We move to RuSTRAC for obvious reasons. Feel free to try it
STRAC, a tools collection tailored to compare traces.
- java >= 14
We included a vectorized version of DTW, unfotunately, JAVA doesn't support vectorizaiton yet. It is an experimental feature for jdk 15.
You can avoid this feature changing the jdk target version, export JAVA_TARGET=11
, also you need to remove the vecctorized implementation
rm STRACAlign/src/main/java/strac/align/align/implementations/SIMDDTW.java
Use project Panama https://jdk.java.net/panama/ To run this project with the vectorized implementation, you will need a specific development build of OpenJDK, containing the OpenJDK jdk.incubator.vector module. You will need to build it from source.
Detailed build instructions are available at https://hg.openjdk.java.net/panama/dev/ in doc/building.md.
You will need a regular Java 11 installation, a Mercurial client, a usual build environment, and on Windows, Cygwin and the Microsoft Visual C++ Build Tools 2017.
In a shell (on Windows, in a Cygwin shell), run:
hg clone https://hg.openjdk.java.net/panama/dev/
cd dev
hg checkout vectorIntrinsics # the branch we need is vectorIntrinsics
bash configure --disable-warnings-as-errors
make images
If everything worked properly, the compiled JDK will be available at build//images/jdk (for example, the java tool is available at build//images/jdk/bin/java).
