Asteroids@home had a problem with their validator. It decided all work uploaded was invalid. The project staff have restarted it and it seems to be behaving now. At one point I had 380+ work units marked as being "validation inconclusive" and then it sends them to another user.
Despite this glitch I just passed the 1 million credits milestone for them about 15 minutes ago. I will now allow a spread of projects rather than concentrating exclusively on Asteroids.
With the cooler weather I am allowing the Intel GPU machines to crunch 24/7 rather than just overnight. My GPUgrid crunchers are also running but only overnight.
Hardware-wise I am looking at replacing the Drobo FS with a Drobo 5N. It is basically an updated FS with the addition of an mSata connector to allow an mSata SSD to be attached, thus making them faster.
