Garching's new super-computer enters the race

SuperMUC No. 4 in the World and No. 1 in Europe

SuperMUC, Garching's new super-computer

Research news

„SuperMUC“, the new supercomputer at Leibniz Supercomputing Centre with a peak performance of 3 Petaflops, is ranked no. 4 in the TOP500 list of the world’s fastest computers which was published today. Garching's new supercomputer is also today’s fastest computer in Europe. Its general purpose processors allow an especially versatile deployment. SuperMUC’s warm water cooling raises the standards in energy efficiency to new levels.

SuperMUC is equipped with more than 155,000 processor cores, which deliver an aggregate peak performance of more than 3 Petaflops (3 quadrillion floating point operations per second, a 3 with 15 zeroes). More than 330 Terabytes of main memory are available for data processing. In addition, up to 10 Petabytes of data can intermediately be stored in parallel file systems. For permanent storage of user data like program source code, input data etc., a storage solution with more than 4 Petabytes capacity is available. Furthermore, magnetic tape libraries with a capacity of 16.5 Petabytes are available for long-term archiving of data.

The energy consumption of the new computer posed great financial and technical challenges to all involved parties. SuperMUC needs considerably less power than other computers of comparable performance. This considerable progress in energy-efficient supercomputing could only be achieved because the processors and the main memory are directly cooled with warm water and no additional cooling infrastructure is necessary. The cooling concept was developed by IBM specifically for SuperMUC, and for the first time deployed on the really large scale seen on that system. In addition, the Intel processors and the system software delivered to LRZ offer further opportunities to save energy. Through all these measures, the total energy consumption could be drastically reduced and thus a substantial contribution to climate protection can be realized.
