=== Prerequisite === This sample experiment requires sandbox 7 (sb7.orbit-lab.org) and the two nodes (node1-1 & node1-2). === The tutorial experiment === This experiment is given in the attached script [attachment:wimax-tutorial2.rb wimax-tutorial2.rb]. Download this file to your home directory. To run this experiment: 1. ssh into sandbox 7 {{{ nilanjan@external2:~$ ssh sb7.orbit-lab.org }}} 2. Image node1-1 & node1-2 with wimax.ndz (this should be in the repository) {{{ nilanjan@console.sb7:~$ omf-5.2 load [1,1..2] wimax.ndz }}} The output of the imaging command should look similar to the following: {{{ nilanjan@console.sb7:~$ omf-5.2 load [1,1..2] wimax.ndz Imaging nodes: '[1,1..2]' with image 'wimax.ndz' (Domain: default from hostname) (Timeout: 800 sec.)

Once the imaging process is complete, we need to turn the nodes on {{{ nilanjan@console.sb7:~$ omf-5.2 tell on [1,1..2] }}} 4. Run the experiment script (from above) {{{ nilanjan@console.sb7:~$ omf-5.2 exec wimax-tutorial2.ndz }}} The output of the experiment script should be similar to the following: {{{ nilanjan@console.sb7:~$ omf-5.2 exec wimax-tutorial2.rb INFO NodeHandler: init OMF Experiment Controller 5.2.408 INFO NodeHandler: init Experiment ID: sb7.orbit-lab.org_2011_09_14_10_58_24 INFO NodeHandler: Web interface available at: http://10.17.0.10:4000 INFO Experiment: load system:exp:stdlib INFO property.resetDelay: value = 70 (Fixnum) INFO property.resetTries: value = 1 (Fixnum) INFO Experiment: load wimax-tutorial2.rb INFO whenAll: *: 'apps/app/status/@value' fires INFO exp: Give machines some time to warm up INFO exp: Request from Experiment Script: Wait for 10s....
