300MB of RAM??

I just installed the WCG software and fired it up. According to my Task Manager, my PF Usage jumped from about 140MB to 450MB. The WCGrid_Rosetta.exe process claims to be using only 71,700K but as soon as I shut down the WCG Agent, the PF Usage drops back to 140MB.

Is this normal? Seems a little extreme to me. Are there any settings for memory usage? I can spare plenty of CPU cycles but 300MB of RAM is a different story.

Re: 300MB of RAM??

The Rosetta code running within the agent which works on the folded proteins currently allocates enough memory to handle any kind of protein. In practice, not all of ihis allocated memory is typically used for the processing of a given protein. So, this makes it allocate extra virtual memory which gets paged out and then is not used. In your case, it needed less than 100 megabytes of physical memory. We are aware of this and will be engineering modifications to the program to more intelligently and conservatively allocate memory, however, this is not as simple as one might like. When we have this change engineered and thoroughly tested, we willl have the server send out the updated program for further use in this project. You will not have to do anything since this will be fully automatic. So in the meantime, it the program will use some of your swap file space. Please bear with us until we update this.

Re: 300MB of RAM??

okay, as long as it's doing this by design and there's a fix on the way, I'll live with it. I mostly wanted to make sure it wasn't just my computer or that I didn't have something configured wrong.
Thanks for the reply.

Re: 300MB of RAM??

It would be good to fix this problem, since I do not use a swap file for performance reasons. If you run it twice (once on each processor biggrin ) it is getting a problem....

No kidding, this is too much. I had to send another note to my friends telling them to wait on this as it eats RAM like a runaway virus.
