What's New

Support Dynamic Scheduling Based on Real Node Load

This feature aims to schedule pods based on real node load instead of request resource, which will optimize the node resource utilization.Currently the pod is scheduled based on the request resources and node allocatable resources other than the node usage. This leads to the unbalanced resource usage of compute nodes. Pod is scheduled to node with higher usage and lower allocation rate. This is not what users expect. Users expect the usage of each node to be balanced. More details can be referred to https://github.com/volcano-sh/volcano/blob/master/docs/design/usage-based-scheduling.md. (#2023, #2129 @william-wang )

Support Rescheduling Based on Real Node Load

This feature enables users to rebalance the node utilization based on real node resource usage reqularlly, which is quite suitable for long-running workloads such as deployment. All the rescheduling policies and check interval can be configured according to custom scenarios. More details can be referred to https://github.com/volcano-sh/volcano/blob/master/docs/design/rescheduling.md. (#2174, #2184 @Thor-wl )

Support Elastic Job Scheduling

This feature allows Volcano to schedule volcano job based on the [min,max] configuration in the job, which will improve resource utilization rate and shorten the execution time of training job. More details can be referred to https://github.com/volcano-sh/volcano/blob/master/docs/design/elastic-scheduler.md. (#2105, @qiankunli )

Add MPI Job Plugin

This feature provides a new volcano job plugin - MPI Plugin. It will be more convient for MPI users to make use of volcano job instead of manually making connections for hosts of different roles, registering required environment variables and so on. More details can be referred to https://github.com/volcano-sh/volcano/blob/master/docs/design/distributed-framework-plugins.md. (#2237, @hwdef )
