I already know that different WUs have different sizes -- thus, larger ones take longer to finish. But my highly scientific observations (i.e. my rough estimation of the speed of those squiggly little line graphs) seem to indicate that my computer is actually crunching them at different speeds, as well. I've checked to make sure WCG is running at "full speed" (100% CPU) each time, with as few tasks running as possible, yet still there seems to be variation in the speed of the graph/molecule rendering.
----------------------------------------Is there some factor that affects how fast the thing runs? (Such as the size of the molecule it's testing from WU to WU?) Or maybe I'm wrong and the aforementioned rendering speed is completely independent of crunching speed? I'm only concerned because if there is no coorelation, I need to find out exactly what might be slowing WCG down. If someone's already answered this, by all means, feel free to just post a link to the thread. Thanks, everyone! .:MithrandirMage:.

Well, from my small amount of knowledge from proteins, the bigger they are, the more variations on folding the proteins, therefore, the correlation of big proteins to slow graph movement, and vice versa... that is what I can infer...

This is the sort of question that can only be answered by somebody that has looked at the program, but I would imagine that each part of the string folding up is affected most by nearby components. So, depending on the shape, there are a lot of force vectors being computed or only a few. [Assuming that the effects of distant components are negligible, at least while we are folding in low resolution.] Then there is the length of the protein. But I expect that the reason the crunching time is non-deterministic is due to the different shapes that it might assume while folding.

Thanks, guys. I see now that it's a rather technical question. I suppose I can't ever be sure whether or not I'm truly performing at 100%. Regardless, I shall continue giving my (however small) contribution to the common good.
Thanks again! .:MithrandirMage:. |

Yes, for more difficult proteins to fold, the internal processing loops can run longer sometimes and thus make the statistics graph update less often.

Many thanks. It eases my mind to know that I (or rather, my computer) am doing my best to help the world.
Thanks again. .:MithrandirMage:. |

It could possibly be some other program or programs needing the processor. I know they say wcg is active only when the cpu is not being used and that may be so but some programs use the computer when it is turned on, for instance I run seti and it is always an active program. WCG runs much slower when I have seti running. I take seti offline and wcg speeds up. It seems to process even when I am reading my email, and I didn't think that was suppose to happen. I hope this helps.

The World Community Grid Agent is set to run at lowest priority. I am surprised to hear that Seti@home ever allows it to use anything. However, even though it does not interfere with any other program due to its priority, it can still cause slowdowns because it takes up memory and competes for cache.
If this is a problem, then instead of running it in the background, the Agent can be set to 'Run Only As A Screensaver' by clicking on the check-mark at the bottom of the Agent to show the Preferences page and then by checking the option in 'Device Options' and clicking Apply. Warning: To run in screensaver-only mode, it is necessary to actually use the World Community Grid screensaver. If you do not use the screensaver-only mode, then you can run any screensaver, or none at all. Secondary point: Any screensaver slows down the crunching speed of the WCG application program Rosetta. The best choice for a screensaver is blank. This is always better to choose than none. Monitors keep changing and for a generation there have always been some new technologies that burn-in unless a screensaver is used. Currently, many of the plasma-screens need screensavers. If, like me, you are irritated if the screen suddenly blinks into screensaver mode while reading at the desk, then set a long delay rather than setting none for screensaver in Settings - Control Panel - Display. |
