Simulator development is already a huge burden for many academic and
industry research groups; future complex or heterogeneous multi-cores,
as well as the multiplicity of performance metrics and required
functionality, will make matters worse. We present a new simulation
environment, called UNISIM, which is designed to rationalize simulator
development by making it possible and efficient to distribute the
overall effort over multiple research groups, even without direct
cooperation. UNISIM achieves this goal with a combination of modular
software development, distributed communication protocols, multi-level
abstract modeling, interoperability capabilities, a set of simulator
services APIs, and an open library/repository for providing a
consistent set of simulator modules.
