The Mesa architecture is implemented on a variety of processors, and dynamic instruction frequency data for two programs is used to analyze the architecture in an implementation independent fashion.

WFS is a shared file server available to a large network community. WFS responds to a carefully limited repertoire of commands that client programs transmit over the network. The system does not utilize connections, but instead behaves like a remote disk and reacts to page-level requests. The design emphasizes reliance upon client programs to implement the traditional facilities (stream IO, a directory system, etc.) of a file system. The use of atomic commands and connectionless protocols nearly eliminates the need for WFS to maintain transitory state information from request to request. Various uses of the system are discussed and extensions are proposed to provide security and protection without violating the design principles.

Metric is a distributed software measurement system that communicates measurement data over the PARC computer network, the Ethernet. Metric is used to instrument stand alone and distributed computer systems (it works in an environment of about 90 machines total and is used by about 15 machines).
