28th of November

Nothing this week.

Future plans
At the moment I will look at getting a GTX570 to see how they go. If the GTX570 seems to be reasonable (price/performance) then I will look at one for each of the i7's except Maul. They will replace whatever each one has (2 x GTX295, 1 x GTX275 and 1 x GTX460). The GTX460 will get put into one of the quaddies.

Project news - GPUgrid
They have updated their science application program to cuda 3.1. However it crashes on my machines with multi-gpu cards (ie Kirk and Sulu). They both have GTX295's installed. I have ceased running GPUgrid on them for the time being. I suspect this is caused by a bug in cuda 3.1 where it gets confused as to which device is running the app. They are in the process of creating a cuda 3.2 app so this may resolve the issue, but its not ready yet.

They are also seeking donations so they can get a GTX580. They are available from their supplier (in Spain) from the 1st of December. I made a donation to help them get one.

Project news - Seti
Well their two new servers are in. One has been fired up as the BOINC database server and the other is set to become the science database server. They are expecting to copy the science database over to the new machine next week.

Its been fairly warm and humid most of the week. As a result all the machine have been switched off during the day. This of course means not much work is getting done at the moment.

Add to this some ClimatePrediction work that takes 250 hours a work unit and it makes things a bit more complicated. I have been favouring the machines with CPDN tasks to try and get them all finished.
