Resource centre Pecs SC
Pecs supercomputer is a SGI 1000 Ultraviolet with SMP (ccNUMA) architecture. The machine has Intel Xeon X7542 (Nehalem EX) type 6-core processors and the total cores are 1152. The computing power exceeds the value of 10 Tflops. Each processor can directly access the 6 terabytes of memory over the Numalink communication infrastructure. This supercomputer has 0.5 petabyte storage, and high-end visualization subsystem is added which is an efficient, modern, water-cooled technology. It has SUSE Linux Enterprise operating system.
