A library environment for distributed memory multiprocessors

Abstract

The authors propose the design of a library environment, called PARUL (PARallel User Library), for distributed memory multiprocessor systems. An important feature of the environment is that it allows the data distributed for use of a library function as well as the results generated by the function to be retained in the network of processors to be used by subsequent library functions. The user of the library is given full control over the set of variables that are retained in the network. The authors describe the implementation details of PARUL on a multi-transputer system (PARAM) and discuss its performance.<>
