 On the NEC-machine only specific software to compile and run PALM is available (NEC Fortran compiler, NetCDF-, FFTW-, and MPI-libraries). Software modules provided by LUIS are not accessible. Following steps describe the PALM installation:
 
- 1. Login on the LUIS cluster system, create {{{~/palm/current_version}}} and checkout PALM from the svn-repository. You need to do that on the LUIS login-node, because svn is not installed on the BEC-Aurora.

Please install r4370 or later, because earlier versions are not well vectorized for the NEC and will show a very poor performance.

 * In case that two people or more likes to use the machine for longer production runs, we need to discuss with the LUIS administrators how to inlcude the specific Aurora ressources (vector engines) in the SLURM directives, which would be a requirement to submit batch jobs on the machine.
 * trunk/SCRIPTS also contains a configuration file for debugging ({{{.palm.config.aurora_debug}}}).
+* Currently, only the dynamical core of PALM is well vectorized for the NEC-Aurora. Further optimization for the advection routines and other PALM modules will follow soon (last update Jan 2020).
