CD++ - Extended States

An extended and improved version of CD++ for Cell-DEVS.

Getting Started

Download

The easiest way to get the source code is by cloning the git repository:

 $ git clone https://github.com/SimulationEverywhere/CDPP_ExtendedStates-codename-Santi.git 

Prerequisites

• GCC 4.7 or higher (with C++11 support)
• bison
• GNU make

Compilation

In order to compile the simulator kernel, go to the directory where its source code is located and run make. For example,

 $ cd cdpp/src
 $ make

Upon finishing, the bin subdirectory will contain the executable file cd++. A static library containing core functionality of the simulator is also provided by default.

Examples

Simulation of a Cell-DEVS model

If you wish to simulate the model described by, say, file model.ma, execute:

 $ bin/cd++ -mmodel.ma

Simulation of an ad-hoc atomic model

For this we suggest to use as baseline the pulse example included in the project (see examples/pulse/src). In particular, it is important to include a Makefile defining, at least,

• The KERNEL_SRC variable pointing to the directory where the cd++ source code is located.
• The MODEL_FLAGS variable with value -DREGISTER_ATOMICS. This is to compile the code responsible for registering the desired atomic model into the simulator kernel.
• The inclusion of definitions and compilation rules provided by the simulator:

  include $(KERNEL_SRC)/Makefile.rules
  include $(KERNEL_SRC)/Makefile.defs

It is also important to include an implementation of the function

void register_atomics_on(ParallelModelAdmin &admin)

whose purpose is to register into the kernel the atomic models that the user wants to use. In general, it is sufficient to include a line like the following:

admin.registerAtomic(NewAtomicFunction<ModelClass>(), "Model name");

Please see the aforementioned example included in the source code for further details.
