This is a major release version of the Benchmarking Suite that introduces several changes and improvements with respect to the Benchmarking Suite 1.x versions.

In the Core library:

  • a complete refactoring of the code to improve the parameterization and modularization
  • introduction of benchmarking sessions

In the StdLib library:

  • for Benchmarks:
    • NEW CFD Benchmark
    • Updated Filebench and YCSB tools versions
  • for Cloud Providers:
    • NEW FIWARE FILAB connector
    • Updated Amazon EC2 to work with VPCs

The Cli and REST modules are completely new and the previous implmentation have been abandoned.
