When a job gets suspended and evicted it's memory requirements adjusted by the actual values measured during it's execution?

Yes.

 

For example:

1. I job with "request_memory = 500" is being submitted.

2. The job gets assigned to a node, starts running.

3. It allocates 2000MB.

4. The job gets suspended and evicted (reason does not really matter in this example)

5a. Job gets resubmitted to another node with memory requirement of 500MB (as requested by the user)

5b. Job gets resubmitted to another node with memory requirement of 2000MB (as measured during previous execution)

So which one is it 5a or 5b?

5b. Unless you do something specific to prevent it, but it doesn't sound like you are messing with the ImageSize _expression_ that gets generated when you use request_memory to set the memory expectation.
