   Can be installed with this installation guide.
   The command will be ./gradlew wrapper --gradle-version=7.6 --distribution-type=bin.
   Installation can be verified with ./gradlew --version.
2. JDK 11+
   Can be installed with this installation guide.
   Installation can be verified with java --version.

Build and install dependencies using:

./gradlew build clean

NB! Every launcher needs RabbitMQ 3.11 up and running on current host (localhost) on default ports (5672, 15672).

To run RabbitMQ, the following command can be used:

docker run -it --rm --name Rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3.11-management

In that case the following command can be used to check if RabbitMQ is available:

docker exec Rabbitmq rabbitmq-diagnostics -q check_running

Configuration files:
Each launcher can accept two parameters or zero parameters (in that case the defaults will be used).
First parameter is a configuration file (without file extension) (physical first, virtual second).
These files should reside in src/main/resources directories.
Files should contain physical and virtual configuration matrixes in .CSV format, where connected nodes are represented by 1 and not connected by -1.

Simple launcher runs all the nodes in a single thread:

./gradlew -P MAIN_CLASS=ds.launchers.SimpleLauncher run [--args="PHYSICAL_CONFIG VIRTUAL_CONFIG"]

Process launcher runs all the nodes in different native processes (fork / join):

./gradlew -P MAIN_CLASS=ds.launchers.ProcessLauncher run [--args="PHYSICAL_CONFIG VIRTUAL_CONFIG"]

Individual launcher runs a single node (gets its' id from PHYSICAL_ID environmental variable).
Can be used to run system on separate processes / machines / hosts / containers:

./gradlew -P MAIN_CLASS=ds.launchers.IndividualLauncher run [--args="PHYSICAL_CONFIG VIRTUAL_CONFIG"]

Run whole system using default configurations in separate Docker containers:

bash docker/run_containers.sh
