<p class=MsoNormal>Dear PWSCF Users,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am using QE-ver 4.0.3 on my cluster. I submitted one
job from the the 2<sup>nd</sup> node (I call the head node as the 1<sup>st</sup>
node). This job used 40CPUs, with the distribution being 5 nodes (nodes #3
to #9, and 6CPUs/node) and 1 node (node #10, and 4CPUs/node). When I used
‘top’ command on node#2 to see the jobs listing, memory uses,…I
usually saw lines of ‘nsfd’ appear on the ‘Command’
column. What ‘nsfd’ means? <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The reason I have this question is that the machine is
usually slower (i.e. hangs up for 20 seconds or more) if I submit a 2<sup>nd</sup>
job from node#2, but use other nodes (say nodes #11 to 17). Having this 2<sup>nd</sup>
job running at the same time with the 1<sup>st</sup> job, I saw more ‘nsfd’
lines appear, and the machine is slower. I appreciate if you could
explain to me what “nsfd” means. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thank you,<o:p></o:p></p>
