摘要： System, method, and apparatus for improving the performance of collective operations in High Performance Computing (HPC). Compute nodes in a networked HPC environment form collective groups to perform collective operations. A spanning tree is formed including the compute nodes and switches and links used to interconnect the compute nodes, wherein the spanning tree is configured such that there is only a single route between any pair of nodes in the tree. The compute nodes implement processes for performing the collective operations, which includes exchanging messages between processes executing on other compute nodes, wherein the messages contain indicia identifying collective operations they belong to. Each switch is configured to implement message forwarding operations for its portion of the spanning tree. Each of the nodes in the spanning tree implements a ratcheted cyclical state machine that is used for synchronizing collective operations, along with status messages that are exchanged between nodes. Transaction IDs are also used to detect out-of-order and lost messages.

摘要： Methods, apparatus, and systems for implementing hierarchical and lossless packet preemption and interleaving to reduce latency jitter in flow-controller packet-based networks. Fabric packets are divided into a plurality of data units, with data units for different fabric packets buffered in separate buffers. Data units are pulled from the buffers and added to a transmit stream in which groups of data units are interleaved. Upon receipt by a receiver, the groups of data units are separated out and buffered in separate buffers under which data units for the same fabric packets are grouped together. In one aspect, each buffer is associated with a respective virtual lane (VL), and the fabric packets are effectively transferred over fabric links using virtual lanes. VLs may have different levels of priority under which data units for fabric packets in higher-priority VLs may preempt fabric packets in lower-priority VLs. By transferring data units rather than entire packets, transmission of a packet can be temporarily paused in favor of a higher-priority packet. Multiple levels of preemption and interleaving in a nested manner are supported.

摘要： A shared I/O subsystem for a plurality of computer systems where a plurality of virtual I/O interfaces are communicatively coupled to the computer systems. Each of the computer systems includes a virtual adapter that communicates with one of the virtual I/O interfaces. The shared I/O subsystem also includes a plurality of I/O interfaces and a forwarding function. The forwarding function includes a plurality of forwarding table entries that logically arrange the shared I/O subsystem into one or more logical switches. Each of the logical switches communicatively couples one or more of the virtual I/O interfaces to one of the I/O interfaces. A logical switch receives a first I/O packet from one of the virtual I/O interfaces and directs the first I/O packet to at least one of the I/O interface and one or more of other ones of the virtual I/O interfaces. A logical switch also receives a second I/O packet from the I/O interface and directs the second I/O packet to one or more of the virtual I/O interfaces.

摘要： Method, apparatus, and systems for implementing flexible credit exchange within high performance fabrics. Available buffer space in a receive buffer on a receive-side of a link is managed and tracked at the transmit-side of the link using credits. Peer link interfaces coupled via a link are provided with receive buffer configuration information that specifies how the receive buffer space in each peer is partitioned and space allocated for each buffer, including a plurality of virtual lane (VL) buffers. Credits are used for tracking buffer space consumption and in credits are returned from the receive-side indicating freed buffer space. The peer link interfaces exchange credit organization information to inform the other peer of how much space each credit represents. In connection with data transfer over the link, the transmit-side de-allocates credits based on an amount of buffer space to be consumed in applicable buffers in the receive buffer. Upon space being freed in the receive buffer, the receive-side returns credit ACKnowledgements (ACKs) identifying a VL for which space has been freed.

The SA proxy logic includes provider logic that includes path record information of an associated subnet in communication with the computer network node; and provider interface logic to receive an address resolution request from at least one application that includes partial address information. The provider interface logic is also to determine at least one local port of the computer network node to enable packet routing associated with the address resolution request. The provider logic is also to determine at least one subnet associated with the address resolution request. The provider interface logic is also to determine at least one provider logic to utilize to obtain the path record information for at least one subnet associated with the address resolution request. The provider interface logic is also to generate an address resolution response that includes a resolved address, that includes the path record information, and the identity of at least one local port to enable the at least one application to route data packets through the at least one determined subnet.
