Hello,
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.
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
/./setup -auto Sedov/
/mpirun -np [number of cores] flash4/
It runs perfectly. However, when I do the same with the LaserSlab example:
/./setup -auto LaserSlab -2d +cylindrical +hdf5typeio -nxb=16 -nyb=16
species=cham,targ +mtmmmt +laser +uhd3t +mgd mgd_meshgroups=6
-parfile=example.par/
/mpirun -np [number of cores] flash4/
The code starts running, but freezes after /'Initial dt verified'/.
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).
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?
Thanks everyone,
Gabriel Perez
