fileserver. The Edinburgh Concurrent Supercomputer Project (ECSP) was formed to manage and support the facility, which was commissioned at the end of 1987. Over the next few years, the system received several upgrades, including more transputers (reaching, at its peak, around 400 processors) and the installation of M²VCS and MeikOS system software, which enabled

access and removed the need for the MicroVAX. In 1990, the Edinburgh Concurrent Supercomputer Project was succeeded by the Edinburgh Parallel Computing Centre, which consolidated the project with other parallel computing resources and activities within the University. The ECS continued to be used for a variety of academic and commercial research work. In October 1992 the ECS was reconfigured as a
