Description
The C++ reconstruction framework JANA has been written to support the
next generation of Nuclear Physics experiments at Jefferson Lab in
anticipation of the 12GeV upgrade. This includes the GlueX experiment
in the planned 4th experimental hall "Hall-D". The JANA framework was designed to allow
multi-threaded event processing with a minimal impact on developers of
reconstruction software. As we enter the multi-core era, thread-enabled code will become essential to utilizing
the full processor power available without invoking the logistical overhead
of managing many individual processes. Event-based reconstruction lends
itself naturally to mutli-threaded processing. Emphasis will be placed on the
multi-threading features of the framework. Test results of the scaling
of event processing rates with number of threads will be shown.
Summary
