✦ Synopsis

HEP memory management packages such as YBOS and ZEBRA have been implemented and are currently running on a variety of mainframe computers. These packages were originally designed to run on single CPU engines. Implementation of these packages on parallel machines, with loosely or tightly coupled architectures, is discussed. ZEBRA (CERN package) on ACP (Fermilab) is presented in detail. The design of memory management systems for the new generation of ACP systems or similar parallel architectures is presented. The future of packages such as ZEBRA is not only linked to system architecture, but also to languages issues. We briefly mention penalties in using F77 with respect to other increasingly popular languages in HEP, such as C, on parallel systems.

The paper discusses issues pertinent to performance analysis of massively parallel systems. A model of parallel execution based on threads of control and events is then introduced. The key ingredient of this model is a measure of the communication complexity, which gives the number of events \(E\) a
