It seems that the expected size of a WU is a parameter known to BOINC, since it is used to determine if there's enough disk space to download WU's.

As far as I can tell, Rosetta is way overestimating this size, which causes a slight problem for me. A couple of systems I have, run with fairly small disk drives (300 megs or so). I did a trial, and D/L about 5 days worth of work to my desktop, and found that the 14 WU's it downloaded, together with the other assorted BOINC files, occupied a grand total of 25 megs

However, to get this to happen, I had to lie to BOINC and tell it that I had in the order of 10 GB free space. Since the "small" disk systems can't ever have this much free disk space, this means that I won't be able to D/L Rosetta WU's to them, which in turn means they won't be able to contribute.

Being new to Boinc and Rosetta, I've been reading through alot of the discussions about how to set the project up. Perhaps someone else can share the link to the page I was reading... or verify if it's applicable in this situation. I ran across mention of using BOINC for multiple projects - and configuring how much cpu usage each application gets. The timeslice was related to the size of the hard drive space that that project was allowed to have, as well. I was also given the impression that there's multiple spots that refer to hard drive usage - and you need to find and adjust them all for your situation.

It would be nice to have BOINC allow max HD usage per project so that a project that only uses 1% of the cpu can have 10% of the allocated HD space. (With project based recommendations for allocated HD space.)

As for finding what I'm referring to.. I've been through the FAQ, the link to the BOINC setup hosted on SETI's forums, and some of the question forums here. Hopefully, this will remind someone so they can give you a link..

I have a simular problem. I am trying to run BOINC from a RAM drive. That part is working just fine. But I am running into the same issue at you are. The Rosetta jobs don't take too much space but they reserve tons for the download. This is my current settings:

Disk and memory usage
Use no more than 100 GB disk space
Leave at least 0.0 GB disk space free
Use no more than 100% of total disk space
Write to disk at most every 668 seconds
Use no more than 99.9% of total virtual memory

I have the RAM drive set to 408Megs with 357Megs currently free. I haven't looked too much into it but I was thinking of downloading the source code and putting in a cheat. If it is Rosetta asking *10 the free disk space.

I can make the RAM drive bigger but where does it stop? I have 2Gigs of RAM on a dual Xeon system running Windows XP Pro.
