	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.

	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
