| + | ==== Using interactive jobs ==== | ||
| + | |||
| + | |||
| + | First, allocate a HEP node: | ||
| + | |||
| + | <code bash> | ||
| + | salloc -N 1 -p hepd -A condo -t 00:30:00 | ||
| + | </ | ||
| + | |||
| + | This allocates it for 30 min, but you can allocate it up to 7 days. | ||
| + | You cam also allocate it on bebob: | ||
| + | |||
| + | <code bash> | ||
| + | salloc -N 1 -p bdwall --account=ATLAS-HEP-group -t 00:30:00 | ||
| + | </ | ||
| + | |||
| + | This does not login you! | ||
| + | Check what node did you allocate | ||
| + | |||
| + | <code bash> | ||
| + | squeue -u user | ||
| + | </ | ||
| + | |||
| + | |||
| + | Now you know the node. Then login to bebob (first!) and then ssh to this node. | ||
| + | |||
| + | Another method is to use | ||
| + | |||
| + | <code bash> | ||
| + | srun --pty -p bdwall | ||
| + | </ | ||
| + | |||
| + | |||
| + | === Running long interactive jobs === | ||
| + | |||
| + | See more description in: https:// | ||
| + | |||
| + | You should be able to do for example: | ||
| + | |||
| + | < | ||
| + | -ssh bebop | ||
| + | -screen | ||
| + | -salloc -N 1 -p hepd -A condo -t 96:00:00 | ||
| + | -ssh < | ||
| + | -Work on interactive job for x amount of time... | ||
| + | -Disconnect from screen (different than exit, see the documentation) | ||
| + | -Logout | ||
| + | </ | ||
| + | |||
| + | < | ||
| + | -Login to the same login node screen was started on | ||
| + | -screen -ls | ||
| + | -Connect to screen session | ||
| + | -Continue where you left off (if they allocation is still active) | ||
| + | </ | ||
| + | |||

| + | One can also setup cvmf on any LCRC nodes as this: | ||
| + | < | ||
| + | source / | ||
| + | </ | ||
| + | |||
| + | Then check: | ||
| + | < | ||
| + | ls /cvmfs/ | ||
| + | </ | ||
| + | |||
| + | You will see the mounted directory (SL7): | ||
| + | < | ||
| + | atlas-condb.cern.ch/ | ||
| + | atlas-nightlies.cern.ch/ | ||
| + | </ | ||
