Correct, NNU would allow a named user to run unlimited MATLAB on up to two 
machines concurrently, so I could see how things might get out of sync.  As 
Stack pointed out, this is for MDCS which, similar to MATLAB concurrent, 
requires a single license for a single running instances (i.e. 32 Workers 
running on 32 cores requires 32 licenses).

I ran

   % scontrol reconfig

And restarted Flex, but to no avail.  They are still out of sync.

Has anyone else seen this?

Thanks,
Raymond

I manage a bunch of Matlab licenses. That is as-designed for NNU licenses. You 
get 2 hosts per license and it doesn't matter if you start up 2 jobs on 2 
systems, or 3 dozen on two systems. However, start up a 3rd and FlexLM *should* 
smack it down.

I wish Mathworks had a better integration with SLURM for this kind of license 
usage, but that is another topic.

The issue that Raymond is having looks like it is specific to MDCS/SLURM.

Normally, I would suggest restarting the FlexLM service. I have seen licenses 
"stick" many times. FlexLM thinks the license is in use when it isn't.

However, this is clearly something in SLURM from the output Raymond posted and 
I am afraid I have no suggestions on that one. Especially since Raymond and Sam 
would be the ones I would go to for help if _I_ had this issue! :-)

Sorry, Raymond. :-/

Good luck!
