Comments:

  • Benchmark has been re-written to use Gradle and download jars from Maven Central
  • Benchmark run by Anders Peterson
  • Most complete benchmark yet! All libraries up to size 10000 and took two months to run.

Summary Results

The following results are a weighted sum across all operations within each matrix size. Operations which take longer will have more weight. If a library could not finish an operation then its score is set to zero.

NOT The weight is computed from the amount of time the fastest library takes to complete. Which is why the results change a bit from Java to Java + Native.

Pure Java Summary Results

Mixed Java and Native Summary Results

Pure Java Libraries

These results show the performance of libraries that have code written entirely in Java.

Java: Basic Operation Results

Java: Solving Linear Systems

Java: Matrix Decompositions

Mixed Java and Native Libraries

These results show the performance of libraries that either use pure Java or calls to native libraries.
