摘要： Methods, apparatus and systems for facilitating one-way ordering of otherwise independent message classes. A one-way message ordering mechanism facilitates one-way ordering of messages of different message classes sent between interconnects employing independent pathways for the message classes. In one aspect, messages of a second message class may not pass messages of a first message class. Moreover, when messages of the first and second classes are received in sequence, the ordering mechanism ensures that messages of the first class are forwarded to, and received at, a next hop prior to forwarding messages of the second class.
摘要翻译：用于促进独立消息类别的单向排序的方法，装置和系统。单向消息排序机制有助于在使用消息类的独立路径的互连之间发送的不同消息类别的消息的单向排序。在一个方面，第二消息类的消息可能不会传递第一消息类的消息。此外，当顺序地接收到第一类和第二类的消息时，排序机制确保在转发第二类的消息之前将第一类的消息转发到下一跳并在其中接收。

摘要： Each processor in a distributed shared memory system has an associated memory and a coherence directory. The processor that controls a memory is the Home processor. Under certain conditions, another processor may obtain exclusive control of a data block by issuing a Load Lock instruction, and obtaining a writeable copy of the data block that is stored in the cache of the Owner processor. If the Owner processor does not complete operations on the writeable copy of the data prior to the time that the data block is displaced from the cache, it issues a Victim To Shared message, thereby indicating to the Home processor that it should remain a sharer of the data block. In the event that another processor seeks exclusive rights to the same data block, the Home processor issues an Invalidate message to the Owner processor. When the Owner processor is ready to resume operation on the data block, the Owner processor again obtains exclusive control of the data block by issuing a Read-with Modify Intent Store Conditional instruction to the Home processor. If the Owner processor is still a sharer, a writeable copy of the data block is sent to the Owner processor, who completes modification of the data block and returns it to the Home processor with a Store Conditional instruction.
摘要翻译：分布式共享存储器系统中的每个处理器具有相关联的存储器和一致性目录。控制内存的处理器是家庭处理器。在某些条件下，另一个处理器可以通过发出一个加载锁定指令，并获得存储在所有者处理器的高速缓存中的数据块的可写拷贝来获得数据块的排他控制。如果所有者处理器在数据块从高速缓存中移位之前未完成数据可写入副本的操作，则它发出受害者共享消息，从而向家庭处理器指示它应该保持为数据块。在另一个处理器寻求对相同数据块的独占权限的情况下，家庭处理器向所有者处理器发出无效消息。当所有者处理器准备好在数据块上恢复操作时，所有者处理器通过向家庭处理器发出读取修改意向存储条件指令，再次获得数据块的排他控制。如果所有者处理器仍然是一个共享者，则可将数据块的可写拷贝发送给所有者处理器，所有者处理器完成对数据块的修改，并使用存储条件指令将其返回到家庭处理器。

摘要： Methods and apparatus relating to improving the value of F-state by increasing a local caching agent's data forwarding are described. In one embodiment, the opportunity for forwarding from a local caching agent is improved by allowing the local caching agent to keep an F-state copy of the line while sending an S-state copy to the requestor (e.g., in response to a non-ownership read operation). Other embodiments are also disclosed.

摘要： Methods and apparatus relating to an inter-queue anti-starvation mechanism with dynamic deadlock avoidance in a retry based pipeline are described. In one embodiment, logic may arbitrate between two queues based on various rules. The queues may store data including local or remote requests, data responses, non-data responses, external interrupts, etc. Other embodiments are also disclosed.
