Run a massive builds on the worker nodes

# Run 'interactive' batch job using SLURM 'srun' command
# -p gw : 'gw' queue offering the longer walltime than the default 'gwdebug'
# --ntasks-per-node=48 : number of cores requested (1 node provides up to 48 cores)
# --time=48:0:0 : walltime (documentation says that the default walltime in 'gw' queue is 48h but not explicitly specified is set to 1h - To Be Checked)
# --pty /bin/bash : pseudoterminal
bash> srun -p gw --ntasks-per-node=48 --time=48:0:0 --pty /bin/bash |
Once resources are allocated, a new shell is being opened on the working node. A file system error is reported in most cases:
| Code Block |
|---|
bash: /afs/eufus.eu/user/g/g2<user>/.bashrc: Permission denied |
It means that the Kerberos token should be set/renewed, to allow access to the filesystem:
| Code Block |
|---|
bash> kinit; aklog |
Now .bashrc could be 'sourced' to enable user's startup settings:
| Code Block |
|---|
bash> source .bashrc |
Now EasyBuild can be used to build a software.

- Add
--parallel=48 to EB commands (on the working nodes EB doesn't recognise properly a number of available cores and runs sequentially - To Be Checked) - EB has built-in feature that allows to submit build to the batch system (see this link) - To Be Checked
