Hi,
I would like to execute some performance test with Boost.Build. Is there a way to force the execution of the tests without building the executables?
You should be able to do this:
exe hello : hello.cpp ; run-output hello.output : hello ; time hello.time : hello.output ;
The first metatarget just builds exe, as usual. The second runs the executable (capturing the output). The third records the time spend to run the executed.
You might need to 'import testing ; ' on top.
Are there some examples of performance tests for some Boost libraries?
I am not aware of such.
Hope this helps,
Thanks for the hint. I didn't know run-output and time. This allows me to get the time but in order to get again the time I need to force to build all with -a. $ bjam -q perf ...patience... ...found 2444 targets... ...updating 5 targets... gcc.archive /sandbox/stm/branches/vbe/libs/stm/build/bin/gcc-3.4.4/debug/link-st atic/threading-multi/libboost_STM.a gcc.link bin/gcc-3.4.4/debug/threading-multi/perf_counter.exe testing.capture-output bin/gcc-3.4.4/debug/threading-multi/perf_counter.run testing.time bin/gcc-3.4.4/debug/threading-multi/perf_counter.time user: [perf_counter.run] 0.106000 system: [perf_counter.run] 0.122000 ...updated 5 targets... $ bjam -q perf ...patience... ...found 2444 targets... $ bjam -a perf ...patience... ...found 2444 targets... ...updating 15 targets... gcc.compile.c++ bin/gcc-3.4.4/debug/threading-multi/counter.o gcc.compile.c++ /sandbox/stm/branches/vbe/libs/stm/build/bin/gcc-3.4.4/debug/lin k-static/threading-multi/bloom_filter.o gcc.compile.c++ /sandbox/stm/branches/vbe/libs/stm/build/bin/gcc-3.4.4/debug/lin k-static/threading-multi/contention_manager.o gcc.compile.c++ /sandbox/stm/branches/vbe/libs/stm/build/bin/gcc-3.4.4/debug/lin k-static/threading-multi/transaction.o gcc.compile.c++ /sandbox/stm/branches/vbe/libs/stm/build/bin/gcc-3.4.4/debug/lin k-static/threading-multi/except_and_back_off_on_abort_notice_cm.o gcc.archive /sandbox/stm/branches/vbe/libs/stm/build/bin/gcc-3.4.4/debug/link-st atic/threading-multi/libboost_STM.a gcc.compile.c++ /boost_1_39_0/bin.v2/libs/thread/build/gcc-3.4.4/debug/link-stat ic/threading-multi/pthread/thread.o gcc.compile.c++ /boost_1_39_0/bin.v2/libs/thread/build/gcc-3.4.4/debug/link-stat ic/threading-multi/pthread/exceptions.o gcc.compile.c++ /boost_1_39_0/bin.v2/libs/thread/build/gcc-3.4.4/debug/link-stat ic/threading-multi/pthread/once.o gcc.archive /boost_1_39_0/bin.v2/libs/thread/build/gcc-3.4.4/debug/link-static/t hreading-multi/libboost_thread-gcc34-mt-d-1_39.a gcc.link bin/gcc-3.4.4/debug/threading-multi/perf_counter.exe testing.capture-output bin/gcc-3.4.4/debug/threading-multi/perf_counter.run testing.time bin/gcc-3.4.4/debug/threading-multi/perf_counter.time user: [perf_counter.run] 0.122000 system: [perf_counter.run] 0.108000 ...updated 15 targets... I would like to build all the executables targets once, and then be able to run performance tests several times. Is this possible? BTW, I need to pass some args when running the test program. I do this now as alias dir_invalid : [ run stm : -bench rbtree -dir -threads 4 -inserts 100 : : : rbtree_dir_t4_i100 ] ... ; How can I integrate run-output and time in a test suite?
