Accelerate SCRATCH storage using the Smart Burst Buffer (SBB) technology. A specific Burst Buffer process is launched and Burst Buffer resources (CPUs, memory, flash storage) are allocated on an SBB storage node for acceleration (I/O caching) of SCRATCH data operations. The SBB profile file `/lscratch/$PBS_JOBID/sbb.sh` is created on the first allocated node of job. For SCRATCH acceleration, the SBB profile file has to be sourced into the shell environment - provided environment variables have to be defined in the process environment.

Modified data are written asynchronously to backend (Lustre) filesystem, writes might be proceeded after job termination.
Barbora cluster provides two SBB storage nodes equipped with NVMe disks. Each storage node contains ten 3.2TB NVMe disks and provides net aggregated capacity of 29.1TiB. Acceleration uses RDMA network i.e. InfiniBand is used for data transfers.
