To use the SSM environment on Compute Canada clusters of the Alliance you will first (and only once) have to do the following little "setup". There is nothing to be done on our UQAM servers.

| You need to follow all of the instructions below! You cannot skip any parts! I strongly suggest to use copy->paste!!! There are dots and spaces that are easy to miss when typing the commands by hand. |

First a little "warning":
By default, the "prompt" (beginning of a command line) on Compute Canada clusters of the Alliance looks like this:
node n%
You first have the name of the login node, followed by the number of you command (which increases by 1 with each command you type), followed by the sign(!) '%'.
For example on narval1 (one of the login nodes on Narval) you might get:
narval1 1%
The '%' here is not a 'percent of setup done' but just a sign to mark the end of the prompt!

Use old cluster environment
On Beluga (only on Beluga), to use the old Beluga environment, create the file ~/.modulerc:

| cat > ~/.modulerc <<+ module-version StdEnv/2018.3 default + |
On Narval : Make sure you do NOT have the , to use the old Narval environment, create the following file ~/.modulerc !!!:

Then create the file ~/.profile:
On Beluga :

On Narval :

Use environment created by Michel Valin but using /scratch, which is often not working! When this environment is used and when /scratch is NOT working one will not be able to log on to Narval and simulations are not able to start.

Use environment avoiding /scratch. This environment should not be affected by a not working /scratch but is still in test phase. 1) Create a directory which you would like to make your default temporary directory. I suggest you use the default directory of your PI, for example: 2) Create a directory in your home called 'tmp':

which you will have to create.
Then you either log out and back in again or source the new .profiles.
