In this video, researchers from Cyfronet in Poland describe Prometheus, their new supercomputer built by Hewlett Packard Enterprise. Comprising more than 1700 servers of HPE Apollo 8000 platform and connected by FDR Infiniband, Prometheus will benefit scientists in the fields of chemistry, physics, astrophysics, biology, energy, nanotechnology and medicine.
“Thanks to the innovative technology of direct water cooling of processors and memory modules, Prometheus is one of the most energy-efficient computers in its class in the world. To maintain the proper temperature of the liquid in our climate (Poland) it is enough to use so-called dry-coolers, cheap in exploitation, instead of ice-water generators, which consume relatively large amounts of electricity. This solution will positively impact not only on reliability, but also will provide much higher performance than similar systems based on the classic air cooling. In the case of Prometheus, the Power Usage Efectiveness (PEU) factor (which for the best data centers, using air cooling, is 1.6) will be 1.06, so only additional 6% of energy for cooling is needed, instead of additional 60%. These are very significant savings. In practice, this means that the computer will use less electrical power per 1 TeraFlops. Furthermore, liquid cooling enables extremely high-density of installation of 144 computing servers in a single rack. Therefore, the computational part, weighing more than thirty tons, fits just in fifteen cabinets.”
