==== TU/e cluster - How to use (by Vincent Huijgen) ====
\\
The BSR server namespace is: **bsr01.win.tue.nl**

The available resources are:

    * 2 processors
    * 20 cpu-cores
    * 384 GB memory
    * 384 GB swap
    * 482 GB in /home
    * 24 TB in /data

**Linux accounts** use the space in **/home**. They can get space in /data on request.

There are no disk-quota imposed.

The **database server mysql** uses the space in **/data**. This is a common space for all database accounts .

There is **NO backup for /home and /data**.

There is **protection against disk failure**, so that one disk may fail without losing data.

**Commands** to list resource usage:

<fc #ff0000>top</fc>
  processor and memory usage

<fc #ff0000>df -h</fc>
  Disk usage system-wide, for each filesystem: size, used, available

<fc #ff0000>du -sh $HOME</fc>
  Disk usage of your homedirectory with a convenient unit

<fc #ff0000>du -a $HOME</fc>
  Disk usage of all your files and directories in KB

Here are some commands to list all installed software packages. To scroll in long lines, use left/right arrows with the suggested less -S . For case-independent searching, we also recommend -i for less.

 <fc #ff0000>dpkg-query -l | less -iS</fc>
    The standard format, very wide

 <fc #ff0000>dpkg-query -W -f='${Package;-30}${binary:Summary}\n' | less -iS</fc>
    Name and summary only, easier for browsing and searching

 <fc #ff0000>dpkg-query -W -f='${Package;-30}${Version;-25}${binary:Summary}\n' | less -iS</fc>
    If the version is important

For more advance queries, use aptitude or the Ubuntu web pages.


**Availability:** There are currently no formal procedure to announce reboots or other interruptions in the availability.
