11) Message boards : Number crunching : Makar Sankranti Challenge (Message 91038)

Care to share? Especially if you have something for Linux and Nvidia?


Hello,

I only found the dedicated PrimeGrid forum, but no app_info for my config.

I will maybe switch 2*970 -> 2*HD7950 ...

Best, Phil1966

Hello !

Currently running the challenge on/with 4 * GTX970.

Where can I find the app_info stated in Michael's message ? "Nvidia Maxwell GPUs may benefit from using app_info to run OCL3 instead of OCL on GFN-21 and 22."

Will the WU's run as fast as with ie a HD7950 ?

THANK YOU

Phil1966



Found (almost) the answer.

Thank you for your help.

I am currently running a "test".

4770K HT OFF / turbo speed 3.9 Ghz / Temp 50 ° C / 24 Go RAM @ 1600 / Z87 PRO / WC AIO

Running only 1 single WU (=> 1 core only) looks very fast. (less than 4 hours)

Running 2 WU / 2 cores looks ... fast also (less than 4 hours)

What I don't understand is why running 1 instance of "4-quad-start-prpclient" is slowing down so much the cpu performance ... (it needs at least 12/14 hours to run 4 WU's at a time, 1 per core)

Running 1 WU on 1 CORE or 4 WU's on 1 core each = 4 cores should not (as far as I understand ?) increase the calculation time by 400 % ...

Something not logical I cannot understand.

CPU load running 1 WU = between 25 % and 27 %
CPU load running 2 WU = between 49 % and 55 %


NB Can it be a RAM problem ? I see it uses 3.25 GO when 1 wu running, but same 3.25 GO when 4 wu's running ?

NB2 Have set the Priority to 1 = Normal

Thank You

Best Regards

I know ...

But look at the previous posts :/

It tooks 18 hours to complete 4 WU's, HT OFF.

I prefer to quit rather to bother people with running times.

Thank You

Best Regards

Philippe

Thank you for your responses.

I ran : pfgwexe=pfgw64.exe, but it took really too long (as far as I understand) to complete the WU's.

18 hours HT OFF on an i7 4770K / WC AIO running @ 3.9 Ghz / Temp 49° C ...

Maybe I did something wrong :/

Thank You for your help.

Best Regards

Philippe

EDIT : I'll try 6 WU's on the 4770K, HT ON, @4.3 Ghz, running pfgwexe=pfgw64.exe (= for 64 bits OS, right ?)

Best,

Phil

Hello Again,

Sorry to bother you, but is there a way to improve a little the WU's running time ?

Even HT OFF, it tooks 18 hours to complete on my i7 4770K, and about 19 hours on
i7 4700HQ HT ON ...

Is there a setting I can amend as for the GPU WU's ?

NB @Sysadm@Nbg : My running time look really far too long when compared to yours ?

NB2 using pfgwexe, not llr.

Thank You

Have a nice week end

Hello !

Thank you for your answers.

My CPU's = i7 4770K @ 3.9 Ghz / i7 4700HQ @ 3.17 Ghz

Both HT ON

It looks like it will take about 20 hours per WU ... ?

Wait and see :)

Hello,

Is it better to have 8 cores crunching 1 WU or 8 cores / 8 WU's ?

If yes, can you explain me how to have 8 cores / 1 WU only ?

Thank You

If I understand correctly the stats, one was allowed to start before today 2:00 PM,
not like "usual" PG challenges ?

Finally, what is the average running time of 1 WU ?

Thank You

Best Regards

Philippe
