So far returning just the one work unit for 326 points, his computer sits 786,306th out of 1,149,702 all-time folders. Good stuff mate.
Straight from Vijay:
"We added the word "written" to this sentence:
"You may use this software on a computer system only if you own the system or have the written permission of the owner."
We felt that this was an important addition in order to avoid any confusion. There have been a few situations where donors felt that they had permission, but the owners of the computers did not. Having written permission is the best way to make sure that there is no doubt. It also gives protection to the donor in that he/she would then have proof of permission, avoiding problems involving oral agreements."
I'd like to re-affirm that you could find yourself in a situation of getting sued for installing and running this program unauthorised, as many people have gotten into trouble setting up multiple computers at they're place of work (such as a school I.T. Administrator setting up tens to hundreds of computers) when they weren't authorised to do so, and have in some cases been ordered to pay damages for things such as increases in power bills, internet bills etc. Also, not having sufficient knowledge about the program and how it can affect different computers etc. (such as Notebooks being advised to run at no more than 90% CPU usage due to their less than optimal cooling systems) can lead to a bit of a blame game as far as what caused the computer to pack itself in and who is going to pay for it!
So guys, make sure you get written consent to run Folding@Home on computers or machines that are not your own. And be sure to inform those owners or bill-payers of the potential to have slightly higher power and internet bills whilst running this program (not a big deal for one or two machines, but any more, the extra power and internet usage quickly adds up!). Providing you do the right thing by the owner, i'm sure they will enjoy helping out a Distributed Computing Project such as Folding@Home.
A collaborated effort between the Folding@Home and Sony Development teams, this is the first paper resulting from the Playstation 3's involvement in the Project. The paper is more of a 'how does it work' with details about how the PS3 accelerates simulations through use of it's powerful streaming processor, the CELL Broadband Engine.
The abstract reads:
"Implementation of molecular dynamics (MD) calculations on novel architectures will vastly increase its power to calculate the physical properties of complex systems. Herein, we detail algorithmic advances developed to accelerate MD simulations on the Cell processor, a commodity processor found in PlayStation 3 (PS3). In particular, we discuss issues regarding memory access versus computation and the types of calculations which are best suited for streaming processors such as the Cell, focusing on implicit solvation models. We conclude with a comparison of improved performance on the PS3's Cell processor over more traditional processors."Papers of this type not only help the Folding@Home team at Stanford, but can potentially help many others outside of the Project. Whether it helps out others involved in the field of Molecular Dynamics, or people that intend to use and program for the CELL processor, knowledge gained can be knowledge shared!
Due to a bit of downtime, after needing a re-format/re-install, his computer unfortunately didn't tally any points for our recent November = 2nd Team Birthday Foldathon. However, his got 4 services of v5.04 text-only console client running on his quad-core again, and should see a pretty consistent return from him now.
Currently on 13,736 points from 50 work units, he sits 186,173rd out of 1,149,041 all-time folders. Well done mate.
With one work unit currently to his name, brolli55_ps3 has made 450 points, and sits 729,857th out of 1,149,041 all-time folders. Good stuff mate.
