摘要： In a parallel computer executing a parallel application, where the parallel computer includes a number of compute nodes, with each compute node including one or more computer processors, the parallel application including a number of processes, and one or more of the processes executing a barrier operation, creating a checkpoint of a parallel application includes: maintaining, by each computer processor, global barrier operation state information, the global barrier operation state information includes an aggregation of each process's barrier operation state information; invoking, for each process of the parallel application, a checkpoint handler; saving, by each process's checkpoint handler as part of a checkpoint for the parallel application, the process's barrier operation state information; and exiting, by each process, the checkpoint handler.

摘要： A job may be divided into multiple tasks that may execute in parallel on one or more compute nodes. The tasks executing on the same compute node may be coordinated using barrier synchronization. However, to perform barrier synchronization, the tasks use (or attach) to a barrier synchronization register which establishes a common checkpoint for each of the tasks. A leader task may use a shared memory region to publish to follower tasks the location of the barrier synchronization register—i.e., a barrier synchronization register ID. The follower tasks may then monitor the shared memory to determine the barrier synchronization register ID. The leader task may also use a count to ensure all the tasks attach to the BSR. This advantageously avoids any task-to-task communication which may reduce overhead and improve performance.

摘要翻译：作业可以被划分为可以在一个或多个计算节点上并行执行的多个任务。可以使用屏障同步来协调在相同计算节点上执行的任务。然而，为了执行屏障同步，任务使用（或附加）到屏障同步寄存器，其为每个任务建立公共检查点。领导任务可以使用共享存储器区域向跟随者任务发布屏障同步寄存器的位置，即屏障同步寄存器ID。随后的任务可以监视共享存储器以确定屏障同步寄存器ID。领导任务还可以使用计数来确保所有任务附加到BSR。这有利地避免任何任务到任务的通信，这可以减少开销并提高性能。

摘要： A message flow controller limits a process from passing a new message in a reliable message passing layer from a source node to at least one destination node while a total number of in-flight messages for the process meets a first level limit. The message flow controller limits the new message from passing from the source node to a particular destination node from among a plurality of destination nodes while a total number of in-flight messages to the particular destination node meets a second level limit. Responsive to the total number of in-flight messages to the particular destination node not meeting the second level limit, the message flow controller only sends a new packet from among at least one packet for the new message to the particular destination node while a total number of in-flight packets for the new message is less than a third level limit.

摘要： A technique for debugging code during runtime includes providing, from an outside process, a trigger to a daemon. In this case, the trigger is associated with a registered callback function. The trigger is then provided, from the daemon, to one or more designated tasks of a job. The registered callback function (that is associated with the trigger) is then executed by the one or more designated tasks. Execution results of the executed registered callback function are then returned (from the one or more designated tasks) to the daemon.

摘要： A method, system, and computer program product are provided for managing a cache. A region to be stored within the cache is received. The cache includes multiple regions and each of the regions is defined by memory ranges having a starting index and an ending index. The region that has been received is stored in the cache in accordance with a cache invariant. The cache invariant guarantees that at any given point in time the regions in the cache are stored in a given order and none of the regions are completely contained within any other of the regions.
