I don't know if the old behavior I observed (depended on!) is still the case or but it's worth mentioning.
In a cluster I used to manage that used a shared Matlab license server we discovered that the Matlab license server would only use one license per user per node. Thus, a node with many cores running multiple single core jobs for a single user would use fewer licenses according to the Matlab license server than Slurm had 'counted' if each running job used one license in Slurm. Because of this behavior I configured our scheduler to pack jobs onto nodes instead of spreading them across nodes to minimize the number of shared Matlab licenses our cluster consumed. – Trevor On Aug 24, 2016, at 3:23 PM, Raymond Norris <[email protected]<mailto:[email protected]>> wrote: Hi, We’re running 14.0.3.3-2. I’m comparing Slurm’s view of used licenses with that of FlexNet’s. Slurm shows 360 used, while FlexNet shows 80 used – a difference of 280. <image003.jpg> Aside from someone submitting a Slurm job with a license request that doesn’t actually use it, why would Slurm think there are more licenses used than Flex has checked out? Have others seen this? Thanks, Raymond
