Very short WUs

The last couple of days the WUs were very short, I needed several hundred to get my daily ratio even for my quite diverse machine. They used to be about an hour long, later just half an hour, now it's down to a minute for most of them.

I'm having the same problem now, a couple months after the initial post in this thread. I will get a WU that shows it should take over an hour to run and then it is complete within 10 minutes......not all of the time, but probably 90% of the WUs are doing this. I'm unsure as to whether or not I am getting any credit since my graph hasn't budged from being a dot on the graph.

Hi---I am new to this project and have been wondering about the very short WUs also. Most are "energy exceeded" errors? Am I actually doing any usable work for the project or are these WUs no good? I DO appreciate the credit as another project I won't name will error out up to 12 hours in and give 0 credit. |

I will just say that I have had both very short WUs (like 10 min) and ones that take like 8 hours to do (seems very long).

I keep 2 days cache on my Windows machine and it loaded up with many WU's when there was a lot of short units. Now they are taking hours instead of minutes and I won't be able to finish them before the deadlines. Should we abort overdue WU's?

short work units? Good joke. Hi J. I've noticed that too, some finish in a couple of minutes others take hours i think it's just the luck of the draw, good or otherwise. I had a look at your computer, if you want it to get through the tasks faster you can switch off H/T. I did and it does make a differance trust me. ;) pete. ____________

Why did BOINC just toss the work unit? I must have missed the message because it was earlier, but why did it toss all that work? I could have easily finished that by the 23rd. :@ Also, could this make a difference?

Hi. Yes, on my oldish P4 lappy I have noticed differences in WU lengths, too. But with HT enabled you should still get more work done because two slightly slower WUs are still crunched faster (in parallel) than two WUs in a row with HT disabled. ;-) ____________ Bribe me with Lasagna!! :-) |

Hi. Thanks. That makes sense. Something to experiment with. |

Hi. I agree, Cori. My P4 definitely has a faster total throughput with HT on. But, if the 2 WUs being crunched are memory intensive enough to cause a lot of swapfile activity, then it can actually be quicker with HT off. So it's not a clear cut choice, I'm afraid. Regards Rod |
