I attempt to optimize resource allocations for nf-core/ampliseq. I am unsure though how multiple labels behave. For example, do I overwrite the memory allocation of

process_low

with that of

process_mem_3gb

, i.e. by the label sequence?

process XYZ {
    label 'process_low'
    label 'process_mem_3gb'
    [...]
}

The docs do not seem to consider this case, what would definetly take priority over the label is a withName selector, I guess it depends on how many

mem_3gb

processes you have

hm ok thanks. I asked because I didnt find it in the docs.

My assumption would be that the labels are applied in the order they are assigned to the process (3gb should overwrite low) but I am not sure if I ever tested that

This is what I did with proteinfamilies: https://github.com/nf-core/proteinfamilies/blob/dev/conf/test.config

I have confirmed, as far as I see, that multiple labels overwrite each other in sequence, as expected.
