Continuation Round 6

In this round, I ran plastic-105 and plastic-106 for about N hours, with only GT and Wisconsin, to try to track down some issues with performance in Round 3 that seemed related to GT. This was just a repeat of Round 4.

The raw logs are at ​http://www.gpolab.bbn.com/plastic-slices/continuation/round-6/.

plastic-105

​SteadyPerf TCP, using port=5105, time=518400, and this table of client/server pairs:

client	server	server address
plnode1.cip.gatech.edu	wings-openflow-2.wail.wisc.edu	server=10.42.105.95
plnode2.cip.gatech.edu	wings-openflow-3.wail.wisc.edu	server=10.42.105.96

One-time prep commands run on each client and server

sudo yum -y install iperf

Commands run on each server

server=<ipaddr>
nice -n 19 iperf -B $server -p 5105 -s -i 1

Commands run on each client

server=<ipaddr>
nice -n 19 iperf -c $server -p 5105 -t 518400

Results

Generated with

subnet=105
for host in $(awk 'NR%2==1' ~/plastic-slices/logins/logins-plastic-$subnet.txt | sed -r -e 's/.+@//') ; do echo -e "$host:\n\n{{{" ; grep -A 5 -B 1 "Client connecting" pgenigpolabbbncom_plastic$subnet\@$host.log ; echo -e "}}}\n" ; done

and then edited slightly to remove artifacts (like control characters, my prompt, etc).

(because the summary of the results are in the client logs, which are the odd-numbered lines in the file)
