Many thanks to Petri and TBar for sharing their hard work and knowledge and to Stephen for the instruction.
I'm looking forward to building my new linux cruncher this weekend (details below). With some luck, I hope to be up and running by Monday. Thank again, all.

Regards,
scocam


New build:
Intel i7 6850k
ASUS X99-E WS
EVGA GTX 1070 (3 or 4)
Corsair Dominator Platinum 32gb
EVGA SuperNOVA 1600 G2
Water cooled GPUs/CPU

PS: the number shown as 3 or 4 against the GPU's intrigues me. Did you lose count ? :)

:)

If only I had so many gpus to lose count! I'm not sure how many gpus I'm going to rob from my other machine quite yet. I have two 1070s waiting on this build but I may borrow a 1 or 2 more from my current machine. If crunching with cuda80 is as efficient as it looks, I'll load this new build with as many gpus as I can.

. . OOoooooohhh it is! The only shortcoming I am aware of, is when confronted with lots of shorties it can tend to output a high ratio of inconclusives (about 7 to 10%) due to an as yet unresolved ecentricity in the order of outputting results. But for the most part (about 99.9%) they validate AOK. So overall the productivity justifies the app.

. . Pentium-D rig with 2 x 1060-6GB cards, under SoG between 32 and 39K, with CUDA80 and as yet not settled about 52K.
. . Core2 Duo with one low profile standard clocked 1050ti, under SoG 13K, so far with CUDA80 22K.

. . Now we all know that RAC is not consistent, and not an imperial measure of productivitty because of that, but it remains the most common available means of comparison we have. And with all it's shortcomings it speaks volumes here :)

. . And while at this point I may be a tad optimistic, if/when it gets approved for general release, we may see DA's concerns, about insufficient processing power available to the project in the broader BOINC/Seti community, evaporate. With the burgeoning population of GTX1070 and GTX1080 cards combined with this app we could see an exponential growth in crunching capacity around the globe. Heck even with humble GTX1050ti's popping up like little mushrooms we could see a massive growth.

. . Enjoy!

My 1070 was running around 73s for shorties - you definitely won't see that with SoG.

. . With my 1060s shorties, or halflings as I like to call them to differentiate them from noise bombs (which run for only a few seconds), take about 100 secs, compared to full length normal AR tasks which take about 210 to 220 seconds (hence halflings). Pretty good as far as I am concerned.

Thinking, that was actually detuned because of a card mismatch - 980 w/15 CU, 1070 w/16 CU.
Running with unroll 15 for the 980, the 1070 was only at 94% capacity.

. . An observation on using the SETI based version of BOINC and installing to /home/BOINC as opposed to using the repository version which installs to /var/lib/boinc-client and /etc/boinc-client. The rep version does nost use the identity root as I had thought, but rather creates an identity boinc for ownership of the crunching apps. But the advantage with this version is that it not only creates the daemon to launch boinc client but also creates the icon for boinc manager on the launch bar allowing you to lock it there and use it to launch manager whenever you require it. With the "preferred" version which makes your logon identity the owner, while it does create the daemon to launch the client it does not create the icon for manager on the launch bar. On my system this only appears once you launch boinc manager from a terminal window and does not allow you to lock it there. I am trying to find out how to create the init file to make it possible to do that, or modify the existing files if this can be done.

I'm going to try the BOINC version of BOINC tonight (new SSD showed up) rather than the Ubuntu version and see how I like it.
I would imagine it should be able to lock to the launcher if it is started from the search app thingy (LOL I forget its name).

Thinking, that was actually detuned because of a card mismatch - 980 w/15 CU, 1070 w/16 CU.
Running with unroll 15 for the 980, the 1070 was only at 94% capacity.

. . Using 'nvidia-smi -l' to display GPU usage on my 1060-6GB cards I see highly varying GPU usage using unroll of 10 which suits both cards which have CU=10. It varies between 75% and 100%, so I am not sure that 94% is actually a problem, but then I am running on a Noah epoch PC :)

. . On that subject I am looking forward to saving my pennies and updating to Ryzen-1700 when the dust has settled.

. . I don't think I ever knew its name, but I hadn't thought of that, I wonder if that will make a difference? Hang five ...

. . OK, it took a while but I launched it from that thingy and you are 100% correct. I could then lock it to the launch bar, problem solved. Well done. Thanks.

-unroll autotune helps systems with heterogenous GPUs.

... and the high ar tasks take about 33 seconds on 1080Ti.

33 sec? Let me know next week what the Titan XP does :)

Yes I know the autotune thing, but was using zi3k+ which doesn't have it. I just installed your x41p_zi3t1f with autotune.

Question are you running with or without -bs ? (sorry, laughing moment) You didn't mention -bs in the command line when you posted the app.

No bs :)
I have 12 cores on CPU and use only 6 of them for CPU tasks. -bs can help systems with less cores or systems with heat issues.
The option -bs has its name carefully thought. It is a counter strike to name SoG.

Hi,
for anyone running my cuda app there is a new version to try. Especially if you are experiencing problems with BLC or Arecibo low ar WUs. A big thank you to Gianfranco for testing.

Please backup your current working system and test off line first.

The executable is version zi3t2b and it can be run on sm_35, 50, 52, and 61. (750,780,980,1080 and likes).
With 1 Mb of GPU ram you need -unroll 1. Other can use -unroll autotune.
Use -bs to reduce CPU usage.
Set -pfb to 8, 16 or 32.

You can get your copy of zi3t2b executable here and the source code is here

Please PM any success or failure.

Petri

. . Does that mean I should look into -bs for my rig with the 2 core Pentium CPU? FWIIW, it is running on defaults at the moment and is using between 65% and 80% of CPU (mainly around 70/75). Which is fine because there is nothing else for it to do :) And the CPU temps vary between 32 and 38, so no heat problem.

Only testing can tell. Set the -bs flag and watch what happens to run times.

. . OK, where do I set that? I have not looked into settings other than defaults. I have looked at app_info.xml and found the line ...

<cmdline> -bs -unroll 10 </cmdline>

. . So I take it that it is already set. Do you want me to take it out and see what difference it makes? Or just leave well enough alone :)

I'm sure a lot of people would like to know if and how it effects the performance.
