Helpers
-------
A collection of C++ utility classes useful for benchmarking:
- helpers.hpp some tracing and debugging macros
- string_helpers.hpp a few string convenience functions
- Properties.hpp C++ implementation of java.util.Properties
- hrt_utils.h high-resolution time measurement utilities
- hrt_stopwatch.h high-resolution time stopwatch utility
- hrt_gstopwatch.h global (=singleton) high-resolution time stopwatch
- HrtStopwatch.java Java high-resolution time stopwatch utility
- HrtProfiler.java simple utility for manual Java code instrumentation
How to build:
-------------
0) Required: [g]make, JDK, C/C++ compiler
1) Edit the file ../env.properties
Configure the properties: JAVA_INCLUDEOPT0, JAVA_INCLUDEOPT1
2) Edit the file ./src/utils/Makefile
Uncomment/configure macro:
Linux, or for best clock resolution:
TDEFINES = \
-DHRT_REALTIME_METHOD=HRT_USE_CLOCK_GETTIME \
-DHRT_CPUTIME_METHOD=HRT_USE_CLOCK_GETTIME \
Generic Unix, MacOS X:
TDEFINES = \
-DHRT_REALTIME_METHOD=HRT_USE_GETTIMEOFDAY \
-DHRT_CPUTIME_METHOD=HRT_USE_GETRUSAGE \
LDLIBS = -lrt
3) Build the library
Run once:
$ make dep
Build either optimized or debug objects:
$ make opt
$ make dbg
4) Run tests (optional)
$ make check
or
$ cd src/utils/
$ make run.Properties_test
$ make run.hrt_utils_test
$ make run.hrt_stopwatch_test
$ make run.HrtStopwatchTest
