Hey all,

I know from looking to much that one of my GPU's takes about 30 mins to complete a work unit and about 60 mins for one of my 4 cores to complete a work unit!

Ive come to look this evening and its reporting like nearly 6 hours for a GPU WU and the same for a CPU WU.

Ive also noticed that the seconds instead of counting like 9 8 7 6 5 4..... its going from say 5:50 remaing then to 5:21 in the sapce of one second, how have the times become so far out of sync??

D
Cheers

Very Low Angle Range (VLAR) work unit?

Fall back to CPU?

Perhaps it's time for a reboot.

Gruß,

Dan, relax. That is just boinc doing its scheduling thing. Leave it to its own slightly warped devices & it will all come right :)

It may look a bit of a mess but it will prioritise as it sees fit. It will start a few then panic as it downloads more pressing tasks & then switch to them. Trust it, it will all come out in the wash.

Boinc doesn't really understand the concept of 2 different applications running on the same project on the same machine. When you have 2 apps running with such different execution times on the same data with the GPU much faster than the CPU, it overestimates the time a GPU unit will take to run. As the GPU unit progresses BOINC makes a better & better estimate of remaining execution time resulting in the "To completion" time stepping down by several (or many) seconds at a time. 20 or 30 seconds at a go is quite normal.

Don't be fooled by the CUDA units being call 6.08 and the CPU ones 6.03: they are really the same units just branded differently. I've never been sure why this is done, really they could be called anything, it just seems to be a housekeeping nicety.

I advise you to put your feet up & eat some more of those nice Cumberland bangers from your profile :) BOINC will look after itself.

Ok, it's possible you got a VLAR on one of your GPUs. Since they take so long to run on a GPU they've got your completion time all out of whack. The dropping 10 or 15 seconds a second is the running WU correcting it's estimated time. The waiting to run and high priority are also caused by this. Since the completion estimates jumped up so high it thinks you wont be able to finish those shorties within deadline so it is getting them out of the way. Oh, and I only count 6 slots open. those waiting to run are suspended.


PS, I wish you silly Englishmen would learn how to write a date correctly. When I first looked I thought you had WU due in August.! :-)

So my PC hasn't gone mad then thats a relief! Will the slot folders remove themselves too when they are no longer needed as there are currently 9 of them in my data directory, im a bugger for wanting to keep my files tidy, unlike my desk and work area lol!

Those bangers were excellent, cooked on that barbi in the peak district on a climbing weekend with the guys! Good times, and more to come as soon as it warms up, if anybody wants to join us?

There is nothing quite like a good banger barbied in the wilds - ahhh.....

And to perryjay: I resent being called "English". I am Welsh & proud of it :} You may call me British but please not English! Don't get me started on the totally illogical, messed-up way you Americans write dates!

Ok, who am I talking to? I was teasing Dan about the screenshot he posted. Took me a minute to figure out he was from GB and his days and months are backward. It's almost as bad as all those useless Us you guys stick into every other word! :-)

Everybody knows you should be using the ISO 8601 date format YYYY-MM-DD :p

Its a great way to start file names if you want an easy way to sort them into a date order - I do actually use it :}

Both the ISO & British date orders make sense to me but I have never seen sense in the mixed up US date order. But if using it makes you happy ........

I never knew YYYY-MM-DD was a standard format. I've used it for years for things like my IRC log names & such. I was using the standard US format MM-DD-YYYY before that. As it puts the month & day in order, but then you loose all order once you get into multi years. I'm just glad that the format for time is the same for everyone. Well maybe not the format with 12 & 24 times, but at least the placement of the values is the same.

The nice thing about standards is that there are so many to choose from.
