Abstract: Disclosed embodiments relate to encoded inline capabilities. In one example, a system includes a trusted execution environment (TEE) to partition an address space within a memory into a plurality of compartments each associated with code to execute a function, the TEE further to assign a message object in a heap to each compartment, receive a request from a first compartment to send a message block to a specified destination compartment, respond to the request by authenticating the request, generating a corresponding encoded capability, conveying the encoded capability to the destination compartment, and scheduling the destination compartment to respond to the request, and subsequently, respond to a check capability request from the destination compartment by checking the encoded capability and, when the check passes, providing a memory address to access the message block, and, otherwise, generating a fault, wherein each compartment is isolated from other compartments.

Abstract: Technologies for composing a managed node with multiple processors on multiple compute sleds to cooperatively execute a workload include a memory, one or more processors connected to the memory, and an accelerator. The accelerator further includes a coherence logic unit that is configured to receive a node configuration request to execute a workload. The node configuration request identifies the compute sled and a second compute sled to be included in a managed node. The coherence logic unit is further configured to modify a portion of local working data associated with the workload on the compute sled in the memory with the one or more processors of the compute sled, determine coherence data indicative of the modification made by the one or more processors of the compute sled to the local working data in the memory, and send the coherence data to the second compute sled of the managed node.
