My work PC has been crunching Predictor and Simap for a while when I noticed the I/O volume that those programs require. As a rough guess, Boinc was downloading at least 16 to 30 Megs per day (probably uploading much less). My concern is eventually someone in IT will notice this unusual traffic and wonder if I'm D/L'ing gobs of porn or if I'm part of a botnet, then start investigating. Dunno if this is a concern for other corporate resource-stealers Cool or if I'm just paranoid... Shocked

To maintain a low "profile", I'm running just CPDN, figgering it's extremely low I/O, getting a new WU only once every few months. However, I have a P4 that allows Boinc to run two projects at once so it's using only about 50% of processing capability. This system is SINFUL, it is WASTING SACRED COMPUTER CYCLES! #evil

I s'pose I could also run the BBC climate change project, but I'd rather have more "diversity" on this system. So are there any other low I/O programs you can recommend?

Try Rosetta@home, it's lie predictor but you can set the WU runtime up to 24 hours each ......

Climate is low i/o until it reaches the end of a phase. Then it uploads .5 gig and up, depending on how good the compression is and which phase just finished.

Rosetta would probably be ideal as was mentioned by Sir Brian

QMC WUs can also take a lot of crunch time, as of late it seems uFluids is as well... Then of course, there's Rosseta as has been mentioned, along with RALPH, though RALPH being the alpha project, obviously won't have a consistent stream of work (only when testing is needed). RALPH also has shorter deadlines, to allow for quicker testing and all...

If you want to go the CPDN route, seasonal attribution might be more ideal, though not sure how bad it can get. The WUs are much smaller then CPDN main, taking about 15 days or so on an A64, so I'm guessing don't have the large uploads at the end of a phase like a coupled ocean model does. However, it does have higher memory requirements, aka you should have at least 1 GB of RAM to run it (as recommended).

Rosseta, probably would be closest to what you were doing (type of science) to predictor itself...
