IBM, in collaboration with the Leibniz Supercomputer Center in Munich, is using hot water to its SuperMUC supercomputer.
This is not new for IBM. It had used the technique way back in 2008 to cool Power 575 supercomputer. However, the new technique, with significant improvements from the earlier one, is touted as an innovative way of energy saving.
The system, called LRZ “SuperMUC”, is based on an IBM System x iDataPlex Direct Water Cooled dx360 M4 server. It is said to feature 150,000 cores and provides peak performance of up to three petaflops. In layman’s language it could be described as something equivalent of the processing power of 110,000 personal computers.
IBM claims that the technique needs 40% less energy to cool this machinery as compared to the other air-cooling systems. The heat is then used for the heating systems of the Leibniz Supercomputing Center campus. This accounts for an annual savings of $1.25 million on their heating bills.
Bruno Michel, manager of Advanced Thermal Packaging for IBM Research said that the hot-water cooling technology helps to reduce the size of the system by a factor of ten. The team is hoping to improve the design by reducing it to the size of a desktop with zero emissions.
We expect IBM to come up with such impressive and revolutionary improvements soon. Here is the video of the new system, watch it to know how it exactly works.
