Workshop on Token Based Computing (ToBaCo)

Bologna, Italy

June 22, 2004

This workshop will take place within the 25th International Conference on Applications and Theory of Petri Nets (ICATPN'04)

Concurrency in inherently related to distributed control. The abstract models of many concurrent systems consist of graphs that represent the underlying structure and tokens that mimic the dynamic behaviour. Petri nets, Kahn process networks, Boolean dataflow networks, cellular automata, etc, are some popular examples. The current technological trends have also had a tangible impact in the computational models and real-life applications: global computing, mobile computing, globally-asynchronous locally-synchronous systems, nano and quantum computing. This workshop is an attempt to gather researchers from different areas of Computer Science and Engineering that use Token Based Computing models in their systems.

Token-based computing on nanometer scales


Abstract:
While the ongoing development of nanotechnology is expected to lead to extremely powerful computers,
it is likely to require new computer designs. This talk focusses on designs employing signals in the form
of tokens that are passed around asynchronously. Not needing a central clock, such designs promise
decreased heat dissipation, which is especially advantageous at high integration densities. Examples given
include cascades of interacting elements, which behave like rows of domino stones toppling each other, and
asynchronous cellular automata implementing such cascades. Cellular automata have attracted increasing
attention for implementations by nanotechnology because of their regularity, which facilitates assembly by
chemical synthesis in a self-organized way.
