biggrin The Exchange

The objective of this thread is to provide a way to exchange computer time between teams that have a bias. For example, I run a team that is HCC biased, but many of us cant run HCC without loosing efficiency. It would be better for us to run other projects. What we are hunting for is a team that is non-HCC biased and can do so without loosing efficiently to run it for us. In return, we run your work based on your bias.

Get the picture? If not, this thread and my email is at your disposal.

Re: The Exchange

A reminder for those who aren't familiar with how WCG scheduling works:

WCG will attempt to respect your project preferences. First, they exclude any projects that your computer doesn't meet the requirements for. If no projects meet the requirements, and you don't allow work from other projects, you will get no work.

Once that is out of the way, WCG assigns work based on what needs doing. If some people are opting out of one particular project, WCG will send more of those units to other people. Sometimes, WCG will increase the priority of a project to get it done quickly, or slow a project down, to allow the scientists to prepare more work, or sometimes for technical reasons, to improve overall grid performance. The grid techs have many, many variables to juggle, and the results of these adjustments can be seen in Sekerob's excellent charts.

In short, your project preferences don't affect World Community Grid's progress or overall output. They only affect what you, personally, run on your own computer.

Re: The Exchange

You are still not getting the picture. As it doesn't address the current abnormal state of affairs with the HCC project. This is just a work around to stablize the loss of work due to the 'machine dependant' nature of the HCC project, until the fix is complete.

Re: The Exchange

There is no loss of work. That's my point. Your scheme, though well intentioned, simply isn't needed.

World Community Grid is self-balancing.

Re: The Exchange

I tried a couple of weeks worth of HCC. Yes, I saw 45000 faults per second. However, the work all finished.

Re: The Exchange

Ret,

If you run FAAH or Folding, would you see the same error rate?

Re: The Exchange

There is another way to do this. I will run your projects now if you run HCC after its fixed.

Re: The Exchange

I don't think the error rate was as high...

FAAH is quite efficient here.

I have some DDD-T going now ... 2.7 million page faults after an hour, but they are few and far between. Page fault delta is mostly 0. (Were most of them at the beginning or some particular point in the process?)

Re: The Exchange

Or possibly after some hard faulting when you context switched?
