ICARUS survives first night on battery
After its installation in the solar-powered container and its connection to the insular power supply system, ICARUS was set up to be in 'ready'-mode this Thursday night, relying solely on its 8kWh battery supply after a full charge. The next morning, it turns out to survive a cold March night with no additional heating, staying at a modest average 20 degrees Celsius. The cluster (that is 55 out of 61 nodes - some are under maintenance - plus 5 switches and control hardware) drained only slightly above 300 W of power at all times. In addition, we had a 1kW heating module for the battery on-line (thermostat-controlled set up to hold the battery above 5 degrees Celsius in order to prevent damage). At first sunlight, the battery was discharged down to 40%. Next task: load battery, while in 'slight use mode' today, a very cloudy, cold and foggy day in Dortmund. The problem here is: can we load the battery while powering the cluster even on days with low sunlight harvest?

ICARUS installation in its new home
The cluster has moved into its final housing and connected to the solar power system. First burn-in tests have been successful!
TU Dortmund is awarded GEC again
We just received word that the TU Dortmund is again rewarded the title 'GPU Education Center' due to CUDA-related teaching activities of our institute. ICARUS has played a role in this, because of a student project that was built around it.
First test of the energy supply systems successful
On a bright friday evening, a successful first test of the solar power supply and the battery system was conducted. Although half of the solar modules were shadowed (as the system is not winter-optimised) we were able to measure a nice 3kW for a short time.
