    摘要： A method and apparatus for distributed parallel messaging in a parallel computing system. A plurality of DMA engine units are configured in a multiprocessor system to operate in parallel, one DMA engine unit for transferring a current packet received at a network reception queue to a memory location in a memory FIFO (rmFIFO) region of a memory. A control unit implements logic to determine whether any prior received packet destined for that rmFIFO is still in a process of being stored in the associated memory by another DMA engine unit of the plurality, and prevent the one DMA engine unit from indicating completion of storing the current received packet in the reception memory FIFO (rmFIFO) until all prior received packets destined for that rmFIFO are completely stored by the other DMA engine units. Thus, there is provided non-locking support so that multiple packets destined for a single rmFIFO are transferred and stored in parallel to predetermined locations in a memory.

    摘要： According to one embodiment of the present invention, a system for operating memory includes a first node coupled to a second node by a network, the system configured to perform a method including receiving the remote transaction message from the second node in a processing element in the first node via the network, wherein the remote transaction message bypasses a main processor in the first node as it is transmitted to the processing element. In addition, the method includes accessing, by the processing element, data from a location in a memory in the first node based on the remote transaction message, and performing, by the processing element, computations based on the data and the remote transaction message.
