Computermuseum: Systemen met meerdere processoren

Systems with several processors

Sequent

De Sequent S27 was a multiprocessor system based on the Intel 80386 processor, with Dynix OS. Dynix was based on the BSD system.

The Sequent was used to develop a garbage collector for the OR-parallel Prolog system Aurora and for the implementation of ParAKL.

When no multiprocessor priitives were used the Sequent did behave as a "normal" Unix system.

Intel iPSC Hypercube

The iPSC (Intel Parallel SuperComputer) is a parallel computer with distributed memory. The system contains a number of processors, each with its own memory, interconnected by a hypercube topology. A software environment integrated within the OS permits the processors to communicate by sending messages across the network.

The department did use these machines to develop and test numerical algorithms.

Sun

Recently a number of Sun multiprocessor systems have been boiught. These use Solaris (Sunos 5.*). For the users the multiprocessor capabilities only result in more performance. Therfore we mention these systems only for completeness.
