OPTIONS
-i IF use network interface IF (default: eth0)
-b 100|1000 network bandwidth (100Mbps/1000Gbps) for calculating load
% given load in bytes/second (default: 1000)
-d DIR use DIR on remote (default: PWD)
-p provision required binaries in DIR (default: false)
first ssh's in to try mkdir -p DIR, then follows up with scp
-t DUR run for DUR seconds per size (default 20)
-a ASYNCLIST run for delivery async settings ASYNCLIST (default: "0 1")
-m MODELIST run with subscriber mode settings MODELIST (default: "-1 0 1")
-s SIZELIST run for sizes in SIZELIST (default: "0 16 32 64 128 256")
-l LOOPBACK enable multicast loopback (true/false, default: true)
-o DIR store results in dir.N where N is number of nodes
Runs throughput-test with the specified options for each prefix of remote nodes.
