---+ PALMA3 palma3 is the login node to a newer part of the !PALMA system. It has various queues for different purposes: * u0dawin: A queue for general purpose. It is usable for everyone, even without being a member of the groups that have submittet a proposal for !PALMA. It replaces the old !ZIVHPC cluster * k20gpu: Four nodes equipped with 3 K20 nVidia Tesla accelerators each * normal: 44 nodes with 32 Broadwell CPU cores each. (Not fully installed yet) * zivsmp: A SMP machine with 512 GB RAM. The old login node of !ZIVHPC. (At the moment still part of !ZIVHPC.) * phi: 2 Nodes with 4 Intel Xeon Phi accelerators each. (A part of !ZIVHPC at the moment). ---++ The batch system The batch system on PALMA3 is SLURM, but there is a wrapper for PBS installed, so most of your skripts should still be able to work. If you want to switch to SLURM, this document might help you: [[https://slurm.schedmd.com/rosetta.pdf]] When using PBS skript, there are some differences to PALMA: * The first line of the submit script has to be #!/bin/bash * The variable $PBS_O_WORKDIR will not be set. Instead you will start in the directory in which the script resides. * For using the "module add" command, you will have to source some scripts first: "source /etc/profile.d/modules.sh; source /etc/profile.d/modules_local.sh" ---+++ Running interactive jobs with SLURM Use for example the following command: <verbatim>srun -p u0dawin -N 1 --ntasks-per-node=8 --pty bash</verbatim> -- %USERSIG{HolgerAngenent - 2016-08-22}% ---++ Comments %COMMENT%
