Dear Axel,

Thank you for the warm welcome and your detailed reply! While I am quite ne=
w to PIC codes, I have done scientific computing in the past and I now work=
 on laser-matter interaction at ELI-NP [1], where we are currently evaluati=
ng the possibility of using PIConGPU instead of EPOCH. In fact, my previous=
 question about OS/software stack was because I want to install a developme=
nt version of PIConGPU on my personal laptop [2] for some benchmarks agains=
t EPOCH and for playing around with the code.

On a separate note, one of my colleagues managed to install PIConGPU on a c=
luster, but he told me all the examples he could find in the docs refer to =
the PBS batch system, while the batch system on this particular cluster is =
Slurm. Are you aware of any examples of using PIConGPU with Slurm?
Thanks,

Andrei
