2) Questions and Answers : Wish list : Support for BOINC - x64 version (Message 40097) Posted 9 Jul 2010 by old_user627570 Post: mo.v Can you ask someone in the Met to speak to Sir Richard Branson or Sir Terry Matthews lol. Those two guys seems very open to donations for scientific projects, I am sure they would be willing to enlist the help of some people they know in getting 64-bit and GPU support up and running for CPDN, considering Met is Britsh as well. ;)
3) Message boards : Number crunching : A comparison of CPU/GPU performance... and a message to MetOffice (Message 40096) Posted 9 Jul 2010 by old_user627570 Post: Hi everyone, I am sure this has been asked before... but where is the GPU support for ClimatePrediction.net? As things are are now, the app is pretty stable so couldn't the Met just forgoe the effort into updates that would normally come and instead focus on getting support for ATI and nVidia cards for a short while? Look at some of the figures here, BOINC forums suggest than credits work universally and so each project doesnot award points through credits which have differing scales for the amount of work done. CPU Projects: Einstiein - 1282.48 SETI - 4245.50 Cosomology - 2520.00 GPU Projects: Collatz - 208513.08 DNETC - 142324.00 Milkyway - 266558.66 So, the throughput of even old GPU's being far quicker than CPU's like Intel's new i7 is not extactly breaking news. It is open for debate how credits are issued across different projects as I have not heard anything on the subject from the project admins. It is also known that CPU's although slower are more accurate, however the sheer amount of work the GPU's get through would render that argument invalid. By the time my 4.0GHz, 8 thread i7 completed 1 work unit... the 2 HD5870's could have completed work units going into double figures. Can the forum admins shed any light into the Met Offices plans for future support of GPU's? There would be alot of interest from the community and it would be nice to see these work units with an estimated finish time somewhere around the two hour mark. :D
