Questions about using Alice
See: Load modules
Contact helpdesk@alice.leidenuniv.nl. Since software you need may also be useful to other ALICE users we will install most packages in the module repository for you. Please expect a little delay time after being honoured the central install as sometimes the install process can be lengthy and we have to make sure it is not clashing with other already installed packages.
Questions about Files and Sharing
You have been entered in a specific UNIX group. This group has the name of your institute and you can share files with all your ALICE institute colleagues by running the Unix change mod. utility: chmod g+r on files and chmod g+x on directories.
Make sure that you use the data share, which is available at /data, instead of your home directory. See also: Data Storage
Your data can be stored a limited amount of time. ALICE is not meant to be a storage facility and thus you will require other facilities to store and backup your data. You will be contacted if you have old data that is in the way of new users requirements. Disk space is limited so be a gentle user.
