The Trimaran plugins utilize a load-watcher to access resource utilization data via metrics providers. Currently, the load-watcher supports three metrics providers: Kubernetes Metrics Server, Prometheus Server, and SignalFx. There are two modes for a Trimaran plugin to use the load-watcher: as a service or as a library.

Trimaran: Real Load Aware Scheduling
KEP - Trimaran: Real Load Aware ... To achieve this goal, we can make the Kubernetes scheduler aware of the gap between resource allocation and actual resource utilization. Taking advantage of the gap may help pack pods more efficiently, while the default scheduler that only considers pod requests and allocable resources on nodes cannot.
KEP
Kubernetes provides a declarative resource model that core components (scheduler and kubelet) honor to behave consistently and satisfy QoS guarantees. However, using this model can lead to low-utilization of the cluster for the following reasons: It is hard for users to estimate accurate resource usage for applications.
Improving the Resource Efficiency for OpenShift Clusters Via Trimaran
With the Trimaran scheduler plug-ins, users can achieve basic load-aware scheduling that is not implemented in the default Kubernetes scheduler. Trimaran plug-ins can either balance the usage on nodes so that all nodes reach a certain percentage of utilization, or it can prioritize nodes that have lower risk when overcommitting the pods.
Trimaran: Real Load Aware Scheduling in Kubernetes
Explore real load-aware scheduling in Kubernetes through this 33-minute conference talk presented by Abdul Qadeer from PayPal and Chen Wang from IBM. Discover how the Trimaran framework introduces two plugins, TargetLoadPacking and LoadVariationRiskBalancing, to enhance the native Kubernetes scheduler.

Kubernetes Scheduler
In Kubernetes, scheduling refers to making sure that Pods are matched to Nodes so that Kubelet can run them. Scheduling overview A scheduler watches for newly created Pods that have no Node assigned. For every Pod that the scheduler discovers, the scheduler becomes responsible for finding the best Node for that Pod to run on. The scheduler reaches this placement decision taking into account ...
