This page is designed as the central navigation source for those within the ATLAS Level 2 trigger simulation group who are specifically working with Ptolemy.
This page is a collection of work in progress and is not intended to be taken as final "published" work.
A portion of the ATLAS trigger simulation group is attempting to exploit the Ptolemy simulation package to simulate parts of the ongoing trigger work. At present the effort is concentrated upon simulation of the "Pilot Project Ethernet Tesbed programme".
The group is attempting to keep the simulation very simple (and factorised), so that:
A more detailed explanation of these ideas is given in Overview which is a pdf document with some examples.
At the heart of the thinking of many of those involved is that a simulation of the full ATLAS data flow system should be possible at a very high level, where the responses of nodes is determined by simple transfer functions. More about this idea can be read in some Slides presented at the Chamonix workshop
The full set of design documents are still available from the group's old page but, to avoid misleading newcommers, only the ones that are still relevant are listed here.
Most of these documents are derived from the Ptolemy code itself, so are kept reasonably up to date.
Still draft unless otherwise stated.
Watch this space!
Regular snapshots of the latest "working" source code can be found in the distribution directory.
The main ATLAS Level 2 simulation page is the ATLAS Dataflow modeling page at NIKHEF.
