The Ptolemy environment has inherent features that make it an attractive
base for building parallel systems and simulations, such as its dataflow
scheduling and partitioning. Of particular interest for parallelism
in Ptolemy are the matters of inter-process communication, program
scheduling, and synthesis of software from dataflow graphs. In order to
create and test parallel systems and simulations, an appropriate computing
platform is needed. Existing parallel platforms for Ptolemy include
standard TCP/IP connected workstations and the Berkeley Network of
Workstations (NOW).
This research focuses on implementing parallel systems and simulations
in Ptolemy. Current research includes the use of fast active messages
(Lanai AM) on the NOW in the Ptolemy Code Generation in C (CGC) domain, as
well as support in Ptolemy for Split-C (parallel version of C) on the NOW.
Future work will include other parallel architectures, such as parallel
embedded systems.
