摘要： In an embodiment, a send thread receives an identifier that identifies a destination node and a pointer to data. The send thread creates a first send request in response to the receipt of the identifier and the data pointer. The send thread selects a selected channel from among a plurality of channels. The selected channel comprises a selected hand-off queue and an identification of a selected message unit. Each of the channels identifies a different message unit. The selected hand-off queue is randomly accessible. If the selected hand-off queue contains an available entry, the send thread adds the first send request to the selected hand-off queue. If the selected hand-off queue does not contain an available entry, the send thread removes a second send request from the selected hand-off queue and sends the second send request to the selected message unit.

摘要： A system, method and computer program product for performing various store-operate instructions in a parallel computing environment that includes a plurality of processors and at least one cache memory device. A queue in the system receives, from a processor, a store-operate instruction that specifies under which condition a cache coherence operation is to be invoked. A hardware unit in the system runs the received store-operate instruction. The hardware unit evaluates whether a result of the running the received store-operate instruction satisfies the condition. The hardware unit invokes a cache coherence operation on a cache memory address associated with the received store-operate instruction if the result satisfies the condition. Otherwise, the hardware unit does not invoke the cache coherence operation on the cache memory device.

摘要： The density of components in integrated circuits (ICs) is increasing with time. The density of heat generated by the components is similarly increasing. Maintaining the temperature of the components at reliable operating levels requires increased thermal transfer rates from the components to the IC package exterior. Dielectric materials used in interconnect regions have lower thermal conductivity than silicon dioxide. This invention comprises a heat pipe located in the interconnect region of an IC to transfer heat generated by components in the IC substrate to metal plugs located on the top surface of the IC, where the heat is easily conducted to the exterior of the IC package. Refinements such as a wicking liner or reticulated inner surface will increase the thermal transfer efficiency of the heat pipe. Strengthening elements in the interior of the heat pipe will provide robustness to mechanical stress during IC manufacture.

摘要： A method for passing messages in a parallel computer system constructed as a plurality of compute nodes interconnected as a network where each compute node includes a DMA engine but includes only a limited number of byte counters for tracking a number of bytes that are sent or received by the DMA engine, where the byte counters may be used in shared counter or exclusive counter modes of operation. The method includes using rendezvous protocol, a source compute node deterministically sending a request to send (RTS) message with a single RTS descriptor using an exclusive injection counter to track both the RTS message and message data to be sent in association with the RTS message, to a destination compute node such that the RTS descriptor indicates to the destination compute node that the message data will be adaptively routed to the destination node. Using one DMA FIFO at the source compute node, the RTS descriptors are maintained for rendezvous messages destined for the destination compute node to ensure proper message data ordering thereat. Using a reception counter at a DMA engine, the destination compute node tracks reception of the RTS and associated message data and sends a clear to send (CTS) message to the source node in a rendezvous protocol form of a remote get to accept the RTS message and message data and processing the remote get (CTS) by the source compute node DMA engine to provide the message data to be sent.

摘要： Disclosed is a mechanism on receiving processors in a parallel computing system for providing order to data packets received from a broadcast call and to distinguish data packets received at nodes from several incoming asynchronous broadcast messages where header space is limited. In the present invention, processors at lower leafs of a tree do not need to obtain a broadcast message by directly accessing the data in a root processor's buffer. Instead, each subsequent intermediate node's rank id information is squeezed into the software header of packet headers. In turn, the entire broadcast message is not transferred from the root processor to each processor in a communicator but instead is replicated on several intermediate nodes which then replicated the message to nodes in lower leafs. Hence, the intermediate compute nodes become “virtual root compute nodes” for the purpose of replicating the broadcast message to lower levels of a tree.
摘要翻译：公开了一种用于在并行计算系统中接收处理器的机制，用于向从广播呼叫接收的数据分组提供命令，并且将节点处接收到的数据分组与限制报头空间的若干输入异步广播消息进行区分。在本发明中，树的较低叶处理器不需要通过直接访问根处理器的缓冲器中的数据而获得广播消息。相反，每个后续的中间节点的等级id信息被挤压到分组头部的软件头部中。反过来，整个广播消息不是从根处理器传送到通信器中的每个处理器，而是复制在几个中间节点上，然后将消息复制到较低叶中的节点。因此，为了将广播消息复制到树的较低级别，中间计算节点变为“虚拟根计算节点”。

摘要： A method of achieving route optimization (RO) when a dual capable mobile Internet protocol version 6 (MIPv6) mobile node is connected with an IPv4-only network allows RO of packets to traverse a shorter route than the default one through the home agent (HA) using bidirectional tunneling, and leads to better bandwidth utilization. The method of RO with a dual MIPV6 node in an IPV4-only network includes updating the HA with an IPv4 address of the MN and deregistering a binding update (BU) with a corresponding node (CN) via the HA; informing the CN about its IPv4 address and receiving the CN's IPv4 address in reply; checking reachability of the CN in its IPv4 address using an IPv6-in-IPv4 tunnel; and sending and receiving Ipv6 data packets to/from the CN using a v4 tunnel.
