Volcano: Cloud Native Batch System on Kubernetes
Volcano is a Cloud Native Batch System built on Kubernetes, providing a powerful and flexible platform for running high-performance workloads like AI/ML, HPC, and genomics. It extends Kubernetes to support job-centric features such as gang scheduling, fair-share scheduling, and resource management.
Project Introduction
Summary
Volcano is the first cloud-native batch system building upon Kubernetes. It aims to provide a unified platform for managing all types of compute-intensive workloads, including High-Performance Computing (HPC), Artificial Intelligence (AI), Machine Learning (ML), and data processing.
Problem Solved
Standard Kubernetes is primarily designed for long-running services. Running batch jobs, HPC tasks, and AI/ML training that require specific scheduling semantics (like gang scheduling) and efficient resource sharing can be challenging. Volcano addresses these gaps by providing a specialized scheduler and controllers optimized for these types of workloads.
Core Features
Gang Scheduling
Ensures all tasks within a job start or terminate together, preventing deadlocks and improving resource utilization for tightly coupled workloads.
Advanced Scheduling Policies
Provides advanced job queuing, prioritization, and resource fairness policies across different tenants and applications.
Heterogeneous Resource Management
Manages heterogeneous resources like GPUs and FPGAs effectively for compute-intensive tasks.
