LSDF_Online_Storage for HPC Cluster

The LSDF storage is permanently mounted on the login nodes and the data movers.

Both for interactive and for batch use, the environment variables $LSDF, $LSDFHOME and $LSDFPROJECTS are set.


Mount on the login nodes

Environment variables:
LSDFPROJECTS=/lsdf/kit/inst/projects
LSDFHOME=/lsdf/kit/inst/xy1234
LSDF=/lsdf

Limits:
Cpu time limit: 3600s
Virtual memory limit: 8-12GB

Batch Jobs

On the compute nodes, the LSDF usage is indicated to the batch system via "#SBATCH --constraint=LSDF".
