 Slurm supports the ability to define and schedule arbitrary resources - Generic RESources (GRES) in Slurm's terminology. We use GRES for scheduling/allocating GPGPUs and FPGAs.
 
 !!! warning
 Use only allocated GPGPUs and FPGAs. Resource separation is not enforced. If you use non-allocated resources, you can observe strange behaviour and get into troubles.
