(※1) Enroot: A lightweight, rootless container runtime developed and provided by NVIDIA. Designed with HPC environments in mind, it supports OCI-compatible container images.
(※2) Pyxis: A SPANK (Slurm Plug-in Architecture for Node and job Kontrol) plugin for Slurm, provided by NVIDIA. It enables direct invocation of "Enroot" containers from Slurm job submission commands, simplifying container execution on HPC clusters.

[Background]
As research and development in generative AI and large language models (LLMs) advances rapidly, ensuring the portability and reproducibility of workloads through container technology has become essential in the HPC (High-Performance Computing) domain. The "GMO GPU Cloud" Managed HPC Cluster Service has offered "Singularity," a container runtime widely adopted in HPC environments, since its launch.
At the same time, demand has grown for capabilities such as the ability to launch containers natively from Slurm job submission commands and to run workloads that conform directly to NVIDIA's software stack. In response to these needs, GMO Internet has added support for "Enroot," a lightweight container runtime for HPC developed and provided by NVIDIA, and "Pyxis," a SPANK (※4) SPANK (Slurm Plug-in Architecture for Node and job Kontrol): A plug-in architecture for extending Slurm's job execution framework.
[Key Benefits and Features]
• Choice of container runtime best suited to each workload, from "Singularity" to "Pyxis/Enroot"
• Direct submission of Docker/OCI (Open Container Initiative)-compatible container images to Slurm jobs via "Pyxis"
• Improved reproducibility and portability of research and development environments, enabling smooth migration from local to cluster environments
• Flexible container operations that leverage existing job script assets
With this update, the "GMO GPU Cloud" Managed HPC Cluster Service provides a flexible foundation that allows users to select the container runtime best suited to their workload characteristics and existing development environments. Improved environment reproducibility and portability reduce the cost of migrating from local setups to production clusters, contributing to faster development and research cycles.
[Future Outlook]
As AI becomes the foundation of society and industry, building high-performance GPU infrastructure within Japan has emerged as a critical factor in the country's AI competitiveness. GMO Internet will continue to advance the "GMO GPU Cloud" Managed HPC Cluster Service, providing a robust development and research infrastructure for AI, machine learning, and HPC. As an indispensable domestic infrastructure for Japan's AI industry, GMO Internet remains committed to driving innovation across society and industry.
