Large folding operation - Page 2

post #11 of 14
Client choice is a tricky one really - you would really want to run the SMP client, but you need to fold for at least 8 hrs or so a day on a dual core to make the deadlines (this won't net a lot of points anyway, but there's no benefit to the project to have loads of clients requesting units that they fail to complete in time).

It sounds like you'll struggle to guarantee that you can run long enough to meet those deadlines, so a single core client per core might be better for many of the desktops. Unless of course the Dean approves running the machines all night...

Any machines on 24/7 should be running the SMP client. It might also be worth putting the SMP clients on any 'favoured' machines in the lab - there is usually one or 2 machines that are the first to be used and are thus on longer than the others. Similarly the master and any quads should be running SMP.

It sucks, but every machine needs to be the same (i.e. running the same client, etc). I would love to use the SMP client, but I can't guarantee every machine will fold for at least 8 hours/day. Plus, they are used a good bit, so that needs to be factored in.

I am a science major (the dean and building that we would trial in is the business major's building), so I don't know much about the dean or how to "convince" him to let us run 24/7. I do know that he is really into energy conservation, so we will have to give him raw data of power consumption from one of the computers for him to see.

If this one goes well, or if the dean shuts us down, we might try out the one in the science building. The dean there is much more relaxed and would probably be ok with us folding there (even though there are only 15-20 there).

Also, how hard would it be to have the master computer be able to "split" the WU so each computer only has to complete a fraction of the WU? Is this impossible and do I need to rid the idea completely from my mind? I always figured that there would be a way to split a WU so that individual computers (in this kind of setting) could contribute to large operations.

Does anyone know of another campus that has a folding initiative that I might be able to contact? Wild guess, but worth asking.

This won't work - a WU is already a tiny part of the overall process. Breaking it down across a cluster would kill performance due to the network latencies etc.

Bummer. We'll make due then. Might be able to get our local electricity provider involved, and sell us cheap electricity during the night. They love to have their name in the newspaper.
