- Other 'Ptolemy Projects' exist, including a medical one named for Ptolemy I Soter.
The Ptolemy project
is an ongoing project aimed at modeling, simulating, and designing concurrent
, embedded systems
. The focus of the Ptolemy project is on assembling concurrent components. The principal product of the project is the Ptolemy II model based design
and simulation tool. The Ptolemy project is conducted in the Center for Hybrid and Embedded Software Systems (CHESS)
in the Department of Electrical Engineering and Computer Sciences
of the University of California at Berkeley
, and is directed by Prof. Edward A. Lee
The key underlying principle in the project is the use of well-defined models of computation that govern the interaction between components. A major problem area being addressed is the use of heterogeneous mixtures of models of computation.
The project is named after Claudius Ptolemaeus, the second century Greek astronomer, mathematician, and geographer.
The Kepler Project, a community-driven collaboration among researchers at three other University of California campuses which seeks to produce an open-source scientific workflow system, is based on Ptolemy II.
