Notes
To find out your OS version, run
lsb_release -a
To determine the RAM, run
head -1 /proc/meminfo
To find out core counts, run
cat /proc/cpuinfo
NB the number of 'processors' may be different from the number of cores owing to hyperthreading. The 'cpu cores' value is the one to take for single CPU machines.
Hobbit may also have some useful information.
Group computer reps can manage group entries in the department database and there's a hardware inventory and a space report too.
Storage
A common cause of running out of storage on your workstation is anaconda which puts stuff in /home. This can be safely moved to /scratch and a symbolic link.
cd $HOME mv .conda /scratch/$USER ln -s /scratch/$USER/.conda
| Name | Type | Amount | Notes |
|---|---|---|---|
| /home/$USER | local disk | ~50Gb per person (changed to ~100GB after upgrade to 20.04) | Backed up with snapshots - Theory RIG policy |
| /scratch/$USER | local disk | ~1Tb+ depending on computer | NOT BACKED UP |
| /scratch/$USER/thom-fs-nethome
/scratch/$USER/thom-fs-common |
Chemistry network drive | 526Gb | Backed up with snapshots - Theory RIG policy |
| /scratch/$USER/ifs-thom | UIS IFS mount | 6144Gb | Backed up with snapshots (24h+30d+12m)- avoid too much churn |
| /scratch/$USER/theory-fs | Chemistry network drive | ~50Gb per person | Backed up with snapshots - Theory RIG policy |
