Projects of the Month for October 2017 - Page 3

post #21 of 45
Thread Starter 

If the MT apps were native, then we would probably see better utilization.  That is the main reason why I don't really like the vbox apps.  It makes it easy on the project to distribute work to any platform, but the trade-off is decreased efficiency.

 

Is it possible to adjust the vm settings on the vbox tasks? I haven' t looked at the vm config, but it really should be able to max out the CPU if it is properly configured.  I remember reading about how it could be done with the ATLAS tasks for LHC, but that was back when only LHC was distributing vbox tasks.

I can see the instances in Win7 if I open vbox. I have never tried changing the settings though. I opened vbox on a Linux PC and I don't see the instances listed even with a cosmo task running.

My 1950x in Win10 was getting about the same production as my 2p-2670v1s, about 90-93min each, so I am trying out the TR on Ubuntu 17.04. At just 25% complete so far it seems quite a bit faster now.

I'm going for 10yr Zika badge and 100k WUProp hours for Zika. I was pulling in 70 WCG days per day and 2.2k ish WUProp hours a day so it shouldn't take long.

Is there no Lunatics installer for SETI in Linux? The 1st ones I downloaded was cuda60 version. Now 3 SoG which was what I was getting all the time in windows.

Edit: Can't be doing a triple so an edit update. 54-58 min per task now that it's in Linux. Over 33% reduction in run time for ZIKA.

Looks like WCG is having issues. The evening stats update didn't happen and ZIKA is out of work. I'm not getting HSTB either but thats par for the course.

From my end, WCG seems to be working again. I didn't see any HSTB tasks, but I'm not specifically targeting that project, either.

Has anyone tried TBar's installer for Linux?

Can I just copy those files into my existing SETI Project folder? I checked someone else running a 1070 in Linux and I'm getting like half the production.

The threads on the SETI forum are such a PIA since they are so long. They just keep pilling onto the same thread thats several years old with several updates past the original version.

Thread Starter 

I could give it a go, but looking through more than 80 of my tasks, my 1070's performance in Linux was as good or better than any of my wingmen.  There were only a few tasks where my 1070 was a bit slower than my wingman's GPU and that was against a few 980ti's and a 1080.

 

It is difficult to judge performance with the wide variability in task run-times.  Once I have a few more days of SETI on my 1070, I will have something to compare the optimized app to.

A averaged 100 tasks of my own and the #4 computer which has 4x 1070s in Linux. Points per second was over mine at over 60k RAC a day per GPU. .24 vs .48 point/sec. I was getting maybe 30k in Windows before I moved it to a Ubuntu machine. I think I copied whole SETI project folder over to the Ubuntu computer.

Looking at the top host there is quite a range of RAC per GPU. 4x 1080 Ti behind 2x 1080 computer.

Looks like some of the radio telescopes used for SETI were damaged from Hurricane Maria. I guess I never knew it was in PR

I asked over at E@H if they are still getting data from them.

Oh snap a triple... a SETI Linux update. I dropped in the couple of files, downloaded the CUDA files from the google drive and of the couple tasks that have validated there is a definite increase in production. Pretty simple.

From ~0.24 points/sec to over 0.5 points/sec. Over double! There are other tweaks as well with the command line options but I'll try this for now.
