I'm new - just started Thursday Feb. 26, and everything was moving right along. Then this morning I added World Community Grid to the projects (I'd thought I'd already had them, but no...just Milky Way). So now WCG is running, but there are four MilkyWay tasks on permanent "ready to start" status but they're not starting - just sitting there.

BOINC is confusing to me - even how I got MilkyWay in the first place is confusing, since I thought I was signing up for WCG, and both use BOINC. I set my preferences to give 100GB of HD to BOINC, and I let it run 16 hours a day. But now MilkyWay seems to have put itself on hold and only WCG's Conquer Cancer is running (and much slower than MilkyWay was - in the last 24 hours I'd completed at least a couple dozen MW tasks, none of which show up on my stats).

Any suggestions (besides flaming me for ignorance - I admit it, but I'm trying with the limited amount of time I have to get this thing up and running). I find the enormous list of FAQs and threads on both MilkyWay and WCG far too big and arcane to spend much time trying to dig out what may help and what is irrelevant, and tech-speak kind of goes right over my head. I'm not a techie, I'm a poet (sigh!), but my heart's in the right place and I'm trying to do what I can within my limited technoability. Thanks.

Not quite sure what's going on there... but you could always try detaching from milkyway and re-attaching. When all else fails restart, lol :D

It's odd that you signed up for MilkyWay meaning to...

"Not quite sure what's going on here..."

You too? Argh! Great cartoon, though. I downloaded BOINC, and the WCG popped up and I selected the default list of six projects. But then a separate window with Milky Way also opened, and I'm totally galaxy-oriented (loved Benford's Galactic Center series), my wife just assumes I'm out there somewhere most of the time...anyway, I signed onto Milky Way also assuming it was all part of the same thing as WCG.

Milky Way has finally started running, albeit much slower than it was, probably because I'm also trying to cure cancer at the same time as exploring the galaxy, and really, you need time travel to do all that efficiently. I wonder if my computer would be best used by concentrating just on one task, or using smaller amounts of space on each of several tasks - a cost-benefit analysis is needed, but I'm as capable of that as I am of figuring out "what's going on here."

Thanks for the response and the laugh.

Thanks. That's very interesting - much more detailed than what I get on the home site clicking on my account. I bookmarked it. And Milky Way is finally running again, though very slowly compared to yesterday (pre-WCG tasks).

Which is more important in how much of these calculations the computer can handle at one time: disk space or memory?

I increased the amount of work in the workunits today by about a factor of two. So they should take around twice as long to complete, but will award twice the credit.

CPU or GPU speed ...

So the answer is neither of the things you asked ...

THe disk space is only used to hold the applications and data. And most of the time the amount of space, even for large numbers of projects is minimal.

Tasks vary depending on the project and the specific task. On my systems, Milky Way tasks take from 9 seconds to 30 some minutes depending on where they are run. On WCG, from a couple hours to more than a day (30 hours or more).

As Travis said, he changed the size of the tasks issued so that they take longer so if they used to take 5 minutes, it is likely that they now take 10 (pulling numbers out of my ear).

One more example, I have one task running that is projected to take another 1326 hours after running for 515 already ... (CPDN).

The way to learn is to play, ask questions, and play some more.

if the progress bars are increasing, you are doing the work and things are likely fine.

One more thing, you are running a Power PC type Mac and sadly these are slower on almost all projects. I cannot recall if that is for a G4 or G5, but, I shut down my dual G5 2.0 GHz because is so slow ... :)

That does NOT mean that you should be here, or should not contribute ... it is just be warned that your machine will not run tasks as fast as other machines.

There are a couple projects that MAY be able to run tasks faster per unit time (optimized for the Power Mac architecture) but, they may also not be of interest to you ... :)

Oh for goodness sakes, I may not have an Mac, but I just can't take the suspense - please tell! :P

(PS I'm impressed with your 1326 hours CPDN - I have a 473 hour due to finish today, a real short one ;)

WEP-M+2 and Einstein come to mind. At one time EaH ran much better on the G5 than just about any other system because of the hand coding of the Altevec vector unit. And if I recall correctly WEP is also faster. I do know it runs a lot better on my slow Linux system than my Mac Pro with much faster Intel Xeons, and my recollection the same was true of my G5.

It is a "Coupled" model and it is a slow machine. It is all the way down to 1320 hours to go now ...25.245% done ... after I got that one I turned off Coupled and now mostly get slabs ...

I think my first BBC Climate model, with a slower machine at the time, took well over 6 months to complete. Or was it 6 years? It certainly seemed like it at the time. Right now a bit quicker on a faster machine, CPU time 471:21:32, 00:58:17 to complete. Slightely different to "CPU time 00:00:03" here ;)

Back in that day I could not get them to run well enough to get anywhere ... so I stuck with SaH Classic which in that day took 33-40 hours to complete one task. Now I think there is 16-32 times more work done and the time can be down in a few hours time ... or on a CUDA, several minutes...

You can now crunch climate on CUDA?

SaH ... I could not get climate to run back then ... hence SaH, now SaH can be run in moments instead of hours to days ...

Sorry, I didn't read it right. I thought you were talking about climate, raced over to the climate forums and decided they were hiding it from me

[edit] Sure SaH can do it in moments, but I expect they still don't hear the aliens...

CPDN I don't expect to ever see in CUDA or any other GPU anytime soon as the basic model code is FORTRAN and is not owned by the project (unless that has changed in the last year or so).

Completing a CPDN model remains an achievement. At least I think so. I finished one yesterday and have another finishing today - it's like a smile after a long slog. If they do something with it so that they complete in a blink of an eye - it just won't be the same ;)

Yeah, I just completed a couple my self ... on one system I already had another lined up so I took it over suspend. The other system I have to wait till it will go get one ...

I do what I call 'PC hopping'. I occaisionally have access to a PC, say for a couple of weeks, eg if I'm on a course, and start a CPDN task on it. I then copy it off and continue it on another PC, and even another, and another perhaps. I use a technique whereby I don't install BOINC on the machines because of the temporary nature - just copy down the BOINC folder and run.

I have a few CPDN models queued waiting to finish. The one big danger is getting confused with which is the latest copy and crunching the same model again, and again ;)
