ICARUS survives first night on battery

2016/3/18

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?

TU Dortmund is awarded GEC again

2016/3/15

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

2016/1/8

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.
