Abstract: A system, method, and apparatus may provide one or more tangible, nontransitory computer-readable storage media having stored thereon executable instructions to instruct a processor to: stripe an outgoing network message into two or more pieces; send a first piece to a receiver via a first network interface card (NIC), and a second piece to the receiver via a second NIC; and upon determining that the receiver failed to receive a piece of the outgoing network message, replay the piece that the receiver failed to receive via a third NIC.

Abstract: There is included in one example a switch, including: an ingress port to receive data from a source host; a first egress port to send data to a destination host; a second egress port to send data to the source host; and a congestion notification generator (CNG) including: a congestion detector to compute bandwidth consumption of a flow associated with a packet received on the ingress port and assigned to the first egress port, and determine based on the computed bandwidth consumption that the flow is congested; a flow extractor to extract a flow identifier of the flow from the packet; a throttle calculator to calculate a quantitative flow throttle value for the flow; and a header builder to build a congestion notification packet to instruct the source host to throttle the flow.

Abstract: Particular embodiments described herein provide for a system for enabling the communication of a large message using multiple network interface controllers (NICs). The system can be configured to determine that a message to communicate to a receiver over a network is above a threshold, determine a plurality of NICs to be used to communicate the message, create a manifest that includes an identifier of each of the plurality of NICs, and communicate the manifest to the receiver using a multi-unit message. In an example, the multi-unit message is communicated using a PUT command and the receiver can analyze the manifest and use a GET command to pull the message from the plurality of NICs.

Abstract: Particular embodiments described herein provide for a system for enabling the communication of a message using a network interface controller (NICs) on a subnet. In an example, the system is applicable to hardware offload NICs such as those implementing the Portals protocol. The system can be configured to determine a NIC in a first subnet to be used to communicate a message, where the NIC is configured to comply with a message passing interface protocol, create a manifest that includes an identifier of the NICs and a subnet ID that identifies the first subnet, and communicate the manifest to the receiver.

Abstract: A data processing system includes a plurality of processor resources, a manager, and a power distributor. Each of the plurality of data processor cores is operable at a selected one of a plurality of performance states. The manager assigns each of a plurality of program elements to one of the plurality of processor resources, and synchronizing the program elements using barriers. The power distributor is coupled to the manager and to the plurality of processor resources, and assigns a performance state to each of the plurality of processor resources within an overall power budget, and in response to detecting that a program element assigned to a first processor resource is at a barrier, increases the performance state of a second processor resource that is not at the barrier within the overall power budget.
