make the build of flow fully parallelizable so far, the actual specializations of the simulator were compiled into the `libopmsimulators` library and the build of the glue code (`flow.cpp`) thus needed to be deferred until the library was fully built. Since the compilation of the glue code requires a full property hierarchy for handling command line parameters, this arrangement significantly increases the build time for systems with a sufficient number of parallel build processes. ("sufficient" here means 8 or more threads, i.e., a quadcore system with hyperthreading is sufficient provided that it has enough main memory.) the new approach is not to include these objects in `libopmsimulators`, but to directly deal with them in the `flow` binary. this allows all of them and the glue code to be compiled in parallel. compilation time on my machine before this change: ``` > touch ../opm/autodiff/BlackoilModelEbos.hpp; time make -j32 flow 2> /dev/null Scanning dependencies of target opmsimulators [ 2%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_gasoil.cpp.o [ 2%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_oilwater.cpp.o [ 2%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_blackoil.cpp.o [ 2%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_solvent.cpp.o [ 4%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_polymer.cpp.o [ 6%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_energy.cpp.o [ 6%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_oilwater_polymer.cpp.o [ 6%] Linking CXX static library lib/libopmsimulators.a [ 97%] Built target opmsimulators Scanning dependencies of target flow [100%] Building CXX object CMakeFiles/flow.dir/examples/flow.cpp.o [100%] Linking CXX executable bin/flow [100%] Built target flow real 1m45.692s user 8m47.195s sys 0m11.533s ``` after: ``` > touch ../opm/autodiff/BlackoilModelEbos.hpp; time make -j32 flow 2> /dev/null [ 91%] Built target opmsimulators Scanning dependencies of target flow [ 93%] Building CXX object CMakeFiles/flow.dir/flow/flow.cpp.o [ 95%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_gasoil.cpp.o [ 97%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_oilwater_polymer.cpp.o [100%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_polymer.cpp.o [100%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_oilwater.cpp.o [100%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_solvent.cpp.o [100%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_blackoil.cpp.o [100%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_energy.cpp.o [100%] Linking CXX executable bin/flow [100%] Built target flow real 1m21.597s user 8m49.476s sys 0m10.973s ``` (this corresponds to a ~20% reduction of the time spend on waiting for the compiler.)
