%X The paper discusses a novel and efficient scheme for the
detection of global convergence in parallel iterative
algorithms. Convergence information is maintained as
processes which execute concurrently with computations of
the algorithm and exploit the asynchrony inherent in the
progress of most executions of such algorithms towards
global convergence. The scheme treats messages signalling
convergence as having a lower priority as compared to those
signalling non\-convergence. It minimizes the waiting time
at the end of iterations for convergence related
communications. Analytical results indicate that the global
convergence detection scheme proposed in this paper is
faster than the methods proposed earlier [3]. The scheme is
particularly suited for implementation on Transputer based
parallel machines. An OCCAM implementation of the scheme on
a torus of Transputers is described together with a method
for experimental verification of the analytical results.
