Retiring Gracefully?

I've got four machines running BOINC now but as soon as I get a new i7 machine finished I'd like to retire the two oldest machines since they do so few units. Is there a way to get the client to retire gracefully -- finish all the work that is in the queue but to download nothing new? I figure that it will be neater that way than simply dropping everything in the middle.

Re: Retiring Gracefully?

If you go to advanced view on those machines, then you will want to go in projects tab and tell World Community Grid to "no new work". This will basically let your computers run what they have on them and then when all is done return them leaving the machines idle.

Re: Retiring Gracefully?

Yes. Go to the projects tab, highlight WCG and then click on No New Tasks. When the queued tasks are completed, upload them and shut down the machine.

Cheers and good luck with the new i7.

Re: Retiring Gracefully?

I can't believe I missed that even though I never saw anything interesting under that tab and never go there. Thanks.

Re: Retiring Gracefully?

I have just started with an I7-920, Win 7 Home Premium 64bit, and I am having a bit of a time with it, requiring too much help from CA's. But, I don't have the technical knowledge many have.

When I installed at first, 6.10.18, I got a shower of WU's from about a dozen projects I loaded in a short order, as fast as I could attach to them. Then nothing. To shorten the story, I backed away to 6.6.38, a wee bit older and maybe more tested in time, but finally to the 32bit app 5.8.16 from 2007. 64bit machines are running lots of 32bit apps, so, why not.

But, still things were not great. I again at first got a lot of WU's which then petered out.

I am asking for a lot of help and getting it from the excellent CA's. Sekerob suggested I start fresh and start slowly with only adding projects slowly in their order of importance to me. He also said to cut the Connect about.. in local prefs from the default 0.30 days (roughly 8 hours) to 0.01. While that is about 14 minutes, the idea is to keep a buffer or cache of stuff ready to go. I had already had that idea and cut to 0.10, roughly 2.5 hours, because I saw that my WU's were rarely even three hours, except Rice at WCG which is around 6 hours.

So, right now I am back to 6.10.18 and following Sekerob's advice about only slowly adding projects. I mean, I have my list of projects, none is more important than any other. I just want to be running eight WU's at one time. I am not in it for points or credits. I am in it for the science that these great institutions pursue.

What I am in my very non-technical way concluding, and with all due respect to those folks who know way more than I, what I am concluding is that the home machinery available now is simply outstripping the abilities of the software. I mean, 0.01?

I have two Vista machines running pretty much on default configurations, on all of the same projects. One in on 6.2.28, the other is on 6.6.36. I think that 6.2.28 is the current build from WCG. The machine with 6.6.36 now has a bright red message telling me to get 6.10.18. These two machines are happily crunching along. I also have a netbook with the Atom N270 CPU, hyperthreaded - that is too big a word for this peanut, maybe multithreaded, nothing hyper about this machine. It is here really just to manage a 1Tb ext HDD full of music and video and for travel. But,
hey, it can crunch a bit on just a few projects with short to medium WU's.

I do not mean to confuse you. It is obvious that I am confused enough for both of us - for a lot of us.

Good luck with your I7 machine, maybe you can come back and teach me something.

jmcgaw, there is something else interesting under that tab, it is the "Update" button that you will have to use to get the last jobs reported to the host. Normally jobs are reported when the client asks for more work, so you see what I mean.... smile

Cheers. Jean.

Re: Retiring Gracefully?

mitrichr, with respect to using an Intel Atom CPU.
Most WCG projects prefer better CPUs to run efficiently and some WCG projects may not finish in time if you run them on an Atom.

However, and after testing, I can recommend adding Atom CPUs to the Nutritious Rice for the World project. Despite its limited instruction set, it seems to handle these tasks very well, compared to other tasks,

HFCC 26 to 27h (too long for comfort, especially on a laptop)
HPFP2 24h (too long for comfort, especially on a laptop)
HCMD 6h+ (may not complete fast enough for project requirements)
NRftW 6.30h ( smile no problems)

Re: Retiring Gracefully?

Time must be running faster in England... RICE always runs fixed 7 hours CPU time. smile

NRW and HCMD2 are by definition resource lightest, latter THE lightest in memory needs but seems to cause a slightly higher processor temperature on me different comps.

Re: Retiring Gracefully?

Ahh, things are starting to add up under my hat.

When playing with this new Atom330 system, I thought I was going to finish several WUs in 6h 30min because I upped the CPU speed from 1.6 to 1.8GHz during runtime, using Gigabyte Easy Tune6. The Bois was no fun at all. Of course when I checked these were HCMD tasks! The NRW finished in 7h and a couple of minutes.

For a while I thought my other Atom was doing more work than an E2160, Intel Core Duo @1.8GHz. But, it is doing about 33% less - going by points.
That Atom330 is on an Asus board, has an Ion, HT is left on, it runs @2GHz, and uses W7 64bit. The native E2160 uses XP 32bit.

Re: Retiring Gracefully?

skgiven -

Thanks for the heads up.

Yes, I know to keep to projects with short WU's, like Spinhenge, Rice, etc.

I check results constantly on this machine. As long as I am circumspect on what I give it to do, I get success results.
