WOOHOO!!!
Just passed 10K Seti 10 min ago (or so)
& just passed 20K boinc in the last day!!
22) Message boards : Number crunching : The average granted credits are quite low. (Message 168237)

IMHO it's because of the low benchmarks for P4 HT machines... very low. They crunch WU quite fast, have low benchmarks so the claimed credit for those machines are LOW....


I have a couple of AMD XP's at home & my dad has a P4 with Hyper threading.

Check out the difference in the claimed credit!

23) Message boards : Number crunching : New server status items (Message 166508)

I have just noticed that my status graphs have been showing a blank line for the past few hours.

This was due to the rewording of the in progress, ready to send and waiting for validation status indicators. Whilst investigating why this had broke, I noticed they have added 2 new indicators, waiting for assimilation and waiting for deletion.

My graphs have now been fixed and are starting to collect valid data again and these new indicators have been added to the graphing mechanism.

Thanks for adding the extra data guys. It is always nice to have more of an insight into what is happening.

Cheers

Um, but is it just me, or are the validation graphs unable to tell the difference between 281 results & 281k results?
24) Message boards : Number crunching : Question on this granted credit (Message 165007)

Post:
If it takes at least 3 valid results to be returned to grant credit how come 2 people where granted credit on this one and I was given zero. If there was an error on my returned result how come they granted credit? I have never had an error on returned result and it does not say I had an error, I was just given zero credit?

Thanks


I have had simular happen to me with a E@H WU. I got very little credit, as the WU that failed validation was used in deciding the granted credit.

http://einstein.phys.uwm.edu/workunit.php?wuid=1945766

The top three resutls were the first in. The result passed validation, even though the 3rd result is invalid.
I wonder if there has been a new version of the validator out, and it has a bug in it?


I noticed that both of you are using Windows Millenium Edition. I wonder if that has something to do with it?

I think the file server is impacting both crunched & un-crunched WU's . . . .

it is spending more or less *all* of its time in disk wait.

The bottleneck is the fileserver that contains the workunits/results. For some reason it cannot read/write fast enough. We can add a million validation processes to a million separate machines - won't go any faster.

Maybe you might consider shutting off a couple of splitters then for the time being. . . Maybe by creating less files, there will be less activity on the file servers & they can catch up (Almost an outage, but just restricting the amount of work available)

I have noticed on the server stats that penguin seems to be doing all the validating, deleting, assinilating, and some other stuff as well. I was wondering if it might be an idea to take one of the splitters offline & get them to help on validating.

Making work doesn't seem to be a problem, just dealing with the results is!

Post:
One thing I don't understand is that my results usually claimed credit in the range between 25 and 32 pr WU - but when I started using an optimzed worker it only claims beween 6 and 7 credits pr. WU


The reason is simple. The claimed credits are based on your benchmarks * time (basically). So less time = less credit

Actually, I have noticed on a P4 with hyper-threading, that boinc seems to benchmark it at 1/2 (1/2 for one WU, 1/2 for the other), when in reality 2 WU's finish far quicker at once then if you were to run them one at a time

Now, I was just looking at my results. 2 of them have 0 credits due to this problem. All the download errors were reported before my computer had started work on the WU's. Can SETI not send a stop work order (or something like that) to BOINC to not persue further work on that WU?
