SMB Supercomputing: IBM BladeCenter QS22 Launches Green IT List


With the green supercomputer "Monte Capanne" from the German IBM development center in Böblingen, based on the open Linux operating system, it has been possible to achieve a 35 percent better performance compared to the previous leading system of the Green500 list. The supercomputing installation consists of 84 commercially available IBM BladeCenter QS22s connected via an Infiniband network. These blade systems are also at the heart of the world's most powerful supercomputer, the "Roadrunner" at the Los Alamos American research center, which tops the traditional Top500 list of the world's most powerful computers with a capacity of one quadrillion arithmetic operations per second.

According to the manufacturer, an IBM BladeCenter QS22 costs less than € 7000 and is therefore of particular interest to medium-sized companies that want to use energy-efficient, expandable and extremely powerful computers, for example in design and simulation, in the multimedia sector or in medical data processing. The basic technology of the blade server is the "IBM PowerXCell 8i" processor, a further development of the Cell / BE processor developed by Sony, Toshiba and IBM for the Playstation 3. Game processors today are often more powerful than standard processors and would therefore offer optimal for supercomputing. As the manufacturer explains, the Cell / BE architecture with its nine processor cores is not only extremely powerful, but consists of just 250 million transistors. Other comparable processors would now use more than a billion transistors, resulting in higher power consumption. Thus, the architecture of the Blade system from IBM works extremely efficiently and, according to the Green500 list, makes it the most energy-efficient system on the market today.
