+<P>SLURM can be used to provide resource management for systems with the

+SLURM sets an OFFLOAD_DEVICES environment variable, which controls the

+automatic offload.
+(This is very similar to how the CUDA_VISIBLE_DEVICES environment variable is
+used to control which GPUs can be used by CUDA&trade; software.)
+If no MICs are reserved via GRES, the OFFLOAD_DEVICES variable is set to
+-1. This causes the code to ignore the offload directives and run MKL
+routines on the CPU. The code will still run but only on the CPU. This
+also gives a somewhat cryptic warning:</P>
+<pre>offload warning: OFFLOAD_DEVICES device number -1 does not correspond
+to a physical device</pre>
+<P>The offloading is automatically scaled to all the devices, (e.g. if
+--gres=mic:2 is defined) then all offloads use two MICs unless
