What Are NVIDIA NGC Containers & How to Get Started Using Them | by James Montantes | Nov, 2021
Modern science- and enterprise-driven Artificial intelligence (AI) and Machine Learning (ML) workflows aren’t easy to execute given the complexities arising from a number of packages and frameworks typically utilized in any such typical job. All the mutual dependencies and interrelationships between these open-source frameworks could make the lifetime of an information scientist fairly depressing.
One universally highly effective, but deceptively easy strategy to clear up this drawback is the usage of containers. A container is a conveyable unit of software program that mixes the appliance and all its dependencies right into a single package deal that’s agnostic to the underlying host OS. Thereby, it removes the necessity to construct complicated environments and simplifies the method of utility improvement to deployment.
Docker and Kubernetes (container administration) are two open-source applied sciences that come to thoughts instantly on this facet.
However, constructing GPU-optimized containers, tuned particularly for probably the most demanding deep studying purposes, isn’t a trivial job. To clear up this concern, NVIDIA, the pioneer within the GPU applied sciences and deep studying revolution, has provide you with a wonderful catalog of specialised containers that they name NGC Collections.
In this article, we explore their basic usage and some variations.
There are many use cases and scenarios where these containers can be applied to. Data scientists and hardcore ML engineers can both use them for various purposes. Some of the key features of this NGC catalog are:
- They represent a truly diverse set of containers spanning a multitude of use cases
- They encompass all the popular built-in libraries and dependencies for easy compiling of custom applications as practiced in typical data science and ML domain
- They are extremely portable, allowing a data scientist to develop her applications on the cloud, on-premises, or at the edge
- They realize reduced time-to-solution by scaling up from single-node to multi-node systems in an intuitive manner
Professional data scientists and even hobbyists can use these features to their full advantage. But NGCs are more than that. They are also built with large enterprises in mind.
- They are enterprise-ready and scanned for common vulnerabilities and exposures (CVEs).
- They are backed by optional enterprise support to troubleshoot issues for NVIDIA-built software
As mentioned above, the NGC containers and catalog covers a wide variety of use cases and application scenarios. For example, they feature both popular deep learning frameworks and High-performance Computing (HPC) libraries and toolkits that also leverage the accelerated computing of GPU clusters. The following figure illustrates this universe,

Almost all data scientists are familiar with deep learning frameworks like TensorFlow and PyTorch, but containerized HPC is a specialized domain that deserves special mention and some elaboration. Here are some brief facts about these containers.
NAMD is a parallel molecular dynamics code designed for high-performance simulation of huge biomolecular programs. It makes use of the favored molecular graphics program VMD for simulation setup and trajectory evaluation however can be file-compatible with AMBER, CHARMM, and X-PLOR. It works properly with Pascal(sm60), Volta(sm70), or Ampere (sm80) NVIDIA GPU(s).
GROMACS is a molecular dynamics utility designed to simulate Newtonian equations of movement for programs with a whole bunch to hundreds of thousands of particles. This package deal is designed to simulate biochemical molecules like proteins, lipids, and nucleic acids which have loads of sophisticated bonded interactions.
GROMACS performs properly with the next GPU household — Ampere A100, Volta V100, or Pascal P100 GPUs. A excessive clock charge is extra vital than absolutely the variety of cores, though having multiple thread per rank is desired. GROMACS will help multi-GPUs in a single system however wants a number of CPU cores for every GPU.
It is finest to begin with one GPU utilizing all of the CPU cores after which scale as much as discover what performs finest for the particular utility case.
REgularized LIkelihood OptimizatioN implements an empirical Bayesian method for the evaluation of electron cryo-microscopy (Cryo-EM). Specifically, RELION supplies refinement strategies of singular or a number of 3D reconstructions in addition to 2D class averages.
It is comprised of a number of steps that cowl the whole single-particle evaluation workflow — beam-induced movement correction, CTF estimation, automated particle choosing, particle extraction, 2D class averaging, 3D classification, and high-resolution refinement in 3D. RELION can even course of motion pictures generated from direct-electron detectors, apply ultimate map sharpening, and carry out the local-resolution estimation. It is an extremely vital device for finding out dwelling cell mechanisms.
RELION, like the opposite HPCs, works properly with Pascal(sm60), Volta(sm70), or Ampere (sm80) NVIDIA GPU(s). The NGC container is constructed to benefit from these GPU programs. Large native scratch disk house, ideally SSD or RamFS is required. A excessive clock charge is extra vital than the variety of cores.

Before an information scientist can run an NGC deep studying framework container, they must make it possible for their localized Docker surroundings helps NVIDIA GPUs.
The detailed information will be discovered right here on the NVIDIA web site: Running a container.
Essentially, the core parts of the workflow include,
- Enabling the GPU help on docker
- Specifying a person
- Setting flags
- Remove flag
- Interactive flag
- Volumes flag
- Mapping ports flag
- Shared reminiscence flag
- Restricting publicity of GPUs flag
- Managing container lifetime
The stream is visualized beneath.
