The Computing and Communications Division at the Los Alamos National Laboratory has designed and is building a parallel microprocessor system (PuPS) to serve as a research tool for evaluating parallel processing of large-scale scientific codes. PuPS is an experimental architecture consisting of an orthogonal array of 20 processing elements by 32 memory elements, establishing a tightly coupled, shared-memory (16-Mbyte) machine. The hardware incorporates VLSI components, such as 16-bit microprocessors, floating-point co-processors, and dynamic random access memories. The design replaces conventional MSI/SSI circuitry with programmable array logic, logic sequencers, and logic arrays. This experimental system, which is only 1 element of the parallel processing research being done by the Laboratory's Computing and Communications Division, will enable direct comparisons of speedups of algorithms for a variety of multiprocessor architectures.

Monthly reports documenting San Antonio municipal board activities and city permitting for April 1984.

The magnitude of vibrations of the Linac structure due to on site disturbances, such as cooling towers, pumps, generators, Highway 280 overpass traffic, is of interest. CN-263, for example, discusses tolerances of random (i.e., uncorrelated) quad jitter and suggests that amplitudes should not exceed 0.7 microns rms. This note describes the results of a series of measurements carried out in the summer of 1983. In general, the tolerance is not exceeded, but there appears not to be a good safety factor at low frequencies.
