Detailed Description

Class to contain SST Simulation Configuration variables.

NOTE: This class needs to be serialized for the sst.x executable, but not for the sst (wrapper compiled from the boot*.{h,cc} files) executable. To avoid having to compile all the serialization code into the bootstrap executable, the Config class is the first level of class hierarchy to inherit from serializable.

Member Function Documentation

◆ enable_sig_handling()

bool SST::Config::enable_sig_handling ( ) const

inline

Controls whether the environment variables that SST sees are printed out.

Included in ConfigShared bool print_env() const { return print_env_; } Included in ConfigShared bool no_env_config() const { return no_env_config_; } Controls whether signal handlers are enable or not. NOTE: the sense of this variable is opposite of the command1 line option (–disable-signal-handlers)

◆ enabledProfiling()

const std::string& SST::Config::enabledProfiling ( ) const

inline

Library path to use for finding element libraries (will replace the libpath in the sstsimulator.conf file)

Included in ConfigShared const std::string& libpath() const { return libpath_; } Paths to add to library search (adds to libpath found in sstsimulator.conf file)

Included in ConfigShared const std::string& addLibPath() const { return addLibPath_; } Profiling points to turn on

Referenced by SST::Simulation_impl::createSimulation().

◆ num_threads()

uint32_t SST::Config::num_threads ( ) const

inline

Level of verbosity to use in the core prints using Output.verbose or Output.debug.

Included in ConfigShared uint32_t verbose() const { return verbose_; } Number of threads requested

◆ output_dot()

const std::string& SST::Config::output_dot ( ) const

inline

File to output dot formatted config graph to (empty string means no output).

Note, this is not a format that can be used as input for simulation

◆ parallel_load()

bool SST::Config::parallel_load ( ) const

inline

Controls whether graph constuction will be done in parallel.

If it is, then the SDL file name is modified to add the rank number to the file name right before the file extension, if parallel_load_mode_multi is true.

◆ runMode()

SimulationRunMode SST::Config::runMode ( ) const

inline

Run mode to use (Init, Both, Run-only).

Note that Run-only is not currently supported because there is not component level checkpointing.

◆ timeBase()

const std::string& SST::Config::timeBase ( ) const

inline

Core timebase to use as the atomic time unit for the simulation.

It is usually best to just leave this at the default (1ps)
