📦 Required Packages

This program uses the following packages:

gopkg.in/yaml.v2

📋 Build Instructions

Considering that you already installed a recent version of Go (version 1.22.0 and higher), you can build the project using the following command:

go build -o generate

For running the program, you can use the following command:

./generate -config <path-to-config-file>

Or you can build and run the program in one step using the following command:

go run generate.go -config <path-to-config-file>

📝 Configuration Format

The configuration file is in YAML format. For more information on the configuration file, please refer to the Configuration File example.

🔧 Features

The framework is highly customizable and can be used to generate tasksets with different characteristics. In this section, we will discuss some of the features of the framework.

The framework can be used to generate task sets with the following characteristics:

Periodic tasks
Fork-join DAG tasks
Random DAG tasks

To generate the periods of the tasks, the framework uses the following distribution functions:

Uniform distribution
Log-uniform distribution
Uniform distribution with discrete values (which should be provided in the configuration file)
Log-uniform distribution with discrete values (which should be provided in the configuration file)
Automotive benchmark

Utilization of the tasks also can be generated using the following distribution functions:

UUniFast-Discard
RandFixedSum
Automotive benchmark

The task set can also be partitioned using the following partitioning algorithms:

Best-fit
Worst-fit
First-fit

The framework also can unfold a generated taskset to a jobset with a specified priority assignment algorithm. Currently, the following priority assignment algorithms are supported:

Rate Monotonic
Deadline Monotonic
Earliest Deadline First

⚠️ Note: In addition to the features already listed, this framework is designed to support parallel execution. This means that multiple tasks can be run concurrently, significantly improving the performance and efficiency of the system, especially when dealing with large task sets.

📄 Output Format

The generated task set can be saved in either CSV or YAML format. The output format can be specified in the configuration file.

🚧 Limitations

For now, the generators just support the discrete-time model and all the numbers are integers.

🔄 Previous Work

This project is a newer version of the Real-time task generator project. The previous project was written in Python and was not as efficient as the current project. The current project is written in Go and designed to be more efficient, scalable, and provide more options.
