simpy.sourceforge.netSimPy is an extensible object-oriented discrete event simulation package for Python 2.2 and later. It uses generators for efficient implementation of coroutines. It has a GUI and a plotting package. Tutorial, manuals and many examples are included.
Release 1.5 is a new production version of SimPy. It adds advanced synchronization capabilities through additional 'yield' commands. SimPy 1.5 runs SimPy 1.4.2. scripts unchanged.
Changes ========= SimulationRT --------------------------------------- Python on a Win32 OS provides *time.clock*, a high resolution clock which can be used to measure real time. The nearest facility to this on Linux and Unix is *time.time*. SimulationRT now automatically selects the right clock, depending on the OS the SimPy script is run on.
Additions ============ Advanced synchronization facilities ----------------------------------------- To support the clean, easy implementation of an even wider spectrum of simulation models, SimPy 1.5 now introduces two additional process synchronization facilities:
* SimEvents and signaling synchronization constructs,
with 'yield waitevent' and 'yield queueevent' commands. * A general "wait until" synchronization construct, with
the 'yield waituntil' command.Bugs repaired ------------- The 1.5 alpha review process identified a bug in the new SimEvents class (thanks, Sidney!). It manifested itself when a process waited or queued for one of a group of signals. This release cures that bug.
Enjoy, but don't forget to share your experiences with the SimPy community!
