Containers overview

You can use idmtools in containers, such as Singularity and COMPS. This can help make it easier for other data scientists to use and rerun your work without having to try and reproduce your environment and utilities. You just need to share your container for others to run on their own HPC.

“A container is a software package that contains everything the software needs to run. This includes the executable program as well as system tools, libraries, and settings”, as quoted from ( The conceptual components of containers are the same regardless of the specific container technology, such as Singularity and Docker.

Containers and science

Containers and science are great partners. The primary reason being the enhancement of reproducibility in scientific computing. Another reason is to allow access to more utilities beyond the scope of what is available by default within your HPC environments. For example, if you need to use the Julia programming language or any other utilities not currently available in your HPC then you could create your own container with the desired utilities. This allows you control over the environment and tools in the container to be run on your HPC.

Understand Singularity

“Singularity is a free, cross-platform and open-source computer program that performs operating-system-level virtualization also known as containerization. One of the main uses of Singularity is to bring containers and reproducibility to scientific computing and the high-performance computing world.”, as quoted from
