Abstract: There is disclosed a computing apparatus, including: a hardware platform; an interface to a computer expansion bus; logic configured to operate on the hardware platform to: provision an unshaded memory queue, including a dedicated memory window for the computer expansion bus; and provision a descriptor ring, the descriptor ring configured to receive a descriptor, identify the descriptor as a chain descriptor targeted to a descriptor chain, identify a general descriptor unit (GDU) of the chain descriptor as having a device identifier (DID) matching the computing apparatus, process a workload of the GDU according to a private data field of the GDU, and forward the chain descriptor to a next-hop device via a switch fabric of the computer expansion bus, including bypassing a root complex of the computer expansion bus.

Abstract: Examples described herein relate to a reliable transport protocol for packet transmission using an Address Family of an eXpress Data Path (AF_XDP) queue framework, wherein the AF_XDP queue framework is to provide a queue for received packet receipt acknowledgements (ACKs). In some examples, an AF_XDP socket is to connect a service with a driver for the network device, one or more queues are associated with the AF_XDP socket, and at least one of the one or more queues comprises a waiting queue for received packet receipt ACKs. In some examples, at least one of the one or more queues is to identify one or more packets for which ACKs have been received. In some examples, the network device is to re-transmit a packet identified by a descriptor in the waiting queue based on non-receipt of an ACK associated with the packet from a receiver.

Abstract: A computing device includes last level cache (LLC) for processing cores and a separate input/output (I/O) LLC for use in facilitating data transfers between the computing device and one or more I/O devices. The I/O LLC is configured to include a set of partitions corresponding to a set of classes. Usage of the partitions in the set of partitions is monitored and the set of partitions is dynamically adjusted based on the usage. A process in a particular one of the classes makes a data request and a particular one of the partitions associated with the particular class is used in the data request.

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: Examples described herein relate to a network device apparatus that includes a network interface card to process a received packet. In some examples, based on the received packet only including one or more frames for which acknowledgement of receipt is offloaded to the network interface card, generate an acknowledgement (ACK) message to acknowledge receipt of the received packet. In some examples, a frame for which acknowledgement of receipt is offloaded to the network interface card comprises a STREAM frame compatible with quick User Datagram Protocol (UDP) Internet Connections (QUIC). In some examples, a computing platform is coupled to the network interface card. In some examples, based on the received packet only including any frame for which acknowledgement of receipt is not offloaded to the network interface, the computing platform is to generate an ACK message for the received packet.
