs and ARMs are on PG for the month. I will be participating in the CPU challege on PSP (edited) sometime after the start as I will be watching a movie in a theater when it starts (taking godson to a premier), but should get it started within a couple of hours. For GPU I am running PPS Sieve on ATI, GFR-WR on NVidia and TRP Sieve on ARM. All these project will help get my first start on WUProp a little closer to Magenta 10000 hours).

Currently I have 11 at Magenta or higher, I should get 2 of the above to get there by the end of month, plus 1 PG not in the above list. Then I need to move to other projects for the other 7.

WUProp is somewhat hard when projects fall off. Like now only Solo Collatz and the other two are gone. Weird Engine and ALX from OProject are currently mostly defunct, any Pirates ones would be near impossible to get thousands of hours on without an army of computers, etc.

Oh well, all the fun. Good luck on the PotM and the challenge if you decide to participate.

I'll be adding my 1¼¢ to the CPU p.o.t.m. by starting the Double Top Secret Mystery Challenge on Prime Sierpinski Problem (LLR) on 3 cores.
I'll finish out the month on Prime Grid with other easier WU's.
I hope this helps a little. «°¿°»

Any idea what is the name of PPS (Sieve) AMD/ATI/OpenCL GPGPU Windoze application I can use in app_config in <name></name> tag?

Thanks in advance #ni-2

Yes, mine either. But utilization is only approximately 70%, so I want to try 2 or 3 concurrent.

Guess it would be something like PPS_Sieve ?

ETA: it is pps_sr2sieve #ni-1

With 2 concurrent (HD 7750), utilization is 94%

With 3 concurrent it is 97-98%

The challenge has started! Currently running 8 WU's HT AEEA (Hyper-Threaded, Against Expert Engineering Advice), 204 hours estimated completion time. If that's accurate, I'll only be able to run one batch.

running only 3 cores of Prime Sierpinski Problem (LLR) 6.15
Time Remaining on each = 410 hours 2 minutes 32 seconds Shocked

I shall have to feed the Computer Hamsters "Extra Energy Formula Hamster Chow". Rolling Eyes

Edit: I'm getting a little less than 1% progress per hour of elapsed on each WU... I hope that will mean that each one will only take around 120 hours.

Turn the hyper threading off or at least set boinc to 50%. Hyper threading more than doubles comp with LLRs. Is bad for shrubbing!

Drat, how do I turn off HT? Assume go to Boinc preferences and set "On multiprocessor systems use at most 50% of the processors"? Is that better than setting PG project useage to 50?

You can turn HT off in BIOS, but I do not recommend it (Never fix what ain't broken).

Setting 50% in BOINC prefs is the easiest and safest way Wink

Setting Boinc at 50% will get you almost as much as turning hyper threading off. And much easier to do, especially if you aren't used to pillaging your bios.

I set it to "On multiprocessor systems use at most 50% of the processors". Shrubbing only 4 at a time now, but estimated total time doesn't seem to be decreasing.

Ooops forgot this:

Starting Stats:
12th Place
4,432,728,436 Total points
3,094,571 average daily production past week

Estimated times are really just estimated. They may change later, but the best way to do your own estimation is: (already) elapsed time of the task / percentage of competition of that task #ni-2

12.9 hours / 18.8% = 68.6 hours. Wow, much better - Thanks!
After all this time, still a #Newbie

Mine example:

- est time for 3 downloaded WU's on my 4-core (non-HT) i5-2500S Sandy Bridge (@ Max OS X 10.9.2): 79 hours
- 85,6% of the first one completed, elapsed time 46 hours, 21 mins (running one PG + 3 WCG MCM1's)
=> my est time is 54 hours. Much better than BOINC's estimation. But not that better as yours LD Cool

Don't worry about estimations, just keep shrubbing #ni-1
