<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica">I am using the dsh command on an OSX cluster and would like to read in the node number from within the executed program. For example, with the Sun Grid Engine, I would run the following command:</p>
<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><br></p>
<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica">/share/bin/R "--args $SEGMENTS $SGE_TASK_ID" < testR.r</p>
<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><br></p>
<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica">and in the testR.r file, I was able to read the Task ID/node number and use it to parallelize my code. Which variable in the dsh command will let me read the node number?</p>
