DescriptionAchieving exascale-level computing requires innovations in all aspects of computing from novel chipset designs to datacenter construction. Exascale debates typically revolve around novel architectures that would be capable of exascale computing. Importantly though, faster typically is synonymous with more power. It’s estimated an exascale system would need somewhere in the 20MW range of input power to run. Most datacenters do not have that amount of power to dedicate solely to computing. Therefore, a holistic datacenter design approach is just as critical as to the underlying technology inside the datacenter. Lenovo has partnered with Leibniz Supercomputing Center (LRZ) in Munich to attack the datacenter challenges starting with an efficient liquid-cooling approach that removes internal fans. The next generation of innovation involves utilizing absorption chilling to produce chilled water using the heat exhaust from computers. In essence, the heat that the computer system generates is responsible for creating the chilled water needed to cool other systems in the datacenter. By implementing absorption chiller technology in conjunction with liquid cooling, Lenovo has moved closer to a solution that will ensure the power required in exascale computing is delivered as efficiently as possible.
