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
