Compi is an application development framework for portable computational pipelines. A software pipeline is a chain of processing elements so that the output of each element is the input of the next.

There are many fields where computational pipelines constitute the main architecture of applications, such as big data analysis or bioinformatics.

Many pipelines combine third party tools along with custom made processes, conforming the final pipeline. Compi is the framework helping to create the final, portable application.

• Compi source code: https://github.com/sing-group/compi

Compi is an ecosystem that comprises:

• compi: the workflow engine with a command-line user interface to control the pipeline execution.
• compi-dk: a command-line tool to help in the development and packaging of Compi-based applications.
• Compi Hub: a public repository of Compi pipelines that allows other users to discover, browse and reuse them easily.

Binaries for compi and compi-dk for Linux 64-bit systems are available here: https://www.sing-group.org/compi#downloads

Portable versions (.tar.gz) and self-extracted installers (.bsx) are available for both. compi distributions are self-contained and do not require any dependencies. compi-dk only requires Docker, which should be available for the compi-dk build command to work.

Alternatively, the compi project can be build to obtain the compi and compi-dk binaries.

To do so, just download or clone this project and run the following command (Note: requires Maven 3.x and Java 1.8): mvn clean package -PcreateInstaller

If the build succeeds, then:

• The compi and compi-dk builds will be available at compi/cli/target/dist/ and compi/dk/target/dist/, respectively. Java is required to run these binaries. The compi also requires envsubst to be available at runtime and compi-dk requires Docker, which should be available for the compi-dk build command to work.
• the compi and compi-dk Linux 64-bit builds will be available at compi/cli/target/installer/ and compi/dk/target/installer/, respectively.
