HcclGroup

Function

Configures a communicator name. Each name corresponds to a communicator. After the configuration, the GetHcclContext interface can be called on the kernel side to obtain the address of the context (message area) corresponding to the communicator.

Prototype

OpMC2Def &HcclGroup(const char *value)
OpMC2Def &HcclGroup(std::vector<const char *> value)

Parameters

Parameter	Input/Output	Description
value	Input	Name of the configured communicator. Use const char * for a single communicator and *std::vector<const char >** for multiple communicators.

Constraints

Before using this API, you need to register the operator as an MC2 operator through the MC2 API. After the registration, an OpMC2Def structure is returned.

The communicator name must be configured as an attribute of the REQUIRED String type. The attribute name is the communicator name.

Examples

class MC2Custom : public OpDef {
public:
    MC2Custom(const char* name) : OpDef(name)
    {
        this->Input("x").ParamType(REQUIRED).DataType({ge::DT_FLOAT}).Format({ge::FORMAT_ND});
        this->Input("y").ParamType(REQUIRED).DataType({ge::DT_FLOAT}).Format({ge::FORMAT_ND});
        this->Output("z").ParamType(REQUIRED).DataType({ge::DT_FLOAT}).Format({ge::FORMAT_ND});
        this->Attr("group").AttrType(REQUIRED).String();
        this->AICore().AddConfig("ascendxxx");
    this->MC2().HcclGroup("group"); // Set the communicator name to group.
    }
};
OP_ADD(MC2Custom);
