Are we seeing the effects of Monster Work Units?

The work unit count is down today which usually means a batch of "Monsters" are filtering through. Anyone seeing any with run times greater than 10 hours ?

If a long running batch arrive the whole grid rocks back while it digests them knocking run time on the head as we await the results. When they do arrive we have a bounceback effect as all those long run times add up to a Monster Daily Score.

We haven't seen this for a while due to our increasing numbers this effect is smoothed by the number of machines involved and also the number of projects - a monster batch will usually just affect one project at a time.

I haven't seen any myself but that doesn't mean they are not out there.

Anyone suffering the trials of a Monster Work Unit? In the early days run times of 300 hours were not unheard of shock

Re: Are we seeing the effects of Monster Work Units?

I've not seen or heard of monster WU's but it may be HPF2 with it's different quorum. I don't think it's three given that 19 copies go out but I don't think it's 19 either. I think Sek has posted a link to that topic. I just haven't had a chance to get to that yet.

Also, if BOINCers are upgrading to the 5.8.x levels, they may well have machines sitting dead in the water despite the fact that BOINC is reporting that the current WU is Running. That could contribute some depending on how quickly folks upgraded.

Re: Are we seeing the effects of Monster Work Units?

You guys were quick, but i was quicker... lol .... the Sunday numbers were tell tale already and it's not BOINC. Yes the HDC's were loong already, the FAAH's are taking 8+ on my C2D and the HPF2's are well into the 6th hour too... that should translate to some Tuesday booming drooling

The HPF2 beta was validation from the 15th and a set of 25, but now in production that was scaled back to from the 11th and 19 in a set.

Buona Notte.

You can't beat a good Tuesday Sek peace

Keith I'm running 5.8.8 and from my point of view things haven't changed (my queues still empty down to the last work unit). I haven't seen any dead in the water WU's thoughthinking

Re: Are we seeing the effects of Monster Work Units?

Aloha David...
I crunch w Team Andrax, and there is Jonathon Murphy, and Dick Dastardly that produce roughly 100 times my daily bread. I figure my daily average to be about 400-500 points, regardless of what agent I am currently crunching. Amazing, but I am really proud to be with them. I believe we have less than 20 active members, yet the mix of ordinary, yet sleek and fast home pc's like mine, and the monster crunch nets of theirs, makes for amazing returns. Paraphrasing Johnny Cool, our small, potent team represents WCG in the best possible way, with all helping to the common good...
good luck rose cool

Re: Are we seeing the effects of Monster Work Units?

My longest WU's are just under 10 hrs for faah. My work queues are up to 6 waiting with my connect to internet set at 2. I am resisting setting it to 2.5 cause things are soooo smooth right now don't wanna rock the boat...the schedualler is doing such a great job smile I'm running 5.8.8 as well and happily reporting not a single error or anything!

Re: Are we seeing the effects of Monster Work Units?

Well, there's the problem in 5.8.8 where it made your DCF value go up when it should go down. That's not good for keeping a small queue of work on hand. So I tried 5.8.9. I found that it would fill my queue to what I first set. If I increased that, I would get more work. But keeping it that way was proving to be another matter. Everything seemed to get ignored until you were down to your last WU at a point where it was closing in on finishing. That computational deadline that a WU has seems to cause royal havoc if you ever cross it and it seems like if you have any WU for more that 48 hours, you'll cross it no matter your settings. Cross it and you get nothing until that WU is basically done. What seemed especially frustrating was that if you ever suspended a project, WU or maybe even hit the update button, the scheduler seems to go schizo on you. I literally had 5.8.9 BOINC Manager telling me that I had TWO WUs in Running status - this on a 1.5 Ghz Pentium M!! I've seen it skip over Waiting to Run (the old Preempted status) to start a Ready to Start WU that had a LATER report deadline. If you're going to run 5.8, don't keep a big queue and don't ever click on any of the buttons. That's the best conclusions I can make at this point and I hate them. I conceptually understand (at least I think I do) where they are trying to go with BOINC. Trying to prevent WU's from missing their report deadline is a good thing. Not letting you get more work than you can complete before the report deadline is a good thing. However, they have to have made some pretty major changes that probably work just fine if you never deviate from the "ideal path". Take one step off and, so I suspect, you get into some serious logic conflicts. The intended direction is good; the goals are good; the early growing pains can drive you crazy.

What's that coming over the hill is it a Monster?

Now I'm confussed biggrin

Are there Monsters out there?

(Monster defn - A work unit running more than about a days worth)

Is there a problem with BOINC that didn't exist before causing work not being done?

Dave

Re: What's that coming over the hill is it a Monster?

We've seen a couple of reports of HDC using above-average amounts of memory.

FAAH is running normally here. Not running HDC at the moment.
