Benchmarking is an essential element in evaluating the success of a hardware prototyping project. In the DEEP-ER project we use the JUBE benchmarking environment to assess the performance of the DEEP-ER system.

Benchmarking a computer system usually involves numerous tasks, involving several runs of different applications. Configuring, compiling, and running a benchmark suite on several platforms with the accompanied tasks of result verification and analysis needs a lot of administrative work and produces a lot of data, which has to be analysed and collected in a central database. Without a benchmarking environment all these steps have to be performed by hand.

For each benchmark application the benchmark data is written out in a certain format that enables the benchmarker to deduct the desired information. This data can be parsed by automatic pre- and post-processing scripts that draw information, and store it more densely for manual interpretation.

In the DEEP-ER project we use the JUBE benchmarking environment that is actively developed by the Jülich Supercomputing Centre.

JUBE provides a script based framework to easily create benchmark sets, run those sets on different computer systems and evaluate the results. Within the DEEP-ER project, the main focus lies on collecting benchmarking tests to compare

  • The different I/O approaches used in DEEP-ER.
  • The I/O performance in DEEP-ER with respect to production systems.

For this purpose, all DEEP-ER co-design applications are integrated into the JUBE benchmarking environment.

The version used in DEEP-ER is written in Python and is currently installed on the DEEP Cluster as well as on the DEEP-ER SDV. Installation of JUBE on the DEEP-ER Booster will follow.
