    Abstract: An optimization system to apply directives to a computer program without having to perform repeated front-end compilations of source code of the computer program is provided. In some embodiments, the optimization system performs a first compilation of the source code of the program to generate first front-end code and first back-end code of the computer program. The compilation includes a first front-end compilation and a first back-end compilation. The optimization system identifies a compiler directive to apply to a location within the first front-end code. The optimization system then performs a second back-end compilation of the first front-end code factoring in the compiler directive to generate second back-end code affected by the compiler directive.

    Abstract: A method and system for detecting congestion in a network of nodes, abating the network congestion, and identifying the cause of the network congestion is provided. A congestion detection system may comprise a detection system, an abatement system, and a causation system. The detection system monitors the performance of network components such as the network interface controllers and tiles of routers to determine whether the network is congested such that a delay in delivering packets becomes unacceptable. Upon detecting that the network is congested, an abatement system abates the congestion by limiting the rate at which packets are injected into the network from the nodes. Upon detecting that the network is congested, a causation system may identify the job that is executing on a node that is the cause of the network congestion.

    Abstract: An improved method for the prevention of deadlock in a massively parallel processor (MPP) system wherein, prior to a process sending messages to another process running on a remote processor, the process allocates space in a deadlock-avoidance FIFO. The allocated space provides a “landing zone” for requests that the software process (the application software) will subsequently issue using a remote-memory-access function. In some embodiments, the deadlock-avoidance (DLA) function provides two different deadlock-avoidance schemes: controlled discard and persistent reservation. In some embodiments, the software process determines which scheme will be used at the time the space is allocated.

    Abstract: A system for updating an index into a tuple table of tuples is provided. An indexing system updates an index into a tuple table using fine-grain locking of the index. The index includes a values table with an entry for each index value of an index field that references a value-tuple table that includes, for each tuple with the index value, a row that identifies a tuple of the tuple table with that indexed value. After a new tuple is added to the tuple table with a value, the index is updated by locking the entry in the values table, updating the value-tuple table for the value, and then unlocking the entry. When the index is accessed for locating tuples with a value, the accessor locks the entry in the values table for the value, uses the value-tuple table to locate the tuples, and unlocks the entry.

    Abstract: A system for providing cross-exception event handling is provided. The system allows a source thread to throw an event (e.g., exception) as part of structured event handling of a programming language that specifies a target thread. When the event is thrown, the source thread starts a handler thread to handle the event in a current context of the target thread. The handler thread is passed an indication of the event and the target thread and sets its context to be consistent with that of handling events in the target thread. The handler thread then handles the event. The source thread may continue its execution in parallel or may terminate its execution as specified in a statement that threw the event. Execution of the target thread may be aborted and its execution continued at an exit statement of an enclosing structured event handling construct—as specified when the event was thrown.

    Abstract translation: 提供了一种用于提供跨异常事件处理的系统。 该系统允许源线程抛出事件（例如，异常）作为指定目标线程的编程语言的结构化事件处理的一部分。 当事件被抛出时，源线程启动处理程序线程来处理目标线程的当前上下文中的事件。 处理程序线程传递事件和目标线程的指示，并将其上下文设置为与目标线程中处理事件的上下文一致。 处理程序线程然后处理事件。 源线程可以并行地继续其执行，或者可以终止其在抛出事件的语句中指定的执行。 目标线程的执行可能会被中止，并且在执行结束事件处理结构的exit语句时继续执行，如抛出该事件所指定的那样。
