Introduction¶

The Run:ai Administration User Interface provides a set of dashboards that help you monitor Clusters, Cluster Nodes, Projects, and Workloads. This document provides the key metrics to monitor, how to assess them as well as suggested actions.

Dashboards are used by system administrators to analyze and diagnose issues that relate to:

• Physical Resources.
• Organization resource allocation and utilization.
• Usage characteristics.

System administrators need to know important information about the physical resources that are currently being used. Important information such as:

• Resource health.
• Available resources and their distribution.
• Is there a lack of resources.
• Are resources being utilized correctly.

With this information, system administrators can hone in on:

• How resources are allocated across the organization.
• How the different organizational units utilized quotas and resources within those quotas.
• The actual performance of the organizational units.

These dashboards give system administrators the ability to drill down to see details of the different types of workloads that each of the organizational units is running. These usage and performance metrics ensure that system administrators can then take actions to correct issues that affect performance.

There are 5 dashboards:

• GPU/CPU Overview dashboard—Provides information about what is happening right now in the cluster.
• Quota Management dashboard—Provides information about quota utilization.
• Analytics dashboard—Provides long term analysis of cluster behavior.
• Multi-Cluster Overview dashboard—Provides a more holistic, multi-cluster view of what is happening right now. The dashboard is intended for organizations that have more than one connected cluster.
• Consumption dashboard—Provides information about resource consumption.

GPU/CPU Overview Dashboard (New and legacy)¶

The Overview dashboard provides information about what is happening right now in the cluster. Administrators can view high-level information on the state of the cluster. The dashboard has two tabs that change the display to provide a focused view for GPU Dashboards (default view) and CPU Dashboards.

GPU Dashboard¶

The GPU dashboard displays specific information for GPU based nodes, node-pools, clusters, or tenants. These dashboards also include additional metrics that specific to GPU based environments. The dashboard contains tiles that show information about specific resource allocation and performance metrics. The tiles are interactive allowing you to link directly to the assets or drill down to specific scopes. Use the time frame selector to choose a time frame for all the tiles in the dashboard.

The dashboard has the following tiles:

• Ready nodes—displays GPU nodes that are in the ready state.
• Ready GPU devices—displays the number of GPUs in nodes that are in the ready state.
• Allocated GPU compute—displays the total number of GPUs allocated from all the nodes.
• Running workloads—displays the number of running workloads.
• Pending workloads—displays the number of workloads in the pending status.
• Allocation ration by node pool—displays the percentage of GPUs allocated per node pool. Hover over the bar for detailed information. Use the scope selected at the bottom of the graph to drill down for more details.
• Free resources by node pool—the graph displays the amount of free resources per node pool. Press a entry in the graph for more details. Hover over the resource bubbles for specific details for the workers in the node. Use the ellipsis to download the graph as a CSV file.
• Resource allocation by workload type—displays the resource allocation by workload type. Hover over the bar for detailed information. Use the scope selected at the bottom of the graph to drill down for more details. Use the ellipsis to download the graph as a CSV file.

• Workload Count per CPU Compute Utilization—
• 5 longest running workloads—displays up to 5 of workloads that have the longest running time.

Analysis and Suggested actions:

Workloads with an Error¶

Search for Workloads with an error status. These Workloads may be holding GPUs/CPUs without actually using them.

Analysis and Suggested actions:

Search for workloads with an Error status on the Workloads view and discuss with the Job owner. Consider deleting these Workloads to free up the resources for other users.

Workloads with a Long Duration¶

View list of 5 longest Workloads.

Analysis and Suggested actions:

Job Queue¶

Identify queueing bottlenecks.

Analysis and Suggested actions:

Also, check the command that the user used to submit the job. The Researcher may have requested a specific Node for that Job.

Analytics Dashboard¶

The Analytics dashboard provides means for viewing historical data on cluster information such as:

• Utilization across the cluster
• GPU usage by different Projects, including allocation and utilization, broken down into interactive and training Workloads
• Breakdown of running Workloads into interactive, training, and GPU versus CPU-only Workloads, including information on queueing (number of pending Workloads and requested GPUs),
• Status of Nodes in terms of availability and allocated and utilized resources.

The dashboard has a dropdown filter for node pools and Departments. From the dropdown, select one or more node pools. The default setting is all.

The information presented in Analytics can be used in different ways for identifying problems and fixing them. Below are a few examples.

Node Downtime¶

View the overall available resources per Node and identify cases where a Node is down and there was a reduction in the number of available resources.

How to: view the following panel.

Analysis and Suggested actions:

Filter according to time range to understand for how long the Node is down.

GPU Allocation¶

Track GPU allocation across time.

How to: view the following panels.

The panel on the right-hand side shows the cluster-wide GPU allocation and utilization versus time, whereas the panels on the left-hand side show the cluster-wide GPU allocation and utilization averaged across the filtered time range.

Analysis and Suggested actions:

If the allocation is too low for a long period, work with users to run more workloads and to better utilize the Cluster.

Track GPU utilization¶

Track whether Researchers efficiently use the GPU resources they have allocated for themselves.

How to: view the following panel:

Analysis and Suggested actions:

If utilization is too low for a long period, you will want to identify the source of the problem:

• Go to “Average GPU Allocation & Utilization”
• Look for Projects with large GPU allocations for interactive Workloads or Projects that poorly utilize their training Workloads. Users tend to poorly utilize their GPUs in interactive sessions because of the dev & debug nature of their work which typically is an iterative process with long idle GPU time. On many occasions users also don’t shut down their interactive Workloads, holding their GPUs idle and preventing others from using them.

Training vs. Interactive -- Researcher maturity¶

Track the number of running Workloads and the breakdown into interactive, training, and CPU-only Workloads.

How to: view the following panel:

Analysis and Suggested actions:

We would want to encourage users to run more training Workloads than interactive Workloads, as it is the key to achieving high GPU utilization across the Cluster:

• Training Workloads run to completion and free up their resources automatically when training ends
• Training Workloads can be preempted, queued, and resumed automatically by the Run:ai system according to predefined policies which increases fairness and Cluster utilization.

Pending Queue Size¶

Track how long is the queue for pending Workloads

How to: view the following panels:

Analysis and Suggested actions:

Consider buying more GPUs:

• When there are too many Workloads are waiting in queue for too long.
• With a large number of requested GPUs.
• While the Cluster is fully loaded and well utilized.

CPU & Memory Utilization¶

Track CPU and memory Node utilization and identify times where the load on specific Nodes is high.

How to: view the following panel:

Analysis and Suggested actions:

If the load on specific Nodes is too high, it may cause problems with the proper operation of the Cluster and the way workloads are running.

Consider adding more CPUs, or adding additional CPU-only nodes for Workloads that do only CPU processing.

Multi-Cluster overview dashboard¶

Provides a holistic, aggregated view across Clusters, including information about Cluster and Node utilization, available resources, and allocated resources. With this dashboard, you can identify Clusters that are down or underutilized and go to the Overview of that Cluster to explore further.

Consumption dashboard¶

This dashboard enables users and admins to view consumption usage using run:AI services. The dashboard provides views based on configurable filters and timelines. The dashboard also provides costing analysis for GPU, CPU, and memory costs for the system.

The dashboard has 4 tiles for:

• Cumulative GPU allocation per Project or Department
• Cumulative CPU allocation per Project or Department
• Cumulative memory allocation per Project or Department
• Consumption types

Use the drop down menus at the top of the dashboard to apply filters for:

• Project or department
• Per project (single, multiple, or all)
• Per department (single, multiple or all)
• Per cluster (single, multiple, all)

To enable the Consumption Dashboard:
