#define forAll(list, i)
Loop across all elements in list.
intWM_LABEL_SIZE_t label
A label is an int32_t or int64_t as specified by the pre-processor macro WM_LABEL_SIZE.
A 1D array of objects of type <T>, where the size of the vector is known and used for subscript bound...
static int myProcNo(const label communicator=0)
Number of this process (starting from masterNo() = 0)
static int nProcsSimpleSum
Number of processors at which the sum algorithm changes from linear.
Template function to specify if the data of a type are contiguous.
#define forAllReverse(list, i)
Reverse loop across all elements in list.
static const List< commsStruct > & linearCommunication(const label communicator=0)
Communication schedule for linear all-to-master (proc 0)
Input inter-processor communications stream.
static const List< commsStruct > & treeCommunication(const label communicator=0)
Communication schedule for tree all-to-master (proc 0)
Structure for communicating between processors.
static void scatter(const List< commsStruct > &comms, T &Value, const int tag, const label comm)
Scatter data. Distribute without modification. Reverse of gather.
static label read(const commsTypes commsType, const int fromProcNo, char *buf, const std::streamsize bufSize, const int tag=UPstream::msgType(), const label communicator=0)
