LLNL hires-timers

This is the llnl-hires-timers library, a library to support platform-specific high-resolution timers by a platform-independent c function-call: get_time_ns().

At compile time the best available timer at your platform will be selected and the platform-specific call to get the best timer will be used to return the timer value in nanoseconds.

Building

To build, you need to use cmake. We recommend that you build out of source. That is, you should make a directory to build in first.

r build
uild
e ..

Usage

You can use llnl-hires-timers by including hires-timers.h and calling the following function:

ng_t get_time_ns();

timing_t is defined as:

def unsigned long long timing_t;

At compile-time you should link (static or dynamic) against libhires-timers with -lhires-timers.
