=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.

[http://hobbit.ch.cam.ac.uk/xymon/workstations/workstationsThom/workstationsThomLinux/ Hobbit] may also have some useful information.

[https://www.ch.cam.ac.uk/computing/group-computer-representatives Group computer reps] can manage group entries in the department [https://chemdb.ch.cam.ac.uk/hotwire3/chemistry/ database] and there's a [https://apps.ch.cam.ac.uk/computer-reps/group-computers.php hardware inventory] and a [https://apps.ch.cam.ac.uk/space-management/space-report.php 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

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

=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
