= Testing the fcast application that uses ALC reliable multicast = All scripts are in gw.orbit-lab.org:/home/kishore/Test-MCL (~/ in the rest of the document is equivalent to /home/kishore). == Important scripts == * start-mcasttx.sh - This is run on the sending node. * start-mcastrx.sh - This is run on all receiving nodes. * test-512B.sh - This is the main script that runs the above scripts on the sending and receiving nodes as well as collects data on the experiment run. == Steps to run Experiment == * Image nodes on the grid - [3,1] and all nodes from [4,1] to [15,20] (except [5,10] which is a dead node). There is a ruby script in my home directory called imageSubset.rb (which images all nodes from [4,1] to [15,20] except [5,10]), which you can use. {{{ imageNodes [3,1] baseline-fcast.ndz ruby imageSubset.rb }}} * Turn these nodes ON - {{{ wget -O - "http://cmc:5012/cmc/nodeSet?nodes=[4..15,1..20]" wget -O - "http://cmc:5012/cmc/nodeSet?nodes=[3,1]" }}} * Once the nodes are ON, * cd ~/Test-MCL * mkdir directory-for-this-run - {{{ mkdir 240nodes-run12 }}} * Make sure the sender (node3-1) has the directory you wish to transfer using multicast (for e.g. ~/Test-MCL/512B contains 10000 512 byte files, ~/Test-MCL/512B-5000 contains 5000 512 byte files). {{{ cd ~/Test-MCL scp -r 512B-5000 root@node3-1:/root/ }}} * Modify start-mcasttx.sh according to the directory you want to transfer - for e.g. to transfer 512B-5000, start-mcasttx.sh should contain the following command: {{{ fcast -R -send -a225.1.2.3/2323 -v0 -ospeed -plan -force /root/512B-5000 &> $1 & }}} * Copy start-mcasttx.sh to node3-1 (sender): {{{ cd ~/Test-MCL scp start-mcasttx.sh root@node3-1:/root/ }}} * Copy start-mcastrx.sh to all receiving nodes: {{{ cd ~/Test-MCL ./copyfile.pl start-mcastrx.sh }}} * Start experiment: {{{ cd ~/Test-MCL ./test-512B.sh 240nodes-run12 &> 240nodes-run12/240nodes-run12.txt }}}
