<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt"><div>Hi Kaz,</div><div><br></div><div>I found the following about tours rank from http://wiki.mcs.anl.gov/zeptoos/index.php/FAQ and want to double check with you still this information valid. <br></div><h3 style="color: rgb(0, 0, 191);"> <span class="mw-headline">Torus rank</span>:-</h3>
<h3 style="color: rgb(0, 0, 191);"><span style="font-weight: normal;">A torus rank is a number identifying a compute node within a whole
partition. In a way, it is much "nicer" than a pset rank since it is
unique within a job and it also starts from </span><tt style="font-weight: normal;">0</tt>. <br>
</h3>
<div style="color: rgb(0, 0, 191);">- A shell script can easily calculate it from other fields:
</div>
<pre style="color: rgb(0, 0, 191);">TORUS_RANK=`echo $BG_PSETORG | awk "{print \\$1 + \\$2 * $BG_XSIZE + \
\\$3 * $BG_XSIZE * $BG_YSIZE}"</pre>
<div><br></div><div>It would be great if you can make sure that the <span style="color: rgb(192, 0, 0); font-weight: bold;">tours rank is unique within a partition and always starts from zero </span><span style="color: rgb(192, 0, 0);">regardless of the following</span>.</div><div><br></div><div> - Partition size (fraction of pset / multiple of psets / both )<br></div><div> - Platform (Surveyor / Intrepid)</div><div> - Kernel profiles.</div><div><br></div><div><br></div><div>(Note: I am asking this in order to figure out a easy way to deploy MosaStore at BG/P at large scale. I did few tests with different partition size in Surveyor and it seems the tours rank is unique and always starts from zero.)<br></div><div><br></div><div>Thank you</div><div>Emalayan<br></div><br><pre style="color: rgb(0, 0, 191);"><br style="color: rgb(0, 0, 0);"><span style="color: rgb(0, 0, 0);"></span><br></pre></div></body></html>
