KEP of the Week

KEP-4815: DRA: Add support for partitionable devices

One of the original use cases of DRA was to dynamically create and allocate partitions of a full GPU device on demand. As DRA evolved into “structured parameters” this ability to dynamically partition devices has been lost. This KEP introduces the ability for “structured parameters” DRA to allocate both full devices and fixed-size partitions of full devices (across multiple dimensions). This happens through a new type called PartitionableDevice which has all the same fields as BasicDevice, plus two new fields Includes and ConsumesCapacityFrom. With these new fields, the scheduler has everything it needs to support the dynamic allocation of both full devices and their fixed-size partitions.

This KEP is aiming for alpha in the ongoing v1.32 release cycle.
