Topic 198056

Hi everyone,

I just started my "BOINC laptop", to get working on E@H.
The WU's that I've got, are taking ±16 hours to complete.

But I am looking for WU's that take around 4~8 hours to complete.
Which projects, should I check, and which should I turn off in the E@H configuration...?

I have Googled a lot on this subject, but couldn't find anything about it.

Hope to hear something soon, until that I'll run the 16 hours WU's.

Greetings from Holland,
Rik

Hi Rik,

Welcome back to the project. I notice that you first joined over three years ago and that you've added your "BOINC laptop" quite recently. The project really values the support of all volunteers and particularly those who make the effort to keep the association going when new hardware is acquired. Thank you very much for doing this.

I notice that there are Gravity Wave (GW) CPU tasks in your tasks list. With CPU tasks, you only have two choices, the GW search or the Gamma Ray Pulsar search (FGRP4) which uses data from NASA's Fermi Gamma Ray Space Telescope. Whilst FGRP4 tasks might be a little shorter, it wont be by a large amount so there probably wont be any CPU work you could do in the 4-8 hour range with your current host.

Your laptop shows as having a GT 630M (1024MB) GPU which could be used to crunch GPU tasks. It's a fairly low end GPU so it wouldn't be lightning fast but at a guess the crunch time might be more to your liking. Because your machine is a laptop, you need to be concerned about adequate cooling. If you are currently running 4 CPU tasks, that will be creating a certain thermal load which you should monitor. If you were to stop CPU tasks and crunch GPU tasks consecutively, you may well find that you get increased throughput without creating extra heat - just shifting the heat source from the CPU to the GPU. I guess it really depends on how well the manufacturer has allowed for the removal of GPU heat.

If you want to try out the above suggestion you should deselect both GW searches and the FGRP #4 search. The BRP4G search would be the shortest GPU search but there is limited availability of future work so you could quickly run into problems with supply. The BRP6 search is long term and the app has recently been optimised so it would be interesting to see if it would run smoothly and within your desired time frame. If it does it would be the easiest option for you to select.

It's also possible to crunch GPU tasks on your Intel internal GPU. You will have problems if you're not using very specific drivers. If you want to pursue this option you need to thoroughly read this thread. There is a lot of valuable user experience contained there. You should also check out the original announcement for Intel GPUs, as there is user experience in there too. I don't use Intel GPUs so I have no direct knowledge of the problems you might face. If you choose not to use the Intel GPU, you should deselect it in your preferences.

Cheers,
Gary.

One of mine is a laptop with the 610M so yours will be slightly faster especially if you are only running BPR6 GPU tasks X2

Mine has been running 24/7 for almost 3 years.

Even while running Atlas X2 and vLHC X2 it can run BRP GPU X2 in about 20 hours.

Just this month I switched to just running BRP6 X1 just because it is 8-core and I am testing some other projects.......so the single BRP6 takes about 45,000 seconds on average.

Thanks both for the

Thanks both for the replies.
But I am looking for only CPU tasks.

Is that possible within Einstein@Home?
If so, which should I need to tick?

Yes.

Remove the tick from everything else and choose whichever one you want from either Gravity Wave #2, or Gamma Ray Pulsar #4.
