JVM comparaison

Compare the energy consumption of multiple versions of Java virtual machine based on SDKman JVM database

Tools

Building images

The script build_images.sh is used to generate docker images, each one represent a jvm version

• The file jvms.sh is used to configure the images
• The script will take only the uncommented lines into consediration
• The name of the generated docker images is following this syntax user/jvm:jvm-version

Measuring the energy

We do it by launching the script testbed.sh

This script will execute each line in the benchmarks file using all the jvms presentend in the jvm file and report the results in a report_file.logs resutls directory.

Later use the notebook all-jvms.ipynb to parse the report files

Measuring the evolution of power consumption

Same as testbed.sh the scrip recordpower.sh will execute all the benchmarks using the avialable jvms and record the powers into the powers/rapl

Use the notebook parse_powers.ipynb to parse the report files

Measuring the evolution of threads

Same as testbed.sh the scrip recordthreads.sh will execute all the benchmarks using the avialable jvms and record the evolution of threads into the records/benchmarkname

Use the notebook parse_records.ipynb to parse the report files

How to use

1. Select the Jvms that you want to use in the file jvms.sh, and then uncomment them
2. Build the docker images using the script build_images.sh
3. Select the benchmark that you want to test and put them in benchmarks/benchmarks.sh (or just uncomment them if they already exist)
4. Launch the tests using testbed.sh

Results

They will be found in the subfolder `benchmakrs/results
