So after a warm week yesterday cooled off and we had a howling wind. Great for the farm though. I fired up the non-GPU cluster of machines and the GPUgrid crunchers.
Seeing as the GPUgrid crunchers have been off for a while they immediately went into high priority mode thinking that they wouldn't be able to complete the work in time. Now they are 75% through they have decided they don't need high priority. Hopefully I can get a few work units out before the weather warms up again.
We got up to 7.0.47 this week. Nothing major in this, mostly cosmetic changes and some tweaks to messages, etc. I have it installed on two machines, one non-GPU and one with a GPU. Actually the term non-GPU is not correct, they all have Intel GPU's integrated on the CPU chip.
The 1st Raspberry Pi that I got is still having issues so I have put in a request to replace it with the supplier (Element 14) in Sydney. In the mean time I have ordered two more Raspberry Pies. I have some vague idea that I would like to make a small cluster of them and use Beowulf or HTCondor if I can find a version that will run on them. I know I can run BOINC on each one of them but what would be nice if I could get BOINC to submit work requests to the cluster.
I have also been looking around for cases and power supplies. There doesn't seem to be anything out there for multiple Pi machines.
While searching I did come across one setup where they are emulating a MicroVAX 3900 on the Raspberry Pi and its running OpenVMS. They had two of them clustered together. The link is:
My one working Pi is currently trying out Albert@home work. This is the beta test project for Einstein@home. They are testing smaller size work units just for the Pi and an optimised science application. Its currently about 75% through its first work unit and looks like its going to be about 3 days per work unit. This is on a "medium" overclock as set by Raspi-config.
