Abstract: Technologies for managing a single-producer and single-consumer ring include a producer of a compute node that is configured to allocate data buffers, produce work, and indicate that work has been produced. The compute node is configured to insert reference information for each of the allocated data buffers into respective elements of the ring and store the produced work into the data buffers. The compute node includes a consumer configured to request the produced work from the ring. The compute node is further configured to dequeue the reference information from each of the elements of the ring that correspond to the portion of data buffers in which the produced work has been stored, and set each of the elements of the ring for which the reference information has been dequeued to an empty (i.e., NULL) value. Other embodiments are described herein.

Abstract: In some examples, for process-to-process communication, such as in function linking, a virtual channel can be provisioned to provide virtual machine to virtual machine communications. In response to a transmit request from a source virtual machine, the virtual channel can cause a data copy from a source buffer associated with the source virtual machine without decryption or encryption. The virtual channel provisions a key identifier for the copied data. The destination virtual machine can receive an indication data is available and can cause the data to be decrypted using a key accessed using the key identifier and source address of the copied data. In addition, the data can be encrypted using a second, different key for storage in a destination buffer associated with the destination virtual machine. In some examples, the key identifier and source address is managed by the virtual channel and is not visible to virtual machine or hypervisor.

Abstract: Embodiments include apparatuses, methods, and systems including one or more servers and one or more storage devices, coupled with each other, to provide virtual storage service to store a file and meta data of the file for a client computing device. The file and the meta data of the file may be encrypted by the client computing device before providing to the virtual storage service. The file may be encrypted with a secret key of the client computing device, and the meta data of the file may be encrypted with a shared session key between the client computing device and the virtual storage service. The encrypted file may be stored in the one or more storage devices, and the encrypted meta data of the file may be stored in one or more secured areas of the one or more servers. Other embodiments may also be described and claimed.

Abstract: There is disclosed in an example, an endpoint apparatus for an interconnect, comprising: a mechanical and electrical interface to the interconnect; and one or more logic elements comprising an interface vector engine to: receive a first scalar transaction for the interface; determine that the first scalar transaction meets a criterion for vectorization; receive a second scalar transaction for the interface; determine that the second transaction meets the criterion for vectorization; vectorize the first scalar transaction and second scalar transaction into a vector transaction; and send the vector transaction via the electrical interface.

Abstract: Disclosed herein are systems and methods for isolating input/output computing resources. In some embodiments, a host device may include logic to identify a Process Address Space Identifier (PASID) for a process or container of the host device and logic to associate the PASID with an individual queue pair of a hardware device of the host device, wherein the queue pair includes two complementary queues and wherein the queue pair is owned by the process or container upon association with the PASID. Other embodiments may be disclosed and/or claimed.
