19th of June

Well its been a fortnight since the last post. I managed to pass 38 million for GPUgrid and 8 million for Einstein.

BOINC testing
We have 6.12.33 to test at the moment. Not much different to the previous couple of versions other than bug fixes. I have put it on 3 machines at the moment, the others haven't been updated from the release version (6.12.26) yet.

Farm news
There is a new optimized GPU app available for Seti (known as x38g), which is somewhat faster than the previous optimized GPU app (x32f). It caters for the newer V7 format work units which will be introduced later this year, as well as handling the current V6 format. It requires cuda 3.2 capable drivers to be installed, which I already had. I have it running on the 2 machines that do Seti work.

I am running the cache down on all of the machines as I will be taking a trip soon. The farm will be off while I am away.

Project news - GPUgrid
They brought out a revised app known as 6.14 for cuda 3.1 capable machines. Unfortunately they set the task priority to Above Normal so the whole machine is sluggish. Their main developer has gone off on a 10 day (work) trip to the US, so we have to put up with it for the next week or two.

Project news - Seti
They have been having network congestion issues for the last week or so. Now they are starting to run low on the data to send out due to having a whole bunch of short work units. They can't get their raw data off their backup and split it into work units fast enough.

Last week they did their Green Bank observing and have lots of data to process. It will probably require a new application as their data format is slightly different to what they get from Arecibo. We might get to process this data towards the end of this year depending on how fast they can come up with a new science application.
