====== MD-Workbench ======


This MPI parallel benchmark mimics the concurrent access to typically small objects.
It comes with the following features: 
  * deterministic access pattern mimicking interactive users or producer/consumer queues;
  * configurable working set size to fit into a cache of a given size or exceed it;
  * performance regression testing by preserving the working set between runs;
  * support for various storage backends (POSIX, MPI-IO, S3, MongoDB, PostgreSQL), and
  * report of throughput and latency statistics including timing individual I/O operations.

It therewith overcomes certain limitations of HPC metadata benchmarks and provides additional quantifiable measures.
