An Appreciation of the Subtleties of Shared Channels in occam3

Waithe, S.W.; Kerridge, J.M.

Abstract

By exploiting virtual channels implemented on the INMOS T9000 transputer, occam3 offers the facility of sharing. This allows us to declare a channel as SHARED which then allows an arbitrary number of processes to communicate across this channel. By means of an occam2 implementation of this feature, we uncover the subtleties of the occam3 implementation, the manner of use, the necessary implementation decisions, and the role of virtual control blocks.
