Solution Overview
Problem
Configuring and managing hybrid cluster deployments combining Kubernetes and Slurm for high-performance computing and Big Data jobs is a difficult and time-consuming process, as users typically require customized configurations that leverage features from both systems, which are not easily integrated.
Innovation Solution
An automated method is provided to create hybrid cluster deployments by combining Kubernetes with Slurm, utilizing a secure connection to enable interactive access to headless cluster managers, allowing seamless interaction between frameworks with and without software-defined networking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Kubernetes and Slurm are combined to create hybrid cluster deployments, then functionality and versatility are improved, but configuration complexity and time consumption increase
Solution Approach 1:
The patent introduces an intermediary component that bridges Kubernetes and Slurm frameworks, enabling them to work together without direct complex integration. This mediator handles the coordination and communication between the two systems, simplifying the configuration process while maintaining enhanced functionality.
Solution Approach 2:
The hybrid cluster deployment system is designed to provide universal functionality by combining the strengths of both Kubernetes (container orchestration, software-defined networking) and Slurm (job scheduling, HPC workloads) into a single multi-functional platform that can handle diverse computational tasks.
2Adaptability or versatility
If Kubernetes and Slurm are combined to create hybrid cluster deployments, then functionality and versatility are improved, but the configuration process becomes time-consuming
Solution Approach 1:
The system performs preliminary configuration actions by pre-establishing integration templates, default settings, and automated provisioning scripts for hybrid cluster deployments. This allows the complex Kubernetes-Slurm integration to be configured quickly by leveraging pre-prepared configurations rather than building from scratch.
Solution Approach 2:
The hybrid cluster deployment system incorporates self-service capabilities through automated configuration tools that can autonomously set up and optimize the integration between Kubernetes and Slurm based on detected requirements and best practices, reducing manual configuration time.
3Ease of operation
If a secure connection is created from Kubernetes to Slurm node, then interactive access is enabled, but network complexity increases
Solution Approach 1:
A network intermediary or gateway is introduced to manage the secure connection between Kubernetes and Slurm. This intermediary handles authentication, encryption, and connection management, enabling interactive access while abstracting the network complexity from users and applications.
