The office (for Giga Cube or Grand Challenge) a parallel computer of the German company Parsytec is and at the beginning of the 90's was manufactured.

As processor transputers became T-805 (30 MHz) of the company Inmoseingesetzt. The arithmetic performance of a processor amounted to 4.4 MFLOPS.Jedem processor stood for 1 MByte local main storage to of the manufacturer announced version office with InmosT-9000-Transputern could be never realized, since that was not published.

The network architecture was a two-dimensional lattice. Those communication-speed-lay with 20 MBit/s.

For the time the modular concept of the GCs was unusual. A module contained four cluster with in each case 16 transputers and one-own current supply, I/O and communication connection by combination of modules could theoretical to to 16384 processors to a very efficient be interconnected system with one another. The designation Office-x indicates those size of the system. A GC-1 possesses 64 processors, einGC-2 256, a GC-3 1024, a GC-4 4096 and einGC-5 16384 processors. While the smaller versions to zumGC-3 were air-cooled, should be water cooling-used for the larger.

As operating system PARIX was used.

The power input of a system with 1024 processors was with approx. 27kW, the weight with nearly a ton. The purchase price betrug1992 approx. 1.5 million DM.

The two largest installations office had 1024 processors (16Module with in each case 64 transputers) and at computing centres that universities Cologne and Paderborn were operated. The PaderbornerExemplar office is since October 1994 in the PaderbornerComputermuseum to visit (no longer ready for operation).

The office with 1024 processors 1992 reached a placement in derTOP500-Liste that world-wide fast supercomputer installations. Germany far it reached place 22der fastest computer.
