Way to specify version of R on HPC with SSH connector?

[Aariq]

My university's HPC currently has a bug with R 4.1 +. I can get clustermq working on slurm by specifying module load R/4.0 in the SLURM template file. However, when I try to use the SSH connector, it's not clear to me how to specify this. I have module load R/4.0 in the template file, but that only affects which version of R the workers load. Is there a way to configure the top level process with the SSH connector?

You can provide your own SSH template to specify which version of R to use, or to load a module before calling R (use && to chain them together):

ssh -o "ExitOnForwardFailure yes" -f \
    -R {{ ctl_port }}:localhost:{{ local_port }} \
    -R {{ job_port }}:localhost:{{ fwd_port }} \
    {{ ssh_host }} \
    "module load R/4.0 && R --no-save --no-restore -e \
        'clustermq:::ssh_proxy(ctl={{ ctl_port }}, job={{ job_port }})' \
        > {{ ssh_log | /dev/null }} 2>&1"

So I would just supply the path to this template on my local machine with options(clustermq.template = "my_ssh_template.tmpl")?

Yes, exactly

I got it up and running! Knowing about that template helped me figure out how to specify a port as well. Thanks!
