Sent an email to Graeme, hope to get a response as soon as possible.

First, thanks to all you Free-DC'ers for all the cycles.
Our focus this year has been on the computational algorithms. My postdoc, Lijun Xu, has implemented several strategies to increase the simulation time, accuracy, and system size scaling.
One improvement involves taking all the important processes found at one step, and sending them back out as initial guesses at the next step. This helps a lot if the system is large enough that the processes are confined to a local region. When a process is selected at one step, any remote processes will be unchanged and returned to the server very quickly as a new valid process at the subsequent step.
A second improvement also makes use of this locality. We are testing if we can focus new searches at the current steps in the area in which a process was selected at the previous step. If this works as we expect, it will lead to linear scaling in the cost with respect to system size.
One final improvement is how we deal with fast transitions between known states. This used to be the main reason that the server would not respond to clients - it was busy simulating the dynamics between states that it already knows about. Now, we apply a statistical model to choose a processes which leads to a new (unknown state). This has significantly reduced the server dead time.
Lijun is writing up a paper on these methods, and we'll have it out this summer.
Largely based upon the results from eon, we have received a NSF grant for taking this project further (info at http://www.nsf.gov/awardsearch/showA...Number=0645497 ).
One of our long-term objectives is to use quantum mechanics to evaluate the interactions between atoms. These calculations are much more expensive that what we are doing, so that only the fastest machines with enough memory could participate. But, as computers get faster, this will eventually be possible. When we get this working, it will mean that we can simulate more interesting systems, including chemical reactions at surfaces, and the computational design of catalysts.
Thank you very much for the update.
Going to ask him for another progress report.
The project seems to be have been down for about 2-2.5 hours.
Server is now up and running.

It seems that there is a network problem with our server again. Unfortunately, it is weekend and the computer room is closed. I am contacting other people to see if we can do something about it before Monday. Lijun.
Hi all,
I know this thread has been there for a little while now.
I just wanted to drop by and say that indeed the server is up and running. This website is pretty cool and gives pretty accurate news.Simulation pret immobilier
Cheers!
Yes But can your servers give out more work I have a vary Hungry Hoard hereQuote:

ya makes you want to :cry: don't it
Guess that can't aford a good server
Yes its normal for this project. Just run as many instances of eOn as you can and eventually one of them will grab a task. I usually run 2 instances per core.
Does anyone know if a Eon user switches from one team to different team, odes his points follow the user and apply to the new team even though they were earned with the older team?
Thanks
Well Free-DC is such a Good Team :hugging: Members don't think about that kind of stuff that much :confused:
So it might take one of the Stat Masters here like Bok :Pokes: to answer that Question
The points will follow the user.Quote:

You can even get a Free :roadkill: sign when you join us:thumbs:
Thank you Laurenu2 so much . Nice day everybody^^

Good to have you here !
What are you crunching ?
Nice! Welcome. :cheers:
maybe wanted to do a bit EON for DPC
But this stopped me hard and fast
"EON Clients
Windows (559KB - Apr 13, 2005)"
4 1/2 years without an updated client :hair:
No improved code or even a better assembly. :evil:
Ps: Why isn't the eOn-page linking to this Forum.
