You can put up to 500 MB of data under your home. There is no limit for the number of files. You can check your current quota with the command:
quota
For more information about the command see: quota
data space:
The data space is shared by everybody using the same filesystem (main base directory). You can check the usage of any mounted filesystem with the command 'du'. For example:
du -h /filesystem
If you see the usage of a filesystem is greater than 95% you are welcome to let me (winger.katja@uqam.ca) know!
memory:
The memory is shared by all users using the same server. This is why we ask you not to use more than 64 GB in total at any given time. You can check the available memory with the command:
free
You can check and monitor the usage of your own processes with the command 'top'. For example:
top -u ${USER} # You can use the command as is. The variable 'USER' is defined by default and set to your username.
Once 'top' opened press the key 'M' (capital) to sort the processes according to memory usage instead of CPU usage. Look the the column 'RES'.
CPU power:
The CPU power is shared by all users using the same server. To see how many cores are available on a given server execute the command:
lscpu
Look at the line "Core(s) per socket". To see how many CPUs are currently in use you can also use the command 'top':
top
Look the the column '%CPU'.
