3. Configuration Optimization Tool
The problem:
o Big Data technologies have
100s of tuneable parameters
o A knowledge gap is faced by
SMEs in configuring these
technologies
What does the tool do?
o Automatically runs
experiments on DIAs
o Returns recommended
configuration parameters for
Big Data technologies
3©DICE
Innovation:
o Automate DIA configuration
across release cycles
o Prior art focuses on manual
configuration
Impact & stakeholders:
o Reduce cost and time of
testing between releases
o Support operators of DIAs

1- Information
about the
experiment: budget,
config file, duration
of each experiment
2- Information
about the
configuration
parameters and
their options that
testers determine

7. Optimization Component (Matlab)
7©DICE
- This component select
the next configuration to
experiment considering
the current
measurements,
- This continues until
optimum configuration
located or experimental
budget finished.
The optimization overhead
is negligable comparing
with measurements
This componly relies on
rayality free MCR
component

This component runs the experiments and measures the
performance of the system under test, the data are flushed to
csv file and communicated with the optimization component
