摘要： A wake-and-go mechanism is provided for a data processing system. When a thread is waiting for an event, rather than performing a series of get-and-compare sequences, the thread updates a wake-and-go array with a target address associated with the event. The thread then goes to sleep until the event occurs. The wake-and-go array may be a content addressable memory (CAM). When a transaction appears on the symmetric multiprocessing (SMP) fabric that modifies the value at a target address in the CAM, the CAM returns a list of storage addresses at which the target address is stored. The operating system or a background sleeper thread associates these storage addresses with the threads waiting for an even at the target addresses, and may wake the one or more threads waiting for the event.

摘要： A wake-and-go mechanism is provided with a central repository wake-and-go array for a multiple processor data processing system. The wake-and-go mechanism recognizes a programming idiom that indicates that a thread running on a processor within the multiple processor data processing system is waiting for an event. The wake-and-go mechanism updates a central repository wake-and-go array with a target address associated with the event. Each entry in the central repository wake-and-go array may include a thread identification (ID), a central processing unit (CPU) ID, the target address, the expected data, a comparison type, a lock bit, a priority, and a thread state pointer, which is the address at which the thread state information is stored.

摘要： A wake-and-go mechanism is provided for a data processing system. The wake-and-go mechanism is configured to issue a look-ahead load command on a system bus to read a data value from a target address and perform a comparison operation to determine whether the data value at the target address indicates that an event for which a thread is waiting has occurred. In response to the comparison resulting in a determination that the event has not occurred, the wake-and-go engine populates a wake-and-go storage array with the target address and snooping the target address on the system bus without data exclusivity. In response to the comparison resulting in a determination that the event has occurred, the wake-and-go engine issues a load command on the system bus to read the data value from the target address with data exclusivity.

摘要： A remote update programming idiom accelerator is configured to detect a complex remote update programming idiom in an instruction sequence of a thread. The complex remote update programming idiom includes a read operation for reading data from a storage location at a remote node, a sequence of instructions for performing an update operation on the data to form result data, and a write operation for writing the result data to the storage location at the remote node. The remote update programming idiom accelerator is configured to determine whether the sequence of instructions is longer than an instruction size threshold and responsive to a determination that the sequence of instructions is not longer than the instruction size threshold, transmit the complex remote update programming idiom to the remote node to perform the update operation on the data at the remote node.

摘要： A hardware wake-and-go mechanism is provided for a data processing system. The wake-and-go mechanism looks ahead in a thread for programming idioms that indicates that the thread is waiting for an event. The wake-and-go mechanism performs a look-ahead polling operation for each of the programming idioms. If each of the look-ahead polling operations fails, then the wake-and-go mechanism updates a wake-and-go array with a target address associated with the event for each recognized programming idiom.

摘要： A hardware private array is a thread state storage that is embedded within the processor or within logic associated with a bus or wake-and-go logic. The hardware private array and/or wake-and-go array may have a limited storage area. Therefore, each thread may have an associated priority. If there is insufficient space in the hardware private array, then the wake-and-go mechanism may compare the priority of the thread to the priorities of the threads already stored in the hardware private array and wake-and-go array. If the thread has a higher priority than at least one thread already stored in the hardware private array and wake-and-go array, then the wake-and-go mechanism may remove a lowest priority thread, meaning the thread is removed from hardware private array and wake-and-go array and converted to a flee model.

摘要： A hardware wake-and-go mechanism is provided for a data processing system. The wake-and-go mechanism looks ahead in the instruction stream of a thread for programming idioms that indicates that the thread is waiting for an event. The wake-and-go mechanism updates a wake-and-go array with a target address associated with the event for each recognized programming idiom. When the thread reaches a programming idiom, the thread goes to sleep until the event occurs. The wake-and-go array may be a content addressable memory (CAM). When a transaction appears on the symmetric multiprocessing (SMP) fabric that modifies the value at a target address in the CAM, the CAM returns a list of storage addresses at which the target address is stored. The wake-and-go mechanism associates these storage addresses with the threads waiting for an even at the target addresses, and may wake the one or more threads waiting for the event.

摘要： A wake-and-go mechanism is provided for a data processing system. The wake-and-go mechanism detects a thread running on a first processing unit within a plurality of processing units that is waiting for an event that modifies a data value associated with a target address. The wake-and-go mechanism creates a wake-and-go instance for the thread by populating a wake-and-go storage array with the target address. The operating system places the thread in a sleep state. Responsive to detecting the event that modifies the data value associated with the target address, the wake-and-go mechanism assigns the wake-and-go instance to a second processing unit within the plurality of processing units. The operating system on the second processing unit places the thread in a non-sleep state.
