13th of March

Nothing this week, although I am close to 50 million credits for all projects.

It stands for Quake Catcher Network. Its a BOINC project that use a motion sensor (either in a laptop or attached via USB). Last week I ordered a couple of USB sensors. They come in kit form as you can see below. Some assembly required. Actually you need to solder the 4 wires onto the circuit board and then put it into the plastic box. The circuit board is approx 1 inch square.

So mine is now setup, although not in a very good location at the moment. The software runs within BOINC as a non-CPU intensive app (doesn't seem to use any CPU according to task manager) just monitoring the sensor.

BOINC testing
We got up to 6.12.18 this week. Its mainly fine tuning the notices and work-fetch at the moment. I've put it on a couple of machines and its working okay for me.

There was one user who has a 160 CPU machine that doesn't seem to be able to get more than 60 CPUs recognised. If only the rest of us had this problem :) It seems Windows groups the CPU's into processor groups of not more than 64, so scheduling tasks across all of them is somewhat different than a smaller system.. They have made some coding changes to allow for this, but we will have to wait for another build.
