My guess is that C4CW would run ok on your machines despite the nominal memory requirement. I can run four C4CW WUs simultaneously on a dual-core Atom with 1.5 GB of memory available to the CPU, so there is less than 400MB available per WU. This is under Linux, by the way. I've been thinking along the same lines as you -- I have really enjoyed running HCC and HCMD2 on my Atom, and I am hoping that a new WCG project will have similarly short run times. But I'm lucky that my Atom is capable of running the projects with bigger WUs if necessary, and that I live where I have been able to purchase more powerful machines at reasonable cost. Edited to add this: If you decide to try Linux, you might look into Lubuntu or Xubuntu. Those are versions of Ubuntu that have lighter-weight user interfaces and leave more RAM available for applications while still offering similar ease of use and easy access to applications as Ubuntu itself. Kate, The download criteria only look at overall free RAM availability, not per active thread. The control used by BOINC during actual execution is the idle/work RAM allowed percent. Running task(s) will be paused or not started if the insufficient RAM occurs and logs as "waiting for memory". Of course running with LAIM 'on' would risk to hit the boundary even quicker than 'off'. If this happens, BOINC will pause one or more tasks and try others in queue, but of same requirements, soon the client would do a head against the wall. So, marginal systems are not recommended to run with LAIM on if the plan is to squeeze them in. BOINC will then lower the concurrent tasks [and unload the paused ones]. It's whatever the owner wants to force through, of course there being the few that will unavoidably come up with ideas for smarter management [those at Berkeley surely had not thought off]. Well, the new BOINCs are supposed to remember how big the requirements were at start them if a C4CW never remotely come close to 400MB and will happily run on all threads or as many that fit in, 4 even though 4x400 is not met. --//-- |
