The pace of development of modern computing systems shocking imagination - productivity, which possess the most powerful computers to scientific calculations and research only a decade ago, is now available to a normal user. Of course, growing opportunities not only computers but also their productivity needs, because over time the amount of data for processing only increases - this concerns not only research but also commercial projects. Thus, the demand for powerful systems has not decreased, which, by law, market development, brings the proposal. The company Cray, which specializes in assembling powerful computing systems, offers customers a personal supercomputer Cray CX-1. Of course, you can call it personal with some natyazhkoy, because based developers have a platform Intel Xeon:up to sixteen server processor Xeon, as a dual-or quad, significant amounts of RAM and disk space. The main advantage model Cray CX-1 is the possibility of a flexible system configuration - into a single body may establish from one to eight bleyd servers, each equipped with two processors Intel Xeon, up to 64 GB of memory, as well as high performance graphic adapter family of NVIDIA Quadro. Disk subsystem can be represented by eight 2, 5 - inch hard drive with an interface SAS/SATA, with the possibility of combining devices in arrays of RAID-0, 1, 5, 6, 1 0, 5 0 - enough and performance for virtually any task . Moreover, the user can work together to organize three systems Cray CX-1 through external InfiniBand switches and Gigabit. Another advantage is the relative compactness of systems and low power consumption - the size of one block form the 31 x 45 x 90 cm, while the weight of 28, 3 kg (maximum weight - 62 kg), a standard used to supply 1 , 6 kW power supplies. But most importantly, that the performance of Cray CX-1 is very high, and computers can rightfully be Supercomputing title - if such devices were issued in 2004, they would be included in the list of five most powerful computer systems in the world Top500 . But do not forget that a similar performance at that time possessed huge computer centers, consuming enormous amounts of energy, and equipped with a powerful cooling systems, rather shumyaschimi. That is, for some four years, supercomputers have gone from huge and expensive designs to a rather compact systems, a purchase that can afford even a small IT-company - at cost Cray CX-1 is $ 12, 5 thousand (upper limit of approximately $ 50 thousand). Naposledok note that personal supercomputer running the operating system Windows HPC Server 2008 or Red Hat Linux Enterprise, ensuring ease of configuration and daily work.
