A simple Java JNI implementation that gives high-accuracy per-thread CPU cycle information.

The native implementations are released to the public domain. This implementation has a dependency on the MIT-licensed com.wapmx.native.mx-native-loader but this can be removed

Includes native implementations for Linux and for Windows.

Important implementation note:

Windows - calls QueryThreadCycleTime, returns number of CPU cycles

Linux - calls clock_gettime passing CLOCK_THREAD_CPUTIME_ID, returns time in nanoseconds that this thread has spent executing on CPU

To rebuild the packaged native libraries, navigate to src/main/native and invoke:

Windows - win32/build.bat

Linux - linux/build.sh

TEMPORARY NOTE: the committed version of the win32 binaries are out of date and need to be rebuilt, but I do not have access to a Windows machine at present
