First, you should debug the code locally to ensure it runs smoothly. Also, make sure that all required custom functions are included in the directory you plan to upload.

Secondly, download Globus for transferring code and data.

Third, establish a connection with cedar using the built-in Command Prompt in Windows.

1 2	ssh -Y username@cedar.computecanada.ca password

Create an executable file. First, navigate to the directory where the starting code for execution is located using the "cd" command.

Below is the template for the executable file. Prepare it in advance, and after creation, simply copy and paste it in. To save, use Ctrl+O, then Enter, and then Ctrl+X.

After successfully submitting the job, you can check its status at any time using the command "sq". Once the job has completed, the system won't provide any notifications, so it's important to keep an eye on its status.

Use scancel with the job ID to cancel a job:

1	$ scancel <jobid>

1 2	/Check the running status./ $ diskusage_report

When running on CC, never use absolute paths; always use relative paths.

The CC platform has a maximum file limit of 500K, so it's important to use resources efficiently and reduce the number of files during runtime.

1 2	% An absolute path /project/usernumber/username/Mat/SPEI/input/prec/prec_192404.tif

CC is a UNIX system and cannot directly run .EXE files. To run an .EXE file on CC, you first need to check if Wine is installed on CC. You can do this by typing 'wine' in the Command Prompt. If it returns the following, it means Wine is already installed.

wine
Usage: wine PROGRAM [ARGUMENTS...]   Run the specified program
       wine --help                   Display this help and exit
       wine --version                Output version information and exit
