Editing HPC Bench Measurements

==HPC Bench==

===Installing HPC Bench===
[http://hpcbench.sourceforge.net/ Hpcbench Download]

<p>Using the site above download the Hpcbench.tar.gz </p>
<p>Place the Hpcbench.tar.gz file onto the laptops in the location you would like the Hpcbench folder to be</p>
<p> <strong>Note:</strong> Easiest to place it in the main users folder. If you followed the install tutorial it would be in the root directory.</p>

===Using HPC Bench===

[http://hpcbench.sourceforge.net/usage.html#udp Guide for HPC Bench options and usage]

*'''Start up'''
**./udpserver

*'''Test run command'''
**./udptest -ah (IP Address) -r (repetitions) -o (data text file)
*** -ah is IP Address is the receiving computer
*** -r is number of runs desired
*** -o is data text file or the path to the data text file you want the output to go to

==Output Formatting==
===Data File===
<p>When the program is run the data will be output as such:</p>
<br />
<p># UDP roundtrip time test DATE</p>
<p># localhost.localdomain <--> IP-ADDRESS</p>
<p># UDP-send-buffer: ## UDP-recv-buffer: ##</p>
<p># Message-size: # Iteration: #</p>
<p>UDP Round Trip Time (1) : ## usec</p>
<p>UDP Round Trip Time (2) : ## usec</p>
<p>...</p>
<p>UDP Round Trip Time (n) : ## usec</p>
<p>n trials with message size 64 Bytes</p>
<p>UDP RTT (64-byte) min/avg/max = ### / ### / ### usec</p>
<br />
<br />

===Formatting===
<p>To edit the file to get the output needed for the ROOT Programming use the following commands on the text file:</p>
<p><pre>sed 'n-1,nd' | sed '1,4d' filename.txt > output.txt</pre></p>   
<p><pre>cat data.txt | tr -d '(' | tr -d ')' | awk '{print $5 " " $7}' > output.txt</pre></p>

<p><strong>Note:</strong> Make sure you have a backup of the text files before performing any editing on them in terminal!</p>
<br>
<p> The first command removes the last two and first four lines of the file. </p>
<p> The second command removes the parentheses around the run # and only prints columns 5 and 7 which are the necessary values </p>
