Hi all

If anyone fancies staying up past 11pm tonight, then feel free to check here or on the Formula BOINC website to see which is the chosen Sprint.

I would quite fancy a GPU + CPU based project....

regards
Tim

Sprint on project Collatz Conjecture
from 06/29/2017 22:00 (UTC) to 07/02/2017 21:59 (UTC)


So no swapping around needed here, just a network disconnection :)

HI Mark

I'd already finished a cache of Moo tasks and have now downloaded a swodge of Collatz. :-)

Hopefully we can do well on this ;-)

Hi Tim,

I was in the middle of adding a few points to Collatz to catch Boinc Synergy in the main table so was all set up anyway.

Unfortunately, one host had been off the network since the morning with a damaged cable and when I replaced it last night, it uploaded almost ten million points of accrued Collatz credits. If I'd waited another fifteen minutes to find out what the sprint was I could have held off uploading them until tonight :(

However, all GPU equipped hosts are now off the internet and crunching away :)

Currently fifth by daily RAC in Collatz and only Gridcoin and the Czechs above us are in our league. I think both Chris and I are pretty much maxed out though whereas other teams may have a bit more room for improvement. Still, USA are back in 36th place by daily RAC so that's encouraging :)

Regards,

Mark

HI Mark

Shame about the faulty cable...10 mill of credits would have been useful...oh well, done now so no point "crying over spilt milk".

I had an issue with my 32-core...I added Collatz as a project but forgot to install the Visual C++ 2012 Redistributable...so, a few tasks errored out within seconds. Was too tired last night to sort it out but I was able to suspend the project so the cache was protected.

Have now installed the vc_redist.x64 and the Collatz tasks are now being crunched. So, I'll have quite a few tasks to upload tonight so that will help. :-)

If a few other members can get onboard and crunch some Collatz then we might stand a good chance of getting in the points by Sunday ;-)

regards
Tim

Hi

As this is a new computer just wondering what the GPU temperature should be. Just restarted Collatz and it's currently running at 77 degrees, fan speed at 72%. Seems a bit warm. Is this about right? Info from GPU-Z https://www.techpowerup.com/download/techpowerup-gpu-z/

Hi Tim,

My own fault, I should have thought but I was in too much of a rush to get everything ready and running before the sprint was announced.

I've done that as well when adding new GPUs/hosts :) I think Collatz are used to a few hundred trashed WUs a day :D

Same here, all set for 11:05 PM.

Fingers crossed. We should do reasonably well in it anyway but the more the merrier.

Hi Mike,

My closest equivalent host has two GPUs in it and is showing GPU temperatures of 82 and 85 degrees with fan speeds of 76% and 83% respectively so I don't think yours are too far off.

A lot depend on the air temperature inside the case, no matter how good the heatsinks are or how fast the fans spin you're never going to get below the surrounding air temperature. Since my GPUs are adjacent to each other, they'll be pushing pre-warmed air through their heatsinks.

I wouldn't worry too much unless the fans get into the 90% usage figures, they're obviously coping with whatever load they have or they would be flat out.

Maybe you could try the oil cooled method that Chris has found http://www.ukboincteam.org.uk/newforum/viewtopic.php?f=18&p=114213#p114210 ... although I wouldn't recommend Castrol GTX!

Regards,

Mark

Hi all

I would suggest you try MSI Afterburner...it's designed for OVERclocking GPU's but I find it really useful for UNDERclocking, which keeps the GPU temps down, plus you have more control over GPU fan speed.

https://www.msi.com/page/afterburner

For the pair of GTX970's I have them set at a Power limit of 85% and a Max Temperature of 75 deg C. Current fan speed is just 75% (of max speed).

Tim

Hi

Thanks guys, Might try the afterburner sometime - I don't like running the GPU flat out too much.

Just to add to the discussion (now I have just read the previous posts).

If you try the oil method, video tape it - I could do with a laugh :)

My GPUs have run at around 70-88c pretty much continuously for the last 12+ months; you will know when they are *too hot as the fans will get to 100%; I have yet to see this.

I found a good way to bring down GPUs temps is rather than push air into the GPUs, instead put a fan behind and pull the hot air out, that seems to work quite well, especially if you also have it pull hot air from the back plate too (if you have one on your GPUs).

I have now started Collatz power crunching on all 6 GPUs; thought I would start early just to make sure everything is okay.
Chris Cambridge is my old account; I am currently crunching through a private new account.

HI all

I'm guessing but I think the midnight stats might show a bit of a deluge of Collatz credits ;-)

I wonder why ???? hehehehehe

Hi all,

Network back on and abusing my unlimited upload capability :D

I hope the Collatz validator works better than the LHC one, it's going to be under a bit of stress at the moment.

And your contribution has been noted by Collatz making you their user of the day :D

Well done.

Hi all

OK, so one of my 2 GTX970's isn't crunching on Collatz, though it was working fine on Moo.

I've looked on the Collatz Message boards and a few people have had similar issues, but no solutions.

I've throttled back the number of CPU's so that there are 2 "left over" for the GPU - my PC requires 0.914 of a CPU per GPU task.

Here's the relevant event log section:

30/06/2017 00:41:18 | | CUDA: NVIDIA GPU 0: GeForce GTX 970 (driver version 368.81, CUDA version 8.0, compute capability 5.2, 4096MB, 4009MB available, 4170 GFLOPS peak)
30/06/2017 00:41:18 | | CUDA: NVIDIA GPU 1: GeForce GTX 970 (driver version 368.81, CUDA version 8.0, compute capability 5.2, 4096MB, 4009MB available, 4423 GFLOPS peak)
30/06/2017 00:41:18 | | OpenCL: NVIDIA GPU 0: GeForce GTX 970 (driver version 368.81, device version OpenCL 1.2 CUDA, 4096MB, 4009MB available, 4170 GFLOPS peak)
30/06/2017 00:41:18 | | OpenCL: NVIDIA GPU 1: GeForce GTX 970 (driver version 368.81, device version OpenCL 1.2 CUDA, 4096MB, 4009MB available, 4423 GFLOPS peak)


I've also added both a cc_config and an app_config XML file, to no avail :-(

<cc_config>

<log_flags>
<http_debug>1</http_debug>
<http_xfer_debug>1</http_xfer_debug>
</log_flags>

<options>
<use_all_gpus>1</use_all_gpus>
<report_results_immediately>1</report_results_immediately>
</options>
</cc_config>



<app_config>
<app>
<name>collatz_sieve</name>
<max_concurrent>2</max_concurrent>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
</gpu_versions>
</app>
</app_config>



Anyone give me a clue what I'm doing wrong ?? (It's late so my brain might not be in gear) !!

regards
Tim
