Abstract
Systems and methods are disclosed for data protection in a cluster of data processing accelerators (DPAs) using dynamic partitioning of DPAs into, or out of, one or more groups of DPAs in the cluster. A host device instructs each DPA in the cluster to link, or unlink, with one or more DPAs in the cluster to establish groups of DPAs in the cluster. A DPA that is not linked to any DPA is set to a low-power mode. Once grouped, the host device and a DPA can access all resources of the DPA. DPAs in the same group as a first DPA can access non-secure resources, but not secure resources, of the first DPA. DPAs in a different group from the first DPA cannot access any resources of the first DPA. A scheduler in the host device allocates processing tasks for one application or user to a group.
