7th BOINC Pentathlon - June 5th-19th 2016 - Page 61

post #601 of 1534
Well I made the mistake of getting GFN15 and GFN16 tasks...they are only 25 points for a minute or less of work. Looks like best points are Sieve, GFN18, GFN20. The GFN20 tasks says average of 14 hours, but on my 980TI is finished in 4 hours plus has a 10% bonus. 32K points...not bad. Afraid to try the GFN21 because may not have enough time to finish.

Keeping 4 cores on CSG...though might be a waste at this point.

My only guess is that they follow a Deadline execution priority which cannot be regulated, it seems.

What I would like to do is run POGS, but as soon as the client gets a CSG task, it would get crunched and reported back immediately.

Could you share your workarounds if you've found any?

My bet would be that the deadline for the CSG tasks is closer than the POGS tasks, therefore the boinc client wants to run CSG over pogs in order to make sure everything completes on time. Although I have experienced quirky behavior like this from time to timr for apparently no reason. Sometimes a different client version will behave slightly differently (I think the newer versions are a little better at this than the older ones).

But also your hardware can be a factor, I see this behavior more on slower machines than on many cored xeons or highly clocked i7's.

Agreed. I am going to focus more on CSG today.

Needless to say, once I already wasted several hours without production because of this.


Edit:
Yes, I stand corrected. redface.gif
However it was still funny.

Thats what I was trying to avoid as well. I figured pogs event would complete before PG so I let them stay nearly completed. Oh well.

Seti-Germany site is up for me.

They seemed to went back online like 5 minutes ago. I really hope they are not being attacked again.

PPS are your best bet. ~3400 points a piece and on your 980 should only take ~8 minutes (depending on how well it's fed. My 290Xs can also do them in 8-9, but my GPUs are running lean @~80% with 5 cores on CSG, so it takes 12.5 min instead avg.).

You'll be getting 2.5-3x as many points in 4 hours as that GFN 20, even with the 10% bonus.

ah crap...ok, well I made changes to my preferences. I'll have to abort the bigger units when I get home from work...
I've been keeping a core free for each GPU, so it should do ok.

EDIT: yeah you're right...I see some past units done.. a little over 6 minutes for PPS or either my 980 or the 980TI

It's no worries, I made the same mistake when I was bunkering PG units and thought I was getting really good points with the 18s.

I wish it'd been made apparent in the first post of the cross country thread that it was by far known best PPD task when we found out it was PG. It's a good lesson for next year though if we come on a project with people who've experienced it and know the best tasks to get.

Yup about 8:35:8:45 on my 970. I was able to play with ProcessLasso and get 6 pog tasks running with PG PPS tasks and still keep the GPU util at 98-99% most of the time. 2 idle CPU threads.

It's because of how the manager operates with version 7.x - at least that's how my previous research into such has shown. While it does go by resource share, if you've had a project loaded for some time but it hasn't been crunching, it will give that one priority. In essence, over long term (24+ hours) it balances out and assigns things to be taken care of based upon resource share while keeping deadlines in minf, but in the short term it behaves in a manner that comes across as wonky.
