GF11

GF11 is a parallel processor currently under construction at the IBM Yorktown Research Center. The machine incorporates 576 floating-point boards. Each board has space for 2 × 106 bytes of memory and is capable of 2 × 107 floating point operations per second, given the total machine a peak of 1.15 × 109 bytes of memory and 1.15× 1010 floating point operations per second. The floating-point processors are interconnected by a dynamically reconfigurable switching network. At each machine cycle any of 1024 preselected permutations of data can be realized among the processors. The main intended application of GF11 is a class of calculations arising from quantum chormodynamics. © 1986 Plenum Publishing Corporation.
