New Opterox-Login
Server is zeon.physik.uni-due.de, home directories are the same.
Queueing system = Slurm
sinfoshows overall load and available queues (partitions). The default one is marked with*.squeueshows running jobs.- simplest submission:
sbatch -nn script-name scanceljob-id kills job.
Intel oneAPI
Intel compilers, MKL and MPI are installed, must be selected via the module system:
module use /opt/intel/oneapi/modulefiles (unless you include that directory in your MODULEPATH)
module availlists the installed modules, relevant are:- compiler/latest →
ifort,icpc,icc, ... - mpi/latest →
mpirun,mpiifort,mpiicpc,mpiicc, ... - mkl/latest
- compiler/latest →
module load... loads a module.
Inside a shell script (bash), you have to do shopt -s expand_aliases before being able to use the module command.
Pitfalls
ifort/mpiifort: When compiling with-i8, you also have to link with-i8(cf. also manual).
OpenMPI
- The setting
export OMPI_MCA_pml=ucxis necessary to prevent a "failed OFI Libfabric library call".
