MI computing servers

Name      # cores   Proc. type   Speed     Memory   Date purc.
————————————————————————–

mi-loke      4*8   Intel Xeon       2.7GHz     384GB   2013.09.05

Is running linux the operating system.

Login

From a VPN connection, you may use ‘ssh mi-loke.klientdrift.uib.no’.

Be nice policy

Both MATLAB and R have functionality for starting “cloning” processes.

  • Please do not start more than 32 parallel processes (per user/group) on each machine. By “group” it is meant ABM, Pure Math and Statistics.
  • Learn about the “top” command in linux to locate a machine with low current load.

It is the “load average: 0.00, 0.01, 0.05” on the first line of the output from top that shows the current load of the machine (a load of 64 is acceptable for these machines).

To find out which other members in a group that is using the machine please use the command “finger”.

web-cache

Wednesday, August 15th, 2007

Connecting to the wireless network

Tuesday, August 14th, 2007

[Update:  The article below was written in 2007.  While it is hopefully still correct, it is now perhaps better to use the “eduroam” wireless network instead, see this article.  SAS]

The university’s wireless net has SSID UiB. Once you have conncted to the wireless net and opened a browser, a dialog box will pop up. Fill in username and password, and you should be able to browse the net, use ssh, print etc. (See separate post on printing.) WARNING: Guests with kurskonto have username of the form username@kurs

You may want (or need) to connect to the VPN (“virtual private network”). Here the difficult part is that your username is user@ansatt.uib.no for employees, and something analogous for students. Currently the gateway vpn-ansatt.uib.no works for employees  (vpn-student.uib.no for students).

Printing from your PC

Tuesday, August 14th, 2007

It appears that there are at least three ways to set up printing. Two of them require VPN to be set up, the third works when you are connected to the wireless net without having set up VPN. One of them is “the Microsoft way” and the other two more Unix-like. Remember to check that the papersize is correct after having set up the printer!

The Studentwiki provides step-by-step instructions for setting up printing on Ubuntu machines.

Mounting remote filesystems

Thursday, August 2nd, 2007

The command sshfs mounts a remote filesystem. For example the command

sshfs alfred:/People/www/mbr085/ www

mounts the filesystem containing my personal web-pages into the directory www. (For this to work an empty directory called www should already exist.)
