As was noted, the extension was *not* applied to HFCC work units [not possible in fact]. There is though variability in the time it takes for different compounds to complete all the dockings, there's always been throughout the project. The average run time is though very constant, as can be seen in this chart: http://bit.ly/WCGHFC [light blue line near bottom]. I agree. I think these large jobs are few enough so they do not change the average length of run time over 50,000 to 60,000 WU per day. They would only have a local DCG effect on an individual machine for a short time. It self corrects pretty quickly. Thanks. Cheers

HFCC_ target-9_ 02545924_ target-9_ 0001_ 0-- claimed/granted 110.9/ Run time 107.55 9/11/2012 10:56:01 AM Definitely the longest unit I think I have done. It will be interesting to see what the wingman shows. Cheers

Either they have a real slow computer or your computer is on steroids. Thats a pretty big difference.

It would be my computer which is slow,slow,slow. It is an old HP GL360 which benchmarks at at 850 I think, about the same as a low end P4. Mine is the one which took over 100 hours to finish the task.

Has anyone noticed large runtime differences between workunits?
----------------------------------------I am seeing work units finish with runtimes between 4 hrs and 18 hrs. I don't remember seeing this behavior until the project was slowed down.

I don't remember seeing this behavior until the project was slowed down. I have crunched a little over 10,000 units in this project and as far as I can tell this project has the greatest variability in run time of all the projects. Even on the same machine there is a high degree of variability in length. I would not worry about it. Some molecules are just more complex than others. Cheers

Yup, the harder compounds have been showing last few days... off and on. There's no predicting at all when it happens.
----------------------------------------edit: The nature of "non-deterministic" target calculations. It's like a puzzle, but each puzzle is different and has a different unknown number of pieces... how much energy does it take to slot the compound molecule into a docking position... how snugly does it fit in at lowest effort [energy] and would it then block that key position form then accepting the sick making element to enter the cell? edit2: But, as was noted early in this thread, there never was an extension / run time increase of 20% through size-up. The techs stick the maximum dockings in a task [256], that's all they've been doing since early on in the project. [Edit 1 times, last edit by Former Member at Jan 11, 2013 8:51:15 AM] |

Here is a chart of the last 365 days of HFCC showing the average amount of time per work unit. It is trending up a little bit lately, but as can be seen the work units do vary from less than 6 to more than 8 hours. This means there are probably some jobs in there which are considerably longer than 8 hours. Not as good as Sekerob's charts but I thought I would give one a try.
---------------------------------------- Cheers Edit: Fixed the two days with bad data and fixed the size so it fits the page.
