Sweden's fastest computer comes to LiU

Sweden's fastest supercomputer will again be in Linkoping. During summer the Triolith will be installed on Campus Valla, a computer cluster with the capacity to surpass its competitors by a long stretch. Researchers at Swedish universities will use the system.

The new powerhouse is one of three computer clusters from Hewlett Packard (HP), which now elevates the National Supercomputer Centre (NSC) at Linköping University. Go Virtual Nordic AB is the supplier and the purchase has been financed by the Swedish Research Council (VR) through the Swedish National Infrastructure of Computing (SNIC).

The largest system, Triolith, contains 1200 calculating servers and will theoretically retain a calculation capacity of 338 teraflops, which means that it can carry 338 trillion so-called floating-point operations per second. So it surpasses the supercomputers at the Royal Institute of Technology (KTH) and the Swedish national authority for signals intelligence: the National Defence Radio Establishment (FRA).

“We are pleased and proud that NSC can now offer our users an even more powerful system. It provides Swedish researchers the opportunity to perform calculations and simulations on a level not previously possible,” NSC's director, Professor Bengt Persson proudly explains.
He continues, “The calculation needs have increased tremendously in recent years, in physics, chemistry, biomedicine and even other life sciences, where large-scale data can now be effectively analysed.”


According to Sverker Holmgren, the director of the Swedish National Infrastructure for Computing (SNIC), the Triolith amounts to a substantial contribution to the national infrastructure for scientific computing.

“There is a rapidly growing demand for increased computing power for Swedish scientists and the new computing resource at NSC will enable new and interesting research, "says Sverker Holmgren.

The first and partial installation will take place between April and May 2012, and then the complete system will be installed after the summer. As Triolith becomes operational, the NSC will phase out its previous largest computer systems, the Neolith.

Simultaneously with the Triolith installation, the Krypton system will also be installed, a computer cluster with 240 computing servers. Krypton is financed by Swedish Meteorological and Hydrological Institute (SMHI) and is intended for climate research and the development of forecast models. The third computer cluster with 72 computation servers is intended to satisfy Saab's needs and after a short stay at NSC it will be installed there.

The hardware in all three computer systems consists of HP's scalable modular chassis, ProLiant SL6500, each armed with eight computer servers of the latest model. Each calculation server houses two Intel Xeon E5-2660 processors, each of which has eight processor cores with AVX instructions and four memory channels populated with DDR3-1600 memory. The servers are connected with Infiniband FDR (56 Gb/s) from Mellanox.

In Triolith, 1144 of these servers are equipped with 32 gigabytes of memory and 56 with 128 GB of memory, a total of 42.75 terabytes of primary storage. The total theoretical performance of Triolith at nominal frequency, 2.2 GHz, is 338 teraflops. The corresponding performance of Krypton and Saab cluster is 67.6 and 20.3 teraflops.
