This commit implements atomic operations for the armv7a architecture using gcc inline assembly. This offers higher performance compared to pthread mutexes. Tested on an am3517 evm, clocked at 600MHz: ./inproc_thr 200 1000000 ------------------------ 53-60K messages / sec, pthread mutexes 73-90K messages / sec, assembly atomic ops ./inproc_lat 200 1000000 ------------------------ average latency: 42.234 [us], pthread mutexes average latency: 35.496 [us], assembly atomic ops
Welcome ------- The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more. Building and installation ------------------------- See the INSTALL file included with the distribution. Resources --------- Extensive documentation is provided with the distribution. Refer to doc/zmq.html, or "man zmq" after you have installed 0MQ on your system.
