摘要： A method, system, and computer usable program product for fast remote communication and computation between processors are provided in the preferred embodiments. A direct core to core communication unit (DCC) is configured to operate with a first processor, the first processor being a remote processor. A memory associated with the DCC receives a set of bytes, the set of bytes being sent from a second processor. An operation specified in the set of bytes is executed at the remote processor such that the operation is invoked without causing a software thread to execute.
摘要翻译：在优选实施例中提供了用于处理器之间的快速远程通信和计算的方法，系统和计算机可用程序产品。核心通信单元（DCC）的直接核心被配置为与第一处理器一起操作，第一处理器是远程处理器。与DCC相关联的存储器接收一组字节，该字节集合是从第二处理器发送的。在远程处理器中执行在该组字节中指定的操作，使得在不使软件线程执行的情况下调用该操作。

摘要： Mechanisms are provided for debugging application code using a content addressable memory. The mechanisms receive an instruction in a hardware unit of a processor of the data processing system, the instruction having a target memory address that the instruction is attempting to access. A content addressable memory (CAM) associated with the hardware unit is searched for an entry in the CAM corresponding to the target memory address. In response to an entry in the CAM corresponding to the target memory address being found, a determination is made as to whether information in the entry identifies the instruction as an instruction of interest. In response to the entry identifying the instruction as an instruction of interest, an exception is generated and sent to one of an exception handler or a debugger application. In this way, debugging of multithreaded applications may be performed in an efficient manner.
摘要翻译：提供了使用内容可寻址存储器调试应用程序代码的机制。机构在数据处理系统的处理器的硬件单元中接收指令，该指令具有指令尝试访问的目标存储器地址。搜索与硬件单元相关联的内容可寻址存储器（CAM），以对应于目标存储器地址的CAM中的条目。响应于与所找到的目标存储器地址相对应的CAM中的条目，确定条目中的信息是否将该指令识别为感兴趣的指令。响应于将该指令识别为感兴趣的指令的条目，生成异常并将其发送到异常处理程序或调试器应用程序之一。以这种方式，可以以有效的方式执行多线程应用程序的调试。
