loadAnonymousSubComponent

template <class T, class... ARGS>
T* loadAnonymousSubComponent(const std::string& type, const std::string slot_name,
    int slot_num, uint64_t share_flags, Params& params, ARGS... args);

Availability: Component, SubComponent, ComponentExtension

Load an SST SubComponent anonymously, that is, not via the simulation configuration file.

Parameters​

  • type (string) SubComponent type in lib.name format
  • slot_name (string) Name of the slot to load into
  • slot_num (int) Index in the slot to load into
  • share_flags (uint64_t) SST flags that indicate how statistics, ports, and other ELI properties should be shared between parent (Sub)Component and child SubComponent
  • params (Params) Set of parameters to pass to the SubComponent's constructor
  • args (ARGS) Additional SubComponent API-specific arguments for the SubComponent's constructor
  • returns (bool) A pointer to the newly-created SubComponent

Example​

Excerpt from sst-elements/src/sst/elements/miranda/mirandaCPU.cc
RequestGenCPU::RequestGenCPU(ComponentId_t id, Params& params) : Component(id) {
    /** Configuration here */

    // Load a StandardMem memory interface to translate our memory requests for the attached memory subsystem
    std::string interfaceName = params.find<std::string>("memoryinterface", "memHierarchy.standardInterface");
    Params interfaceParams = params.get_scoped_params("memoryinterfaceparams");
    interfaceParams.insert("port", "cache_link"); // The interface will share our port named 'cache_link'

    cache_link = loadAnonymousSubComponent<SST::Interfaces::StandardMem>(interfaceName, "memory", 0,
        ComponentInfo::SHARE_PORTS | ComponentInfo::INSERT_STATS, interfaceParams, timeConverter, 
        new Interfaces::StandardMem::Handler<RequestGenCPU>(this, &RequestGenCPU::handleEvent));
