摘要： A barrier synchronization register, accessible to the nodes in a distributed data processing system, has portions thereof allotted to threads which are present in multiple groups. The barrier synchronization register portion allotted to a given thread has stored therein, over time, group identifier numbers. In this way the state space of a barrier synchronization register is shared over more than one group of process threads.

摘要： In a multinode data processing system in which nodes exchange information over a network or through a switch, the mechanism which enables out-of-order data transfer via Remote Direct Memory Access (RDMA) also provides a corresponding ability to carry out broadcast operations, multicast operations, third party operations and conditional RDMA operations. In a broadcast operation a source node transfers data packets in RDMA fashion to a plurality of destination nodes. Multicast operation works similarly except that distribution is selective. In third party operations a single central node in a cluster or network manages the transfer of data in RDMA fashion between other nodes or creates a mechanism for allowing a directed distribution of data between nodes. In conditional operation mode the transfer of data is conditioned upon one or more events occurring in either the source node or in the destination node.
摘要翻译：在节点通过网络交换信息或通过交换机交换信息的多节点数据处理系统中，通过远程直接存储器访问（RDMA）实现无序数据传输的机制也提供了相应的能力来执行广播操作，组播操作，第三方操作和有条件的RDMA操作。在广播操作中，源节点以RDMA方式将数据分组传送到多个目的节点。组播操作的工作方式类似，除了分发是有选择性的。在第三方操作中，集群或网络中的单个中央节点以RDMA方式在其他节点之间管理数据传输，或者创建一种允许在节点之间定向分发数据的机制。在条件操作模式中，数据的传输是在源节点或目标节点中发生的一个或多个事件的条件。

摘要： An addressing model is provided where devices, including I/O devices, are addressed with internet protocol (IP) addresses, which are considered part of the virtual address space. A task, such as an application, may be assigned an effective address range, which corresponds to addresses in the virtual address space. The virtual address space is expanded to include Internet protocol addresses. Thus, the page frame tables are also modified to include entries for IP addresses and additional properties for devices and I/O. Thus, a processing element, such as an I/O adapter or even a printer, for example, may also be addressed using IP addresses without the need for library calls, device drivers, pinning memory, and so forth. This addressing model also provides full virtualization of resources across an IP interconnect, allowing a process to access an I/O device across a network.

摘要： Disclosed are a method, a system and a computer program product for automatically allocating and de-allocating resources for jobs executed or processed by one or more supercomputer systems. In one or more embodiments, a supercomputing system can process multiple jobs with respective supercomputing resources. A global resource manager can automatically allocate additional resources to a first job and de-allocate resources from a second job. In one or more embodiments, the global resource manager can provide the de-allocated resources to the first job as additional supercomputing resources. In one or more embodiments, the first job can use the additional supercomputing resources to perform data analysis at a higher resolution, and the additional resources can compensate for an amount of time the higher resolution analysis would take using originally allocated supercomputing resources.

摘要： In a multinode data processing system in which the nodes communicate with one another via communication adapters over a network or switch, the adapters are provided with a dual register mechanism for tracking microcode task status. Upon the issuance of a disruptive command that requires attention from one of the nodes, the task status maintained in one register is copied to the snapshot register. As tasks within the adapter are completed, both registers are updated, thus providing a mechanism for the nodes to determine that all tasks active at the time of the disruptive command have completed. This means that the nodes now have a mechanism for determining, as soon as possible, that all tasks that are active when a disruptive command occurs have completed, thus allowing the data processing node to perform such operations as releasing system memory that is associated with the disruptive command, thus eliminating temporal overhead that can affect performance.

摘要： In remote direct memory access transfers in a multinode data processing system in which the nodes communicate with one another through communication adapters coupled to a switch or network, failures in the nodes or in the communication adapters can produce the phenomenon known as trickle traffic, which is data that has been received from the switch or from the network that is stale but which may have all the signatures of a valid packet data. The present invention addresses the trickle traffic problem in two situations: node failure and adapter failure. In the node failure situation randomly generated keys are used to reestablish connections to the adapter while providing a mechanism for the recognition of stale packets. In the adapter failure situation, a round robin context allocation approach is used with adapter state contexts being provided with state information which helps to identify stale packets. In another approach to handling the adapter failure situation counts are assigned which provide an adapter failure number to the node which will not match a corresponding number in a context field in the adapter, thus enabling the identification of stale packets.
