These benchmarks can take a very long time to complete, and for some tests utilize almost 100% of all CPUs.

Make sure we are running with the right JDK for Project Loom 
 $ "${JAVA_HOME}/bin/java" -version
 openjdk version "18-loom" 2022-03-15
 OpenJDK Runtime Environment (build 18-loom+2-74)
 OpenJDK 64-Bit Server VM (build 18-loom+2-74, mixed mode, sharing)
Make sure the laboratory has been compiled and installed for benchmarking. 
 $ cd laboratory
 $ mvn clean install
Run the benchmarks. 
 $ cd benchmarks
 $ mvn clean verify
 $ "${JAVA_HOME}/bin/java" -jar target/benchmarks.jar PrimeNumbers
 
 # Run complete. Total time: 01:44:07

 REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
 why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
 experiments, perform baseline and negative tests that provide experimental control, make sure
 the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
 Do not assume the numbers tell you what you want them to tell.
