Most powerful supercomputer from IBM

IBM will build two supercomputers for the American Department of Energy (DOE) that will overshadow everything. For over a quarter of a billion dollars, the DOE gets a computer with a total of 460 tera-flops (460 trillion floating-point operations per second) computing power.

That is 1.5 times the computing power of the 500 fastest supercomputers combined! One can imagine that a huge number of processors are required for this enormous performance. 12,544 Power-5 processors work in one of the computers, 64 of which are combined to form an eServer node. 196 of these eServers are connected to one another via a special high-speed connection, which should have a total bandwidth of 12.5 TByte/s. Of course, a huge main memory must also be available. IBM's new supercomputers can access an unimaginable 50 Tbytes of main memory with a total memory bandwidth of 156 Tbytes/s.

As is so often the case, the military can enjoy such concentrated computing power. Mainly for the simulation of weapon systems. For example atomic bomb explosions should be able to be represented completely in 3D. Unfortunately, it has not yet been announced when the computers will go into operation.
