<div class="WordSection1">
<p class="MsoNormal">I have two head nodes, each head node has 6 workers.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I split the job up into two groups of files, the idea being Head-1 does scans/files 1-6 and Head-2 does scans/files 7-11.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I create two separate input files with different file lists etc. Also two separate thread and machine files appropriate to the two different groups of ip addresses.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">head-1, worker-1-1, worker-1-2 … worker-1-6<o:p></o:p></p>
<p class="MsoNormal">head-2, worker-2-1 ….. worker-2-6<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So set two jobs running in parallel<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Head-1 > mpirun -machinefile machines-1 -np 5 mpifxcorr hw03_1.input<o:p></o:p></p>
<p class="MsoNormal">Head-2 > mpirun -machinefile machines-2 -np 5 mpifxcorr hw03_2.input<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now all machines are in the same subnet. I am guessing some communication is going on as Head-2 seem’s to wait while Head-1 processes files 1-6, once Head -1 has finished Head-2 gets busy doing files 7-11.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there any way to have Head-1 and Head-2 running at the same time ? ie Head-2 doesn’t wait for Head-1 to finish !<o:p></o:p></p>
