Compiling software

Multithreading processes are not allowed on the interactive servers and may be killed (see Best practices on “cca”). However compiling can be achieved faster thanks to multithreading compiling, using make -jN with N the number of concurrent processes.

Therefore, in order to compile software or your own source code, the best way to achieve it is to use an computing resources interactive worker node (see Interactive Jobs for details).

You may want to specify the number of cores you will need. You can check the number of free CPUs using the htop command.
