The "farm" has been shut down for the Christmas break (as of 23 Dec), so the accumulation of credit has ground to a halt. I am still concentrating almost exclusively on SETI@Home with Collatz running on my one ATI card as I cant find a Linux/ATI app for SETI.
I have been running TilesAtHome for the OpenStreetMap project again and am just short of having rendered 2 million map tiles. I may reach that milestone by midnight if there are no unexpected glitches. There have been occasions where the tilesGen app uses massive amounts of memory which causes a massive swap file to be created and this hammers the RAID array until something breaks. I have seen a complete reboot as a result of this happening.
I have restricted the "complexity" that my system will accept but this does not seem to entire resolve the problem...
