[[PageOutline]] = Continuation Round 1 = In this round, I ran plastic-104 over the weekend as a simple test that anything at all was working. The raw logs are at http://www.gpolab.bbn.com/plastic-slices/continuation/round-1/. = plastic-104 = [PlasticSlices/Experiments#SteadyPerfUDP SteadyPerf UDP], using port=5104, time=518400, rate=3, and this table of client/server pairs: || '''client''' || '''server''' || '''server address''' || || ganel.gpolab.bbn.com || wings-openflow-2.wail.wisc.edu || server=10.42.104.95 || || wings-openflow-3.wail.wisc.edu || orbitplc2.orbit-lab.org || server=10.42.104.112 || || orbitplc1.orbit-lab.org || pl4.myplc.grnoc.iu.edu || server=10.42.104.72 || || pl5.myplc.grnoc.iu.edu || sardis.gpolab.bbn.com || server=10.42.104.53 || == One-time prep commands run on each client and server == {{{ sudo yum -y install iperf }}} == Commands run on each server == {{{ server= nice -n 19 iperf -u -B $server -p 5104 -s -i 1 }}} == Commands run on each client == {{{ server= nice -n 19 iperf -u -c $server -p 5104 -t 518400 -b 3M }}} == Results == Generated with {{{ subnet=104 for host in $(awk 'NR%2==1' ~/plastic-slices/logins/logins-plastic-$subnet.txt | sed -r -e 's/.+@//') ; do echo -e "$host:\n\n{{{" ; grep -A 10 -B 1 "Client connecting" pgenigpolabbbncom_plastic$subnet\@$host.log ; echo -e "}}}\n" ; done }}} and then edited slightly to remove artifacts (like control characters, my prompt, etc).
