SYSTEM AND METHOD FOR MULTIPLE SENDER SUPPORT IN LOW LATENCY FIFO MESSAGING USING RDMA

摘要

SYSTEM AND METHOD FOR MULTIPLE SENDER SUPPORT IN LOW LATENCY FIFO MESSAGING USING RDMA System for transmitting and receiving multiple messages between multiple senders and at least one receiver in inter-process communication with low latencies and high throughput using Remote Direct Memory Access (RDMA) through InfiniBand verbs library is described. System comprises message queue library which allows messaging in lockless manner, Network Interface Card enabled for RDMA, and RDMA based remote sender processes to synchronize sub-queues. Transmitting system maps each remote sender process to First in First Out (FIFO) sub-queue of host node and corresponding FIFO sub queue of receiving node, assigns each user to a sub-queue, receives messages and arranges messages in FIFO sub-queue for each user and transmits messages from each FIFO sub queue of host node to corresponding FIFO sub-queue of receiver node. Receiving system receives messages and arranges in FIFO sub-queue for each user and reads messages from each FIFO sub-queue by round-robin technique in FIFO mode.
