Streamix RTS smxrts

The runtime system (RTS) library for the coordination language Streamix. This library is used by any Streamix box which together with this runtime system may form a Streamix application.

In short, the runtime system spawns box instances as threads and manages the communication amongst the box instances.

Installation

The release page offers pre-compiled debian packages which can be installed through command line.

Note that time-triggered nets are executed with RT-Tasks. In order for this to work, the user executing the Streamix application requires the appropriate rights. These can be configured in /etc/security/limits.conf. E.g. add the line localtest - rtprio 99 in order to allow the user localtest to run Streamix applications with RT priority.

Building

To build the RTS from scratch run the following commands:

make
sudo make install

Dependencies

• smx-dep-zlog This library wraps the publicly available zlog library in order to facilitate installing processes. Note that the zlog library was altered slighly to accommodate for a potential priority-inversion problem when using RT threads.

• libbson

  sudo apt install libbson-dev
  

• pthread

  sudo apt install libpthread-stubs0-dev
  

• lttng

  sudo apt-get install lttng-tools
  sudo apt-get install lttng-modules-dkms
