Everyone can crunch as many ''full active'' WCG research work units of one or the other without impeding any other member i.e. no one is taking away from anyone.

If the multi-science mix does not get enough of one or the other science to get to a contribution target X months in the future, switch to single / exclusive crunching. WCG techs will take care you'll be getting them.

If supplies temporary stalls due a feeder crunch, just let the client do the job. It will keep asking for the researches selected until it has the cache filled to at least it's X days setting.

Feeder priorities need to be managed because the duration of tasks of different sciences vary AND members change their contribution and selection all the time. Can't put equal numbers in the feeder as else in CPU time for instance FAAH/HPF2 would push other sciences to the side. If one would select a mix of FAAH and HCC, ideally one would see a ratio of e.g. 1:8 or so. If the supply is momentarily not there, it will be later backfilled with some extra. The server systems tracks how much a client does and tries to balance over time... kind of a STD/LTD (Short/Long Term Debt) method, but then maintained on the server, similar to a client tracking STD/LTD if a client is attached to 2 grids and both are set to receive 50%.

Hope this helps to take away your concern.

you are great,good night!

Do we know the percentage of the completeness and how many days left?

In the future when hopefully the results of this project will help to provide clean water for the developing world, how many of them will realise that thanks to the humble PC that they have clean water?

I'm not sure. On a stock I7 980X 3.33Ghz a target 04 task with HT on 12 tasks running Win7 64 tasks take between 4 hours 10 minutes 46 seconds & 4 hours 12 minutes 04 seconds. If my PC runs for 12 hours I can add over 6 days of run time to C4CW. Hope this is helpful.
