And another research contribution tracking thread added... science number 17. Let's see if the scientists can tell the audience on Announcement day we've already done hundreds of CPU years worth. With Zero Redundancy distribution we should have no trouble to see the first blip on the scales.

What a wonderful graphic, Sekerob! Can't wait to see the lines and bars start appearing...

Does anyone know how long this project is expected to last for on WCG? I like to try and plan my crunching, and having a rough idea how long it'll be around for will help me plan what project to crunch and when.
P.S. any chance of resurrecting the project completion bar chart Sek?  |

Yet another cool graphic Sek. All I need now is my 3D glasses and my blacklight

Sadly from my desktop to photobucket some of the resolution goes lost.
----------------------------------------On run time I can recommend to read the Research links and also the FAQ's... there's a section on Run times and a piece that reminds of what we're currently doing with DDDT2... lots of verification and validation needed, which is good... we don't want to do a million years as mentioned somewhere else and than learn it has to be put back on the drawing board. From Help: http://www.worldcommunitygrid.org/research/c4cw/faq.do Crunching on, 5 valid, 2 inconclusive. Versions 6.12 and 6.13 (for Linux only).

Sadly from my desktop to photobucket some of the resolution goes lost. Seriously, looks good even on my "Cheap As I Can Get It Without Shoplifting" VGA moitor in the server room. Looks great HDMI |

Does anyone know how long this project is expected to last for on WCG? I like to try and plan my crunching, and having a rough idea how long it'll be around for will help me plan what project to crunch and when. From Sekerob's link. How much computing power does this project need, and why? Based on the molecular dynamics simulations that the researchers have done up to now, using a cluster of 20 nodes (160 CPU cores) for a couple of months at a time, they estimate that to extend the simulations to water-flow velocities typical of practical nanotube filters, they will require another factor of 400 or more in compute time. And to simulate a representative range of membrane pore sizes would require a further factor of 10, for a total of order 106 thousand single-core-CPU-years. Add on to this a wide variety of contaminants they would like to add to the water in the simulations, and the sky is the limit! Of course, the researchers will have to go one step at a time, and a lot of the computing effort will be to verify previous results at each stage and to make sure the results are reliable.

We were able to do only 80 days worth of work on the 1st day (of course it isn't a full day), but every journey starts with a single step. I bet tomorrow we will do at least 200 days worth

I bet tomorrow we will do at least 200 days worth You read too fast: it's not 80 days but 154, and if there are not at least 10 years tomorrow night I will be disappointed.  PS: You read the average which has always been computed based on one more day.  After one month it does not matter too much (although it is still wrong), but after one (incomplete) day that makes a difference. ---------------------------------------- [Edit 1 times, last edit by JmBoullier at Aug 24, 2010 1:46:08 AM] |

ok, thx. That made a lot more sense, since I was wondering what the heck? I mean 80 days? I did 17 days myself, so with only 80 days, that meant I did over 20% of the work.
----------------------------------------154 days is better, but lets face it the main reason is that a lot of people have to finish up their cache first. |
