Last week we updated all CEP1 compute nodes (lcexxx
) to Ubuntu 10.04 LTS, the same OS as is used on the CEP2 cluster. That means that users will use the same version of packages on CEP1 and on CEP2. In case you encounter problems with your package, let us know. The move to the new OS also ended the subdivision in subclusters on CEP1.

25 Nov 2009: Some packages removed
Some time ago a new package LofIm was set up, that contains combined and interlinked builds of the packages:
- casacore
- casarest
- pyrap
- LOFAR offline software
- askapsoft (cimager)
The LofIm package is build daily (see lofim for some details). We have stopped building the individual subpackages separately, but the initialization scripts are still there.
To prevent users from activating outdated versions of these subpackages, I will remove the initialization scripts for these, today. All users that want to make use of one of the subpackages, will have to activate the entire LofIm package by typing 'use LofIm' on the command line, or by adding 'LofIm' to your $HOME/.mypackages file (assuming you are using our login scripts).
If a build of LofIm fails, you can revert to an earlier build; see the Wiki page for details.
Let me know of any mishaps or problems you encounter when using the LofIm package, so we can fix things asap, also on behalf of all other users..!
With kind regards,
Arno Schoenmakers
31 Oct 2009: New package LofIm
New package: LofIm, to replace casacore, pyrap, Lofar, casarest, askapsoft. See this page for more info.
