A number of changes have been made to the Scheduler architecture in order to increase scalability and provide an effective way for users to view and manage large numbers of tasks.
The most significant change is that Tasks are no longer defined within Task Groups. Instead, each Task is now a separate object. Further changes to Tasks and their relationships to other objects include:
For further information on these changes, please see:
The AWS Source Templates now support provisioning as an AWS Cluster Placement Group. A Cluster Placement Group is a grouping of Instances within a single Availability Zone, allowing for higher throughput and lower latency.
To provision as a Cluster Placement Group, check the Create Cluster Placement Group option when creating or updating the relevant AWS Source Template. This option is available for both AWS On-Demand and AWS Spot.

It is now possible to view Task Groups in a table, instead of a dependency diagram. The tabular view provides a summary of Task Group details, and is particularly useful when dealing with large numbers of Task Groups. You can use a toggle to switch between the two views.
Note that the header of the Task Group section also provides access to a new Task Search feature, described below.
The Task Search facility enables you to filter large numbers of tasks by specific criteria. Click on Search all tasks in the Task Group section header to open a pane of search options.
You can use this pane to filter Tasks by Name, Status, the time they started or finished, and more. When searching by Name or Tag, the search supports Regex syntax, providing the flexibility needed to manage potentially thousands of Tasks.
After searching, the Task Search pane minimises in order to avoid screen clutter, showing only your selected search options. To search again, click on Search all tasks to reopen it.
The Portal now supports the deprovisioning feature introduced in the 3.0 release. When terminating an Instance in a Compute Requirement, you can now choose whether to deprovision that instance. If you deprovision an Instance, the Instance Count reduces. Reprovisioning, whether manual using the Reprovision icon or automatic via Maintain Instance Count, will attempt to provision the new, lower number of instances.
