 +
 +==== Status: ====
 +
 +All nodes are up and accessible via ssh.
 +
 +===== First Login: =====
 +
 +Login on the login node with the following command:
 +
 +<​code>​
 +ssh -l <​username>​ ssh.hca.bsc.es
 +</​code>​
 +
 +From the login node you can login to a computational node:
 +
 +<​code>​
 +ssh arndale-1
 +</​code>​
 +
 +Only a few computational nodes allow to login in (usually the computational node number one). The purpose of these nodes is to compile and run interactive jobs.
 +
 +Or submit jobs using SLURM resource management. Here an example of SLURM script:
 +
 +<​code>​
 +#!/bin/sh
 +#SBATCH -w $NODES
 +#SBATCH --ntasks=$($N_CORESx$N_NODES)
 +#SBATCH --cpus-per-task=1
 +#SBATCH -p $PARTITION
 +#SBATCH --job-name="​template"​
 +#SBATCH --error=err/​template-%j.err
 +#SBATCH --output=out/​template-%j.out
 +
 +JOBDIR=$HOME/​path/​to/​binaries
 +
 +cd $JOBDIR
 +mpirun ./$PROG
 +</​code>​
 +
 +You can get information about available partitions using //​sinfo// ​    ​command.
 +
 +===== Security policy: =====
 +
 +    * It is strongly suggested to change your password [[https://​chpasswd.hca.bsc.es/​|here]].
 +    * If a IUG member has multiple persons working on the prototype, please ask us additional accounts. We strongly deprecate account sharing.
 +
 +===== Contacts: =====
 +
 +The team of system administrators of Mont-Blanc is available to assist you in more detailed configuration. Do not hesitate to contact us at [[mailto:​hca.sysadmin@bsc.es|hca.sysadmin@bsc.es]].
