For now, single-local Chapel on Compute Canada's general purpose clusters (Cedar, Graham and Béluga) is installed in a non-central location and can be initialized with a script. For example, you can use <code>salloc</code> to test Chapel codes in serial: | |||

Installing multi-locale (distributed-memory) Chapel requires fine-tuning its launcher for the specific physical interconnect on | Installing multi-locale (distributed-memory) Chapel requires fine-tuning its launcher for the specific physical interconnect on a cluster. Since different Compute Canada clusters employ different physical interconnects, we do not have one multi-locale Chapel for all machines. Instead, multi-locale Chapel has been compiled in a separate directory as an experimental setup on each system. You can test this setup with the following Chapel code printing basic information about the nodes available inside your job: | ||
