= How can I use the old environments ? = | |||
If you have an existing workflow and want to continue to use the same software versions you are using now, simply add <code>module load StdEnv/2018.3</code> or <code>module load StdEnv/2016.4</code> to your jobscript before loading any other modules. | |||
= Will old environments go away ? = | |||
No, they ''will not go away''. They and all the software dependent on them will remain available! However, Compute Canada staff will no longer install anything into the old environemnts. | |||
= Which environment should I use ? = | |||
If you are starting a new project, or if you want to use a newer version of some software, you should use <tt>StdEnv/2020</tt>. Today you can do this by adding <code>module load StdEnv/2020</code> to your job script. As of April 1, it will be the default and the line will be unnecessary (though not a problem). | |||
