So the NPR report on CEP2 came a bit later than suggested, but now you can check it out here:

I'm amazed that the clean energy project has the lowest share of computing time out of all the projects. Certainly drug and cancer research is valuable and important, but I can't imagine they would have the kind of revolutionary global impact that cheap, efficient solar cells would have.
In my mind only the only project that might compete in terms of long-term benefit to humanity would be the computing for clean water project, though even that wouldn't enhance personal empowerment the way that being able to cheaply produce one's own green energy independent of the grid would. Oh well, I suppose that's just the utilitarian in me. As you've said, all the projects here are tremendously beneficial and worthy causes, and ultimately people should contribute to the projects that resonate best with what they feel is important. |

The problem with the low participation is because checkpoints on CEP2 can sometimes be hours apart which means if you shut down your computer it will go back the to the last checkpoint which sometimes means loss of several CPU hours. Another problem is the disk access.CEP2 uses a lot of the HDD and thus running several CEP2 Wu's at a time seriously degrades performance.Add this to the high memory usage and the opt-in feature for CEP2 and you have a small cruncher participation.

One other item would be the large 20mb+ uploads for each completed WU. If you do not have the bandwidth, these can take a long time. Cheers

Frankly, I was taken aback by putting to public debate the WCG limitations from the project
----------------------------------------WCG goes the safe route: We shall NOT knowingly impair the user, individual and equally certain not those that have large number of devices volunteered in company offices or colleges. The uphill battle to get partners such as MakeCuresHappen to contribute their fleet is huge, from security and user experience point of view. Bandwidth costs money too and when moving CEP2 on and off thousands of devices, through central external connected nodes [springs to mind a company with 25000 devices in near 200 countries and only 4 points going outside their global LAN], very major bottlenecking could occur, national and cross-ocean. So, lets not get greedy and cheese the decision makers off, small or large. --//-- edit: strike members to avoid confusion whom talked to, replaced by 'owners.

Clean Energy if you don't mind. Can I use some of those links on other places. I subscribe to a few other 'news' outlets, being in the power industry and all, one of them centralizes on clean energy, and specifically smart grid, power generation / distribution. If I can get them to put a plug in on one of the newsletters / daily e mails etc perhaps we can get a few more participants.
Thank you. Aaron |
