摘要： A method for communication includes inputting from a host processor to a network interface device a sequence of work requests indicative of operations to be carried out by the network interface device with respect to a plurality of the connections. The device looks ahead through the sequence in order to identify at least first and second operations that are to be carried out with respect to one of the connections in response to first and second work requests, respectively, wherein the second work request does not immediately follow the first work request in the sequence. The device loads the context data for the one of the connections from a host memory into a context cache, and performs at least the first and second operations sequentially while the context data are held in the cache.

摘要： Cache apparatus, including first and second cache memories, coupled to receive and hold context information from an external memory with respect to tasks, each task activated by one or more activating events, so that the context information is available for access by a processor in performing the tasks. The cache apparatus further includes a mapper, which is coupled to receive a classification of the tasks as fast and slow tasks. The mapper is adapted, upon receipt of one of the activating events for one of the fast tasks to be performed by the processor, to cause the context information with respect thereto to be received in the first cache memory, and upon receipt of one of the activating events for one of the slow tasks to be performed by the processor, to cause the context information with respect thereto to be received in the second cache memory.

摘要： Aspects of a high reliability system for transporting information across a network via a TCP tunnel are presented. The TCP tunnel may include a plurality of TCP connections that may be logically associated with a single TCP tunnel. At least a portion of the plurality of TCP connections may be associated with each of a plurality of different network interfaces. In a fault tolerant system, at least a current portion of a plurality of messages communicated via an RDMA connection may be transported by a current TCP connection associated with a current network interface located at a current RNIC. In the event of a subsequent failure in the current TCP connection a subsequent portion of the plurality of messages may be communicated via a subsequent TCP connection associated with a different network interface. The different network interface may be located at the current RNIC or at a subsequent RNIC.
