Hello Jim1348,
Here s the link to the Harvard Team's response to utilizing GPU's on their research project. Tedi |

Johannes was invited by the Cote Group to give a seminar about the Clean Energy Project at the University of Montreal on Monday.

Dear Jim1348,
The checkpointing and parallelization are two different issues. Quantum chemistry can be parallelized and can also be rewritten to work on GPUs but to get this going on the grid is a lot of work. At this time, it is just not a priority for us since we have more important work to do then utilize this additional resource - in such a big project one has to make such choices. But the topic is definitely still on our radar. Best wishes from Your Harvard CEP team |

A very interesting article in The Daily Climate on the prospects of and challenges for organic photovoltaics. While not nearly comprehensive in its discussion, it points to some of the important promises this technology has to offer and the problems that still need to be overcome to make it a viable source for renewable energy. Oh yes, and Alan was quoted

Today we want to highlight a cool World Community Grid achievement: the WCG cracked the mark of 2 million registered devices! This is an awesome supercomputer.

I do not want to burst anyone's bubbles, but I do not believe that these statistics are accurate. I believe that WCG's Global stats include any and every person and host that ever was, including the old U.D. days.
----------------------------------------I believe that you will find a more accurate reading at BOINCStats, especially for current users and hosts. Of course, BOINCStats in their total summaries only include those users and hosts ever on BOINC, not U.D., thus the divergence in the totals for all time. I personally will not bring this response to Facebook. To me, it is dirty laundry to be kept in house. I have considered what I see here as a purposeful discrepancy to be very irritating. I have complained to WCG myself more than once about this. WCG has nothing to apologize for in its current numbers. If anyone wishes to correct me in any of the above, I would be only too happy for WCG. |

What difference does it really make if the number of users is off a few, or a few thousand for that matter? Nobody is getting paid to participate, nobody is being robbed of a comission or 'downline'. The thing that does matter is that a lot of people are donating computing power to accomplish a goal for humanity.
I think it much more important to have the developers work on making the program faster, more efficient, more effective, and not worry about silly little trivialities that honestly have absolutely no impact in the final scientific output.... or input if you want to split hairs. Just my opinion. Aaron |

I would be a lot more concerned about the accuracy of the numbers if WCG were preparing an IPO and revenue generation were based upon "current users". As they are indicating the number of individuals/computers which have been used by the WCG, the existing numbers are accurate enough - in my estimation.

I really should ignore this post but like a moth to the flame.............................
I do not want to burst anyone's bubbles, but I do not believe that these statistics are accurate. You are full of air. The point being made was that we passed 2M total registered computers, which we have. Anybody who has the ability to click a mouse can see the number of devices is 2,005,761. Try it. It's really easy.If anyone wishes to correct me in any of the above, I would be only too happy for WCG. You pose a contradicting opinion that has no basis in fact, only conjecture and rumour. Your statement disparages the author and is quite disrespectful. The 2M is just a number. If the REAL number is something different who really cares?. The same can be said about whether my 64,940,966 points REALLY represents 92.772 TeraFlops. Life is too short.  |

 Right, mtrichr. This was a topic back in 2005. Unfortunately, the total number of registered users and devices is quite correct, but bears no relationship to the much smaller number of computers that have returned work units in the last 14 days (or 30 days or whatever). Look at YESTERDAY under Global Statistics and convert run time to hours, then divide by 24. Or even easier, look at the BOINCstats site for info. The Global Statistics were very good the first month, then slowly diverged from anything useful. I have not bothered saying anything about it since 2006 or 2007. First convert to BOINC credits. Then start talking about this embarrassment. Sigh . . . Lawrence |
