Parallel Communication in a Large Distributed Environment
M. Satyanarayanan and Ellen H. Siegel
In this paper we describe the evolution of MultiRPC, a parallel
remote procedure call mechanism implemented in Unix. Parallelism is obtained
from the concurrency of processing on servers and from the overlapping
of retransmissions and timeouts. Each of the parallel calls retains the
semantics and functionality of our standard remote procedure calls. The
underlying communication medium need not support multicast or broadcast
transmissions. We derive an analytic model of the system and validate it.
Our experimental observations demonstrate the feasibility of using MultiRPC
to contact up to 100 servers in parallel.
