 I think Hypernova, skgiven and I have more GPU's than that. Such a lonely single-leaf bronze badge.  "Cowboy Up", Harvard.   |

From 84 current Harvard members (90 in total): Harvard University, 52years 152days. Harvard Humanist Community, 13days. Almost Brown! Harvard Chemistry, 9years 169days. [url==http://www.worldcommunitygrid.org/stat/viewCompareTeams.do?teamNames[0].value=Harvard+University&teamNames[1].value=Harvard+Humanist+Community&teamNames[2].value=Harvard+Chemistry&teamNames[3].value=&teamNames[4].value=&teamNames[5].value=&teamNames[6].value=&teamNames[7].value=&firstLoad=false]Link Team speach. You might want to turn your systems on every now and again Maybe the members weren't properly educated about CEP2's long periods between check points. Maybe they have 10,000 systems up and running CEP2 but they turn of their systems off every 3 hours or so and have to restart over again and again.  |

Who says the CEP2 individuals belong to the Harvard teams previously stated or any other team? No known requirement exists (legally, morally, ethically, or contractually) for this to occur.

Hi everybody,
As you may have noticed, we have been rather busy these last weeks and hence been relatively quiet here on the forum. Sorry about that and thanks for your patience! Today we try to catch up on some of the discussions which have come up in the CEP community: About ‘Jabba’, our 90TB storage array: It is correct that discs get cheaper over time. Nontheless, we think that Jabba is a good choice for CEP. We currently collect 250GB of data per day and this may grow to about 500GB in the future. In addition there are RAID, backup, and processing space requirements, as well as storage needs for other work in the Aspuru-Guzik group. We project that CEP2 may accumulate about 0.5PB of data overall. So there is certainly demand for storage. The backblaze design is quite amazing from a cost perspective: Our Ms Piggy 1 with 24TB was about $6400 last summer, Ms Piggy 2 with the same setup had dropped to $5100 by the end of autumn. Jabba will now probably be less than $5000 for 90TB – it’s hard to beat that. We unfortunately have to fully load all 45 hd slots and use uniform hds – otherwise we could buy the drives on demand. But we do build one Jabba at a time to make use of cheaper/improved hardware – we expect we’ll build another one by the end of 2011. About the project end: Our current guess is that we have work for at least another 2 years or so. The project end very much depends on how everything works out. Theoretically, this is open-ended research because there is an infinite number of potential OPV candidates. Practically, there will come a point where we have learned all that we can expect to learn or where we simply drown in data – that will then be the point to wind CEP down. We hope you still don’t delay crunching as we can use every contributor we can get .About our own badges: Zing - Good one! To our defense: ‘cleanenergy’ is actually only our communication account. The whole team has their own ones (unfortunately, many people forgot to add their accounts to the department team - we are working on straightening this out ;)). But we concede that it looks bad, so we’ll redirect a couple of devices to collect some accolades on our official account  . Dear Aaron: Thanks for your post from Feb 5 – that was really nice to hear! We are also very grateful about the positive feedback from you guys – this interaction is a lot of fun for us as well. Best wishes from Cambridge, and – as always – thanks for crunching! Your Harvard CEP team P.S.

Nearly forgot to report: The CEP2 team had an interesting discussion with Nicholas Melosh from Stanford University last Thursday. He visited the Harvard Chemistry Department and later gave a talk on 'Combined Heat and Light Solar Conversion via Photon Enhanced Thermionic Emission'. It's great to have this constant exchange with other researchers from different backgrounds.

We had our monthly phone conference with the IBM team today. Everything seems to be in good shape and order! Since the start of our participation drive we found a nice increase of returning results – not quite yet where we want to be, but getting there.

I would expect the participation to gradually and steadily rise:
----------------------------------------First off, your communications are good. Thread participation is always appreciated and encouraging. The efforts made to facilitate crunchers are very noteworthy. New systems get purchased regularly and people tend to get faster CPUs with more threads and more RAM (certainly enough to participate to some extent). DDDT2 released a batch of tasks recently. It’s another resource intensive project but intermittent. Lastly, when HFCC starts winding down (around 3months roughly) there will be one less project (unless another one pops up). Although the overhead on HFCC is not as high as here, it is nonetheless fairly large. For some people, its too much to participate for HFCC and CEP2, and for others they just want to reach their points/badge targets before the project ends. These people will want to do some CEP2 work when HFCC finishes. It would be useful if individuals with systems capable of running many CEP2 tasks could help out other crunchers in some sort of system swap, whereby one cruncher crunches for another and vice versa. Perhaps teams could organise this themselves (through casual communication or possibly a team challenge event, % increase in CEP2)? I think it would be some challenge for WCG, the design/setup would be hard enough (web page sign up) but the account security aspect (no idea how that would work). What do you think?

Typically WCG launches 3 new researches or phases per annum. The scheduler, last shared with CA's in October, indicated that some "longer inactive intermittents'' might even be diverting attention and offer opportunities to catch up on a missed level... in short, work on what's active now :D

As you may have noticed, we have been rather busy these last weeks and hence been relatively quiet here on the forum. Sorry about that and thanks for your patience! Are you kidding? You provide more good information in a week than many projects do in a year(s). Keep up the good work.  About the project end: Our current guess is that we have work for at least another 2 years or so. Give us a GPU app and we will have you "on the beach" by Xmas.  or where we simply drown in data We can do that too. About our own badges: Zing - Good one! ...But we concede that it looks bad, so we’ll redirect a couple of devices to collect some accolades on our official account. Good move!  Good job.  |

About our own badges: Zing - Good one! To our defense: ‘cleanenergy’ is actually only our communication account. The whole team has their own ones (unfortunately, many people forgot to add their accounts to the department team - we are working on straightening this out ;)). But we concede that it looks bad, so we’ll redirect a couple of devices to collect some accolades on our official account . Perhaps one way around this, is in your 'cleanenergy' Forum profile, where there's a field for the City/State/Country details, you could put in words to the effect "Part of the _______ team" (and of course, ensure that all your colleagues are in that one team). At least that way, everyone will be able to see at a glance as to how your over all team is doing in terms of contribution to your own project   |
