A supercomputer is a term generally referring to a machine which ranks among the TOP 500 fastest high-performance computing systems worldwide. Such machines are created and owned by state as well as private research institutions, universities, and also companies.
It can be said that every scientific field will reach the point where conventional computational resources are not enough anymore and the computation would take too long. Experiments in laboratories are too expensive, and no scientist can, in terms of money and time, afford such a number of repetitions a supercomputer can simulate. What can then be computed by supercomputers? And what computations will our graduates be able to compute using these supercomputers?
IT4Innovations runs two supercomputers – Salomon and Anselm. For educational and presentational purposes we have Permoník supercomputer available.
Salomon supercomputer has been bought in the first half of this year. It has nicely ranked 40th in July´s TOP 500. Salomon comprises 1008 computational nodes in total, 576 of which are common computational nodes and 432 accelerated computational nodes, each of which contains two Intel® Xeon Phi™ coprocessors. This fact makes Salomon the biggest installation of Intel® Xeon Phi™ coprocessors in Europe.
Our small Anselm cluster was delivered to us by Bull company. Its theoretical power is 94 TFLOPS. Anselm, the computational cluster, consists of 207 computational nodes, 180 of which are standard computational nodes, 23 of which are accelerated by Kepler K20 GPU cards, and four of which are accelerated by the newest Intel® Xeon Phi™ technology. Moreover, it contains two thick nodes with higher operational memory capacity.
Permoník is a mini-supercomputer comprising 8 Raspberry Pi cards, which can be fitted in a handbag. Despite its size, it demonstrates a real supercomputer, such as Salomon or Anselm, in terms of design, and it allows parallel computations via Ethernet connection and MPI library. Raspberry Pi card is in the size of a credit card, but its CPU has 700 MHz and its operational memory is 512 MB. As a cluster, Permoník has the power of 1GFLOPS. It is mainly used for promotion of supercomputing at events for students.
