The purpose of this paper is to supply a summary of
library subroutines and functions for parallel MIMD
computers. The subroutines have been developed and
continously extended at the University of Chemnitz
since the end of the eighties. In detail, they are
concerned with vector operations, inter-processor
communication and simple graphic output to
workstations. One of the most valuable features is
the machine-independence of the communication
subroutines proposed in this paper for a hypercube
topology of the parallel processors (excepting a
kernel of only two primitive system-dependend
operations). They were implemented and tested for
different hardware and operating systems including
PARIX for transputers and PowerPC, nCube, PVM, MPI.
The vector subroutines are optimized by the use
of C language and unrolled loops (BLAS1-like).
Hardware-optimized BLAS1 routines may be
integrated. The paper includes hints for
programmers how to use the libraries with both
Fortran and C programs.
