Finding Information About Your Computer
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.
Group computer reps can manage group entries in the department database and there's a hardware inventory and a space report too.
Storage Information
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/$USER/.conda
To find out how much storage you have available and what files/directories are taking up space, the following commands are useful. The first one shows how much space is used/available on each partition, and the second shows the size of everything in the current directory.
df -h
du -sh * | sort -hr
If you can't find any fiiles in /scratch/$USER/thom-fs-common you might need to authenticate with a password. You can do this if you are using key authentication with
ssh -oPubkeyauthentication=no localhost
| 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 | 2.3T | Backed up with snapshots - Theory RIG policy |
| /scratch/$USER/ifs-thom | Former UIS Mount - now located at /scratch/$USER/thom-fs/old-ifs-thom | 6144Gb | Read-only |
| /scratch/$USER/theory-fs | Chemistry network drive | ~50Gb per person | Backed up with snapshots - Theory RIG policy |
| cerebro:/filestore | Local RAID array | 36950Gb | Backed up with snapshots - Theory RIG policy |
Theory RIG backup policy
From https://www.ch.cam.ac.uk/computing/managed-linux-workstations-faq
- have a few backups taken over the last 24 hours
- then, about one backup per day for the previous week
- then, about one backup per week for the previous month
- then, about one backup per month for the previous few months
