How to run

With JAVA_HOME and PATH pointing to a Panama vectorIntrinsics build, run:

./mvnw package && java -jar target/bench.jar

Without having a local Panama vectorIntrinsics build, run:

./ci.sh

This will shallow-clone the GitHub mirror of the Panama vectorIntrinsics branch, build the JDK and execute the benchmarks using it. Make sure your system fulfills the OpenJDK build requirements. See the section "Clean Ubuntu Setup" below for a clean Ubuntu setup. The space requirements for such a cloned and fully built JDK is ~5.6GB, which will reside inside of the panama-vector directory. In addition, the hsdis utility library is built and installed into the JDK's lib directory.

Clean Ubuntu Setup (tested on Ubuntu 22.10)

sudo apt install -y libasound2-dev \
                    libfontconfig1-dev \
                    libcups2-dev \
                    libx11-dev \
                    libxext-dev \
                    libxrender-dev \
                    libxrandr-dev \
                    libxtst-dev \
                    libxt-dev \
                    git \
                    zip \
                    unzip \
                    automake \
                    autoconf \
                    build-essential \
                    openjdk-19-jdk-headless

Seeing the disassembly

In order to see the x86 code generated by the JIT compiler for all methods, run:

java --add-modules jdk.incubator.vector -XX:+UnlockDiagnosticVMOptions -XX:CompileCommand=print,*Matrix*.* -cp target/bench.jar bench.C2

The x86 code is then printed to stdout. This requires the hsdis utility library available in the $JAVA_HOME/lib directory, as is provided by ./ci.sh.
