摘要： A method for managing allocation of network resources within the distributed computer system is provided. Specifically, the network traversal time and the end node response time for requests and/or packets being routed in a switch-connected system area network are utilized to determine the total round trip time for completion of the particular network operation. The sum of the timeout values for all switches that participate in routing the request from a requester (source) to the receptor node (target) is provided to the requester's channel adapter (CA). The time-out values are provided by the switch manufacturer and are sent to a network Subnet Manager (SM) via SM packets (SMP). The timeout values added together represent the SubnetTimeout. The time-out value of the target channel adapter (CA), the ResponseTime, is also provided to the requester. The requester then utilizes one of two timeout equations to calculate the overall response time required for the request to be completed. A timer is started and the elapsed time to complete the request is monitored and compared with the overall response time calculated. When the timer expires before a response is received at the requester, the operation is assumed to have failed and the network resources being utilized by the request may be reallocated to another network operation.
摘要翻译：提供了一种管理分布式计算机系统内网络资源分配的方法。具体地，利用在交换机连接的系统区域网络中路由的请求和/或分组的网络遍历时间和终止节点响应时间来确定完成特定网络操作的总往返时间。参与将请求从请求者（源）路由到接收节点（目标）的所有交换机的超时值的总和提供给请求者的信道适配器（CA）。超时值由交换机制造商提供，并通过SM数据包（SMP）发送到网络子网管理器（SM）。添加的超时值表示SubnetTimeout。目标通道适配器（CA）的超时值ResponseTime也提供给请求者。然后，请求者使用两个超时方程之一来计算请求完成所需的总体响应时间。启动定时器，并监视完成请求的经过时间，并与计算的总响应时间进行比较。当定时器在请求者接收到响应之前到期时，假设该操作已经失败，并且该请求所利用的网络资源可能被重新分配到另一个网络操作。

摘要： A method in a network computing system for managing a plurality of subnet managers in the network computing system. An identification is received of a set of subnet managers within the plurality of subnet managers. The set of subnet managers is allowed to participate in a master election to select a master subnet manager. Subnet managers other than the set of subnet managers are placed in a dormant state. The master subnet manager is elected from the set of subnet managers through the master election, wherein other subnet managers within the number of subnet managers poll the master subnet manager to allow the other subnet managers to elect a new master subnet manager if the master subnet manager fails.

摘要： A method in a node within network computing system for selecting a master network manager, wherein the first node is associated with a first priority. Requests are sent to the network computing system to discover other nodes within the network computing system. A second priority from the request is identified in response to receiving a response to one of the requests from another node within the network computing system. The first node shifts to a standby mode if it discovers a master subnet manager or the second priority is higher than the first priority. The first node shifts to a master mode if a response containing a priority higher than the first priority is absent in responses received by the first node and the first node has completed checking all other nodes in the network computing system. In the case where the priority received is equal, the comparison is further made on the globally unique identifier which is received from the same node, in which case the node with the lowest globally unique identifier wins the arbitration.

摘要： Systems and arrangements to adjust resource accessibility based upon usage modes are contemplated. Embodiments may include a supervisor instance such as an operating system that is adapted to select one or more supervisor keys from a set of supervisor keys available to the host node or platform upon which the supervisor instance is operating. The supervisor instance may select the supervisor key(s) based upon an association of the supervisor instance with a usage mode represented by a supervisor key name. In many embodiments, supervisor key names may be associated with resources via with one or more of the supervisor keys based upon the resources needed when operating in the usage modes by a system administrator. Once the supervisor instance is initialized, the supervisor instance may issue client keys that allow access to subsets of the resources available to the supervisor instance based upon usage modes of the clients.

摘要： A method, apparatus, and computer implemented instructions for transferring data. A request is sent by a requester to a responder. The request includes an amount of available processing space at the requestor. When the request is received from the responder, data is identified using the request. The data is placed into a plurality of subsequences of data packets for transfer to the requester, wherein each packet within the set of subsequences hold data in amount less than or equal to the amount of available space. These subsequences are then sent to the requestor one subsequence at a time. A new subsequence is sent each time the available processing space at the requester becomes free to process data from another subsequence. The requestor receives a subsequence from the plurality of subsequences in response to the request each time the amount of available processing space is free, wherein data within each of the set of subsequences fits within the amount of available processing space.

摘要： A first hardware thread executes a software program instruction, which instructs the first hardware thread to initiate a second hardware thread. As such, the first hardware thread identifies one or more register values accessible by the first hardware thread. Next, the first hardware thread copies the identified register values to one or more registers accessible by the second hardware thread. In turn, the second hardware thread accesses the copied register values included in the accessible registers and executes software code accordingly.

摘要： A method, apparatus, and computer program product are disclosed for collecting data about the transmission of network packets that are associated with specified applications. The packets are transmitted through a communications network fabric that is used to couple data processing systems together. A particular existing single bit in a frame header definition is selected. The bit is defined as part of the standard frame header by a communication protocol as an available bit in the frame header. The standard protocol is unchanged by the selection of this bit. An application is specified to be monitored. The selected bit is then set in each network packet that is generated by the specified application. The fabric collects performance data for each packet that has the bit set. Thus, the fabric collects performance data about a transmission of each packet that is generated by the application when that application is setting the bit.
