<p class="MsoNormal">I am starting to use a hpc cluster of my
university, but I am very green on parallel computation.</p>
<p class="MsoNormal">I have made a first test (test #1) on a very
small-scale simulation (relaxation of a GO sheet with 19 atoms,
with respect to the gamma point). The calculation took 3m20s to
run on 1 proc on my personal computer. On the cluster with 4 proc
and default parallel options, it took 1m5s, and on 8 proc it took
44s. This seems like a reasonable behavior, and at least shows
that raising the number of procs does reduce computation time in
this case (with obvious limitations if too many procs for the
job).</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">However I tried with another test, a bit bigger
(test #2). This example is a scf calculation with 120 atoms (still
with respect to the gamma point). In this case, the
parallelization brings absolutely no improvement. In fact,
although the <i>outfile</i> confirms that the code is running on
N procs, it has similar performances as if it was running on 1
proc (sometimes even worse actually, but probably not in a
significant manner, as the times are fluctuating a bit from 1 run
to another)</p>
<p class="MsoNormal">I tried to run this same input file on my
personal computer both on 1 and 2 cores. Turns out that it takes
10376s to run 10 iterations on 1 core, while it takes 6777s on two
cores, so it seems that the parallelization is doing ok on my
computer.</p>
<p class="MsoNormal">I have tried to run with different number of
cores on the hpc, and different parallelization options (like for
instance –nb 4), but nothing seems to improve the time</p>
<p class="MsoNormal"> <br>
</p>
<p class="MsoNormal">Basically, I am stuck with those 2 seemingly
conflicting facts:</p>
<ul>
<li><span
style="font-family:Symbol;mso-fareast-font-family:Symbol;mso-bidi-font-family:Symbol"><span
style="mso-list:Ignore"><span style="font:7.0pt "Times
New Roman""></span></span></span>Parallelization
seems to have no particular problem on the hpc cluster because
test #1 gives good results</li>
<li>Parallelization seems to have no particular problem with the
particular input file #2 because it seems to scale reasonably
with proc number on my individual computer</li>
</ul>
<p> </p>
<p class="MsoNormal">However, combining both and running this file
in parallel on the hpc cluster ends up not working correctly…</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I included below the input file and output file
of test #2. I also included as well as the slurm script that I use
to submit the calculation to the job manager, in case it helps
(test2.scf.slurm.txt)</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Any suggestion on what is going wrong would be
very welcome.</p>
