Simple Microbenchmarks for ND4J utilizing the JMH
mvn clean package
java -jar target/benchmarks.jar
For a quick run, e.g. just the same Matrix Size progression as used in the Neanderthal benchmarks, run like this:
java -jar target/benchmarks.jar -f2 -i10 -wi 2 Neanderthal
Since ND4J supports multiple blas libraries, you have to specify which one you actually want to use. For my own benchmarks I've been using MKL.
