LHC@home

Greetings,

Every time LHC (SixTrack) has WUs I get a bunch. Every time I get LHC WUs they run in high priority mode. Other projects I run do not get a chance to run until LHC runs out of WUs to send and I finish my cache of LHC WUs.

My main project is SETI. I have 4 other projects I use as backup, LHC being one that I do not use primarily as a backup project. The other 3 are set to get no new tasks. I have my resource share set high for SETI and lower for all other projects.

Is there some other setting I can change that will allow SETI and LHC to run concurrently? I have 8 SETI WUs, waiting to run, that have not had any CPU time for a few days now because LHC runs in high priority and I keep getting more WUs from LHC. I do not want to set LHC to get no new tasks; I want it to run along with SETI.

Thank you for any consideration given to this problem. :)

Keep on BOINCing...! :)

Hi,
how is your cache settings? I noticed that you have 32 WUs in progress on your host, which is quite a lot. I remember that there used to be limits set by the project how many WUs you can have in progress at one time, but whether the limits are still active I don't know. I haven't been able to grab more than 6 WUs at a time for any of my hosts, but then again I have a minimal cache setting in use 0.1+0.1. My resource share for LHC is about six times higher that Seti, Einstein and CPDN so I would expect to get more WUs for LHC than you do.

Greetings Harri,

My minimum and additional buffers are set to 5 days and 0.5 days respectively. They are set that way because of the server problems that SETI has on occasion. As I mentioned, SETI is my main project. Been with them from the start, before BOINC.

I'm not sure about other projects, but SETI has a daily limit of 100 CPU and 100 GPU WUs. We cannot have more than 200 total in progress WUs in any given day.

My shares are set to 100 for SETI and 0.5 for all other projects. I forgot to mention that I do run FreeHAL also concurrently with SETI. It is a non-CPU intensive project. Right now they are having some problem, server I believe.

If you set your minimum buffer setting to 1 or greater, you will get more WUs per day.

Thanks for responding. :)

Keep on BOINCing...! :)

couple of thoughts ...

I believe it is the high cache setting that causes Boinc to think it has to run LHC tasks as "high priority" mode as it does not think there is enough time to finish. So if this is true turn your cache down to .5 / .01 and see if the status switches to "running". That being said, if you still have too many taks to complete in the time allotted you will remain in "high priority" mode.

As for continually getting tasks even though you have it set to low resource usage, I'm guessing it may be a combination of a large "switch between tasks" time which tells BOINC to exactly that ... not switch of LHC and then every time a high priority gets reported, it pulls more WUs.

Greetings Steve,

That did the trick! I reset the buffer to .5 / .1 and now SETI WUs are again running while the LHCs are waiting. I shall leave it as is and see how things go.

Thanks a lot Steve! :)

Keep on BOINCing...! :)
