Java/C Comparative Benchmarks

Versions

1.0.5 - Updated some of the Java benchmarks to build properly with the current version of the timing and profiling libraries.

1.0.4 - Updated makefiles to match the current CPoorMansTimingAndProfiling use of the traditional lib/ and include/ layout

1.0.3 - Modified the Parallelism tests to also measure task activation times

1.0.2 - Removed dependence on jcmdline from many of the benchmarks - Fixed minor though annoying bug in Parallelism-Benchmarks-J

1.0.1 - Minor cleanup and tweaking - A Makefile issue cleaned up in some of the benchmarks

1.0.0 - Initial Release

Overview

This is a collection of software benchmarks developed to compare the performance of Java with C on "identical" code. No language libraries were used in the timed parts of the tests to avoid implementation differences. Some of the benchmarks are also implemented in Python and Scala.

Benchmarks include:

  • Bit twiddling
  • Numerical computing
  • In-memory data structure creation and walking
  • Compute parallelism
  • Calling out from Java/Python/Jython to native libraries
  • Utilization of graphics processing units (GPU) from Java and C
