OK, Harvard Research Computing has restored its services and we are back online. Sorry about the problem. Please let us know in case you experience further issues with uploads.
Best wishes Your Harvard CEP team |

This project is a little more demanding than some on hardware. But, I believe it is worth it. I first got into WCG because I needed to do long term stability tests on my equipment and felt like I was just wasting energy running Prime 95 for days. I've always been interested in solar and wind energy and have put together a few hybrid systems for off grid cabins so this was a natural for me. I recently started concentrating on CEP2 (and HCC for GPU) and now have over 6 years total run time. I really like the updates and try to read every thing you post and follow the links.
----------------------------------------Is there any though or plans to code a GPU project for CEP2?  |

Dear B2I,
we have discussed this issue in detail in various threads on this forum - feel free to search for the GPU keyword and you can easily find the entire discussion. The bottomline is that yes, we would like to use GPUs, but it's technically very challenging, and since we have many other things to do there is no active work on this. Best wishes Your Harvard CEP team |

Is there any though or plans to code a GPU project for CEP2? Harvard's answer is always the same: No. Which, of course, doesn't preclude arranging the funding and resources from somewhere else (say, the combination of CMU, AMD, and 3M) and taking a GPU-intensive approach.The impact of energy constraints - and the impact of burning carbonaceous forms of energy - are waxing, not waning. |

My time for CEP is 179days 11hr for some weeks now. Is the project dead ?

Looking at his badges, I think he is referring to CEP2. At 179 days, 11 hours he is 13 hours short of his Ruby badge.
----------------------------------------No the project is not yet over. I've been getting a steady supply (my settings allow 2 at a time in my queue). I recently rejoined WCG recently so am still waiting for my first badge. Eve [Edit 1 times, last edit by Former Member at Oct 22, 2012 2:10:48 AM] |

Yes indeed, I talk about phase 2. I'm still at 179 days, 11 hrs. Several later projects are at more than one year, or 2.

Vep, you have to convince me [us] as to why your client(s) is not fetching CEP2 work. The way to do that is go to the device-profile and select CEP2 only and select down below there to receive at least 2 **. When you've done that, hit update in the client and then post the message log, which will likely give some information why CEP2 is not being send. Generally, if selected, CEP2 is send by higher priority. If you specify 2, the servers will try to make sure that your client always has 2, as soon as there is enough space in the buffer that is set in the client.
** This will override any bandwidth limitations your client may have [it's always as fast as the slowest router in the chain between Toronto WCG servers and where you are]. Where I am, the clients need at least 15 router hops to get to the WCG servers. The minimum internet speed requirement is a consistent 64KB, as measure by BOINC. If you don't have that speed, and only specify to have just 1 CEP2 task [default], then none are send and a warning appears in the message log, but only if CEP2 is exclusively selected. If not, the servers just send the other project tasks you've picked. |

There we are, work for CEP2 eventually arrived.
