Charliecloud

Introduction to Charliecloud

Charliecloud is a lightweight and secure container solution designed for high-performance computing (HPC) environments. It enables users to build and run containers in user space without requiring root privileges, ensuring security and compatibility with multi-user systems. Charliecloud is particularly useful for scientific workflows, allowing researchers to package their applications and dependencies into portable containers that can run efficiently on HPC systems.

Charliecloud focuses on simplicity and performance, making it an excellent choice for users who need a minimalistic container solution. It integrates seamlessly with existing HPC schedulers and file systems, providing a straightforward way to manage containerized workflows.
