Abstract

This paper presents the Light Communication (LiCo) library, designed to implement communications primitives based on permanent, point-to-point, bi-directional channels. LiCo, using the standard TCP layer, allows the interoperability of different computing systems. LiCo library has been designed to be as simple as possible, hiding to the programmers all the unnecessary details connected to initializations and HW heterogeneity management. We report results in the ping/pong test performed between different systems connected through different communication media and we compare, on the same ping/pong, LiCo performances with the ones achieved by PVM and by straight socket communications.
