<p>If your ini file is not part of the simfactory checkout (i.e. we
don't know about it), you may have to edit by hand. I think
simfactory attempts to run lscpu to determine some of these
parameters, but if it is not present 1 may be the default.</p>
<p>If you are part of a group, it may be beneficial to have your ini
file checked in to simafactory (after it is debugged and tested)
so that other members of your group have access to it. We can help
make that happen.<br>

<div dir="ltr">Hello,

<div>I am trying to run the static_tov simulation on my
university's cluster (<a

moz-do-not-send="true">CRC Notre Dame</a>). However, I got
this error when acquiring 48 cores:</div>

</div>
<div><span

</span></div>
<div>I am assuming this is due to the <i>#Source tree
management</i> module in the
Cactus/simfactory/mdb/machines/<host>.ini file. In my
case, the automatic *.ini file I got has these configuration:</div>

<div>However, the machine I use has 24 cores for each node, and
the number of threads for each core is 1. That means if I run
the simulation using 48 cores, I need 2 nodes.</div>
<div><br>
</div>
<div>Although I didn't get 2 hosts successfully(I got only 1), I
am wondering if I have to edit the <host>.ini file after
the command ./simfactory/bin/sim setup-silent by hand, for
example: num-threads=1, nodes=2? Or is there any other correct
way for getting more than 1 node? </div>
<div><br>
</div>
<div>I would be appreciate it if you could give me some ideas on
this problem.</div>
