Furthermore with ICI the GigaBooster also supports z-buffer communication. The GigaBooster is the first commercial supercomputer that exploits this efficient communication concept. Programming the GigaBooster Communication Standards MPI MPI is a new library specification for message-passing, proposed as a standard by a broadly based committee of vendors, implementors, and users. Additionally there is also a socket based implementation available. ICI ICI was designed for data-parallel programming.
All nodes run the same program but calculate different parts of the data.
At the start of the program, each node receives a part of the data. It performs the calculation on its part. The data is sent to the communication network after the calculation. The network distributes it to the other nodes. As soon as the nodes have received the new input data, a next calculation step begins.
