Hi,

I'm running Rosetta 5.25 on BOINC 5.4.9 on a Windows XPSP2+ patches system (what an introduction :) ) and it eats up 180MB of RAM.

Can this be correct? Other projects use a lot less than that.

Thanks for your suggestions.

Hi FoldLikeCrazy

Welkome to Rosetta.

The work unit you are crunching is large and takes that much memory.

On this page you can se the size of CAP targets http://predictioncenter.gc.ucdavis.edu/casp7/targets/cgi/casp7-view.cgi.

Most of the targets do not need that much memory. :)

Yes, the larger proteins take more memory. There's more to keep track of as Rosetta winds it's way along the chain.

The minimum memory requirement for the project used to be 512MB, but they recently reduced that after making headway and improving the program to conserve memory.

You will also find over time that different WUs for the same protein have different memory requirements. This is because some WUs are created to attempt different approaches to solving the structure. After preliminary crunch work is done, they sometimes are able to assume certain portions of the backbone to be a specific structure and thus focus the search on other parts of the structure. This let's them crunch more models faster, and to focus on the area where they now believe the solution will be found.
