Question about project distribution

Are units sent out equally per project to someone who chooses to participate in all projects when compared to someone who does not?

In other words is it pointless to chose your "Favorite" cause if someone else on each of the other projects will receive "non favorite" work units for the other projects you didn't choose? Or will everyone else receive purely random while you only get "favorite" (thus making the "Favorite" actually get more results sent out and thus matter as a "favorite").

I just let the units fly on all projects but I'm wondering how they are calculated in comparison to each other.

Re: Question about project distribution

If you want only one project, that is what you get. Others that want all projects or a subset still get a random distribution of work among that set of all work available.

If one project runs out of work, which can happen due to human technicians feeding the queues, it is still a good idea to check the box allowing for work from other projects if you are only running one or two. If you are already selecting all projects, then that doesn't matter.

Beta work is selected from a different place, and can be from all projects that are testing something. These are usually few and far between.

Hi,

In principle, the techs try to feed an equal work amount in volunteered resource (CPU time) into the pool, but there are reasons why that can never be completely balanced, amongst very large preference for particular projects and the receiver (the project scientists) not able to take in the data quick enough (the amount in numbers or size), or a single project taking a very large part of the storage. You then have to limit the flow for those. Yesterday you may have seen the note by uplinger that RICE has resolved the data receiving bottleneck, so now they've been throttled up for more units proportionally being put into the shared memory pool... see the effect, where they got immediately 10 more CPU years, of course at the price of less work processed for the others, mostly the biggest.



Just added the percentages in the legend to indicate the current day share from the total!

No the work is largely managed on basis of work units, not time, so it's a juggling act to get the fair amount of CPU time out.

But, your choice is not pointless, because you made the contribution to the project you feel closest to. Eventually, with a large number of people doing that, you see more going to project A than project B.
