I read on one post that the grid agent uses varying amounts of memory based on how much it needs...
Last week I was completing units every 8 hours or so, and using 80 MB, and this week it's taking me 24+ hrs, and I'm only using 25 MB. I assume that the extra time is due to a larger protien, and not just that the agent is using 1/3 of the memory. Is there any way to increase memory availible to or used by the program? |

Two different things here. Rick Alther recently released a version of Rosetta cutting down the size from about 72 MB to about 25 MB, plus the new version requests 200 MB of virtual memory rathher than 300 MB. He says that he did this by eliminating subroutines unused by the calculations we are running for the Institute for Systems Biology, so the computation time is unchanged. I think you have gotten some rough proteins in your Work Units. The Institute for Systems Biology keeps track of statistical run times for different proteins and tries to 'tune' the Work Units, but this is a 'non-deterministic' computational problem.

Oh, ok, so there's not supposed to be a difference in calculation times. It seems though that the #'s in the application window change more slowly than they used to. Is this affected by the decrease in memory, and does it mean that the application is running more slowly?

And if you look at the overall statistics that's true because there arent less points generated. It might turn up you just have a long wu. Then the % is updated more slowly. grtz |
