Fortnet (3L) vl.0: Implementation and extensions of a message- passing harness for transputers using 3L parallel Fortran

Abstract In previous work an occam-2 harness was developed which allowed parallel Fortran programs on a multicomputer to communicate using a simple message-passing subroutine library on a Meiko Computing Surface. The present work extends this harness to transputer arrays supporting the 3L Parallel Fortran, and further considers processor access of a shared filestore, and improvements to efficiency of communication. Destination buffering and direct access to the lowest-level 3L channels is found to be ... Title of program: FORTNET (3L) V1.0 Catalogue Id: ACHQ_v1_0 Nature of problem Parallel computers, such as transputer networks, with a high performance/cost ratio, are attractive for large scale computational tasks, such as Computational Fluid Dynamics. The large investment in sequential Fortran-77 code, in all branches of Science and Engineering, forces us to find an efficient means for porting existing codes to multiprocessors. Tools are limited: the Parallel Fortran v2.0 programming system for transputer networks has language extensions to facilitate message passing bet ...
