-A few Python modules are already installed on the Peregrine cluster, however if you want to use a module that is not installed yet, you can install it for your own user account. The Peregrine cluster automatically will detect that you have that package installed in your personal directory (/home/username/) where your username is something like "p123456".

-In order to [[peregrine:software_environment:installation_of_extra_applications_or_libraries#r|install a package in R]], you have to start R in the cluster. This is done by loading the module R, starting R (by typing “R” in the terminal) and install the package as you normally install a package in R. After the installation you can quit R. The Peregrine cluster now will detect that you have this package installed when it is running a job which makes use of that particular package.+In order to [[habrok:software_environment:installation_of_extra_applications_or_libraries#r|install a package in R]], you have to start R in the cluster.

-Depending of the amount of resources that are requested for a job, it can take a while for a job to get started. Therefore, it might be useful to get a notification of when the job is started. It also is very helpful to know when a job is completed if you need the results of the job for further research. With the information of the begin and completion time of a job, a better estimation can be made for running another similar job. An email notification can be requested by adding the following lines to your job script: +Depending of the amount of resources that are requested for a job, it can take a while for a job to get started.

-These two lines send a mail to the email address provided in the script to notify when a job is started, has failed or finished. Alternatively you can also use the mail type ''ALL'' to be notified of even more status changes.

-The Peregrine cluster uses a priority queue. When you submit a lot of jobs, your priority decreases. This way, other users also get their share of the cluster.
