22 # Mnemonic: run_multi_test.ksh
23 # Abstract: This is a simple script to set up and run the basic send/receive
24 # processes for some library validation on top of nano/nng. This
25 # particular tests starts several receivers and creates a route table
26 # which causes messages to be sent to all receivers in parallel
27 # (forcing message cloning internally in RMr).
28 # It should be possible to clone the repo, switch to this directory
29 # and execute 'ksh run -B' which will build RMr, make the sender and
30 # recevier then run the basic test.
32 # Example command line:
33 # ksh ./run_multi_test.ksh # default 10 messages at 1 msg/sec
34 # ksh ./run_multi_test.ksh -N # default but with nanomsg lib
35 # ksh ./run_multi_test.ksh -d 100 -n 10000 # send 10k messages with 100ms delay between
38 # Author: E. Scott Daniels
39 # ---------------------------------------------------------------------------------
42 # The sender and receivers are run asynch. Their exit statuses are captured in a
43 # file in order for the 'main' to pick them up easily.
