Caveats
- The two runs were produced on different machines (ryzen-5950x-2 against ryzen-5950x-1), so the timings compare the hardware as much as the pull request. The phases a model reaches are still comparable.
- 6 of the 95 libraries were not tested in the same version, or not with the same configuration and reference files, in the two runs; see Library Changes below.
- 77 libraries of the baseline run were not tested by the pull request run: AixLib_latest, AixLib_master, Annex60, Annex60_1.0.0, Buildings, Buildings_1.6, Buildings_10, Buildings_2.0.0, Buildings_2.1.0, Buildings_3.0.0, Buildings_5.0.1, Buildings_6.0.0, Buildings_7.0.0, Buildings_8, Buildings_8.0.0, Buildings_9, Buildings_maint.7.0.x, Buildings_maint.8.0.x, Buildings_master, ConPNlib, Dynawo_1.6.1, EHPTexamples_main, EHPTlib_main, FCSys, IBPSA_master, IdealizedContact, ModelicaTestOverdetermined_3.2.2, ModelicaTest_3.1, ModelicaTest_3.1_cpp, ModelicaTest_3.2.1, ModelicaTest_3.2.1_cpp, ModelicaTest_3.2.2, ModelicaTest_3.2.2_cpp, ModelicaTest_3.2.2_fmi, ModelicaTest_3.2.2_fmi-cpp, ModelicaTest_3.2.2_fmi_cpp, ModelicaTest_3.2.3_cpp, ModelicaTest_4.1.0-beta.om, ModelicaTest_trunk_cpp, Modelica_3.1, Modelica_3.1_cpp, Modelica_3.2.1, Modelica_3.2.1_cpp, Modelica_3.2.2, Modelica_3.2.2_-O1, Modelica_3.2.2_-O2, Modelica_3.2.2__O1, Modelica_3.2.2__O2, Modelica_3.2.2_cpp, Modelica_3.2.2_fmi, Modelica_3.2.2_fmi-cpp, Modelica_3.2.2_fmi_cpp, Modelica_3.2.3_cpp, Modelica_4.1.0-beta.om, Modelica_LinearSystems2, Modelica_LinearSystems2_dev, Modelica_Noise, Modelica_StateGraph2, Modelica_Synchronous, Modelica_Synchronous_cpp, Modelica_Synchronous_fmi, Modelica_Synchronous_fmi-cpp, Modelica_Synchronous_fmi_cpp, Modelica_trunk_cpp, ObjectStab, OpenHPL, OpenIPSL_release, PowerSystems_cpp, PowerSystems_fmi, PowerSystems_fmi-cpp, PowerSystems_fmi_cpp, PowerSystems_master, SiemensPower, SiemensPower_OMCtest, SolarTherm_alberto-merge, ThermofluidStream_OM_adaptions, iPSL.
- The baseline is the newest run of master, not the commit the pull request is based on, so a difference can also come from something merged into master since the pull request was branched.
