<p>Hello,</p>
<p>the script you attached has unfortunately been stripped off by
the antispam/antivirus system of my mail service. However, I can
see from the output that you are using "rsync" to copy files back
and forward, my guess is that you're not copying all the files.</p>
<p>The computing center administrator often recommends to use
baroque scripts that data, and sometimes even the executables,
back and forward. My recommendation is to set "outdir" to the fast
scratch space, but run the codes directly from the permanent
"work" or "home" space, thus avoiding the need to copy.</p>
<p>hth</p>

<p>Hello,</p>
<p>I don't know which guide you are following, but there is
not "fileps" variable in the inputpp namelist of epsilon.x</p>
<p>If you cannot find the output files, it may depend on the
code failing or on your script being wrong, which I cannot
know because you did not provide any od those.</p>

<div>Including noinv = .true. in my input file resulted
in a successful simulation run for my epsilon.x
