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".
