PARALLEL PRocEssoRs AND

This paper describes the adaptation of a finite element program with explicit time integration to a massively parallel SIMD computer, the CONNECTION Machine. The adaptation required the development of a new algorithm, called the exchange algorithm, in which all nodal variables are allocated to the element with an exchange of nodal forces at each time step. The architectural and C* programming l...

Scalable Scheduling in Parallel Processors

A study of scalable data intensive scheduling involving load distribution on multi-level fat tree networks is presented. It is shown that the speedup of processing divisible loads concurrently on a homogeneous single level tree increases linearly as the number of processors is increased. This behavior is markedly different from that of past research on sequential scheduling where speedup satura...

Watchdog processors in parallel systems

A watchdog processor (WDP) is a relatively simple coprocessor built for concurrent, information compaction based error detection in the main program control flow.A new algorithm called SEIS (Signature Encoded Instruction Stream) is presented for assigning signatures to high levelinstructions. The main idea of this method is to embed the information necessary to the program flow check into the s...

Particle Tracking Using Parallel Processors

During the past decade massively parallel processors (MPPs) have slowly gained acceptancewithin the scientiic community. At present these machines typically contain a few hundred to one thousand oo-the-shelf microprocessors and a total memory of up to 32 GBytes. The potential performance of these machines is illustrated by the fact that a month long job on a high end workstation might require o...
