MUSCLE tutorials

There are some examples provided within the MUSCLE bundle. Example code for kernels can be found in the directories src/java/examples and src/cpp/examples. There are also prepared configurations for coupled examples CxA (MUSCLE simulations), which can be found in the src/cxa directory.

Running SimpleExample

Sender

In src/java/examples/simplejava/Sender.java we provide a minimalist kernel written in Java, which sends data (an array of double).

Receiver

In src/java/examples/simplejava/ConsoleWriter.java we provide a simple kernel written in Java. It receives data (an array of double) and prints its content to the standard output.

CxA (coupling schema)

The configuration src/cxa/SimpleExample.cxa.rb configures a minimal CxA which couples the examples.simplejava.Sender and examples.simplejava.ConsoleWriter kernels.

Execution

To run the simulation defined in src/cxa/SimpleExample.cxa.rb use the following command:

muscle2 --cxa src/cxa/SimpleExample.cxa.rb --main --allkernels

or in shorthand notation

muscle2 -c src/cxa/SimpleExample.cxa.rb -am

It will first start the Simulation Manager, of which one per simulation is necessary, and then the local manager, which manages the kernels that are started with one muscle2 invocation.
