I agree that this is a common issue.  We see it both when people use batch 
schedulers as well as when people use Docker containers.  I don't have enough 
experience with batch schedulers to verify that NCPUS is commonly set.  I would 
encourage people to also look at what Docker uses.  

After a quick (two minute) web search I couldn't find the answer, but I suspect 
that one exists.  I've raised a question on Stack Overflow here:
