Ok, whats the trick for getting a second WU? I'm running boinc 6.4.5 under ubuntu 8.10 x64 with the 180.06 video driver. The only way I've found to get another wu is to detach/reattach. Anyone else having this problem?
3) Message boards : Number crunching : Is it now time for grid Credit reevaluation on the Grid? (Message 1099)
Posted 5817 days ago by Mitchell
Greetings all,

Just throwing this out there for discussion. I now crunch other boinc 64 bit projects out there, ABC and Riesel Sieve in particular that offer up around 6k per day of credits on a quad Intel Q6600 processor. I, like others get less that 4k per grid WU on this project. It used to be that this project returned alot more credit before in comparison to other projects before these new 64 bit apps showed up and closed, then passed this project.

If this cell type of ps3 processing is that much more performant that pc type processing, shouldn\'t the WU credit be reevaluated to adjust for the changing times?

Open for discussion...

Greetings all,

I consistently have wu\'s that move up to around 90% complete in the span of 3-4 hours, and then take around a total of 25ish to complete the last 10%. This is not to accurate. I know its a guess-timation, but its usually way off. Anyone else noticed this?

I have one running now for 40 hours, seems to use only up to 100% of the CPU according to the top utility, and shows 0.0% in the progress bar. I\'ve considered aborting it, but would hate to lose 40 hours of time.

Greetings,

I\'m getting this above message and unable to retrieve new work to process.

Anyone else also?

I have a ps3 wu running at 45 hours now and its at 86% but shows time running increasing, and time left at over 5 hours and not decreasing. Is this wu dead and should be aborted, or do some wu\'s actually run this long? I\'ve even restarted boinc with the wu\'s still acting the same. I\'d hate to lose all the processing and abort the wu. Any ideas?



write \"top\" in terminal and see the CPU usage of the workunit (it should be around 130%).
WUs should not last longer than 24-26 hours. If you have some other process slowing the processor it will last much longer.

gdf



Here is a typical top output. I\'ve never see the processes go beyond 100% to near 130% are you said, and actually I have 2 ps3 running processes that have exceeded the time aloted to complete and both are running at over 2 days, show 2-7 hours to complete. I guess I wont get any credit for them anyhow will I, so I should abort them. How does grid project treat wu turned in later? no credit awarded even though I\'ve run them for over 2 days ? Can they look at the wu\'s and tell what wrong with them ?

10) Message boards : Multicore CPUs : use more cpu (Message 753)
Posted 5940 days ago by Mitchell
Thanks for the explanation. I was wondering what was going on. I guess its common for ps3grid boinc runs to go for about 30-35 hours then? What kinda of credit return can be expected for such a run?

When I watch ps3 grid procs running, it never goes beyond 10% use, how can I force it to use more? My options in boinc already allow for up to 100% usage, it just doesnt use it.

What you see is only the usage of the main PowerPC CPU. BOINC is not set up to measure the use of the 6 SPE Cells available on the PS3, which are used all by the application and run at maximum. So you could say you are running at 610%, in reality the work done by one PS3 is equal to approximately 16 single core CPU\'s of the same speed. There is no additional use that will speed along the results of the SPE\'s so running the PowerPC CPU at 100% would just be a waste of energy and heat. In simple terms it is kind of like this, think of it as the PowerPC does the disk or memory reading/writing and passes data and instructions to process the data to each of the 6 SPE\'s, it has to wait for one of them to finish, then it gets the result and passes more to that SPE, they need not all finish at the same time. Each SPE can be running different parts of the problem, kind of like attacking it from 6 sides, instead of just starting at the beginning. It operates entirely differently from all other CPU\'s we are use to.
