<p>Hello,</p>
<p>I am new to Flash (I have just recently installed it), and I am
having some problems when running the LaserSlab example case in
parallel.</p>
<p>I have installed openmpi-4.0.5, hypre-2.12.0, hdf5-1.10.7, and
FLASH4.6.2. When I run the Sedov example using just</p>
<p><i>./setup -auto Sedov</i></p>
<p><i>mpirun -np [number of cores] flash4</i></p>
<p>It runs perfectly. However, when I do the same with the LaserSlab
example:</p>
<p><i>./setup -auto LaserSlab -2d +cylindrical +hdf5typeio -nxb=16
-nyb=16 species=cham,targ +mtmmmt +laser +uhd3t +mgd
mgd_meshgroups=6 -parfile=example.par</i></p>
<p><i>mpirun -np [number of cores] flash4</i></p>
<p>The code starts running, but freezes after <i>'Initial dt
verified'</i>.</p>
<p>Strangely enough, when the same setup command is run for
LaserSlab, but instead of running in parallel, FLASH is called to
operate in serial mode (./flash4), the code works without any
problems (it just takes a much longer time, obviously).</p>
<p>From what I have gathered, this seems to be a problem with the
hdf5 I/O, but I have been unable to solve it, and I don't know
what might be happening. Any thoughts about how to solve this?</p>
<p>Thanks everyone,</p>
<p>Gabriel Perez<br>
