摘要： A method, system, and storage medium for the InfiniBand™ Poll verb to support a multi-threaded environment without the use of kernel services to provide serialization for mainline Poll logic. Poll is the verb, which allows a consumer to determine which of its work requests have completed, and provides ending status. In addition to multiple concurrent threads using Poll against a single Completion Queue, Poll is serialized with Destroy Queue Pair and Destroy Completion Queue. Completion Queues are used to maintain completion status for work requests. Queue Pairs are used to submit work requests and are related to a Completion Queue at the time they are created.

摘要： A method and apparatus for selectively using input/output (I/O) buffers as a retransmit vehicle in a client/server system. The decision whether to use an I/O buffer as a retransmit vehicle is based on a number of factors, including the packet size, the expected round-trip time (RTT) for an acknowledgment of the transmission, the number of I/O buffers currently allocated, and the number of I/O buffers remaining. If the decision is made not to use the I/O buffer as a retransmit vehicle, then the data is copied into a send buffer that is maintained by the system for the particular requester. Initially three threshold values, the round-trip time (RTT) threshold, the critical threshold, and the tight buffer threshold, are set. Connections having a longer round-trip time than a set round-trip time threshold or connections made when the number of I/O buffers remaining is below the critical threshold are not allowed to keep the I/O buffer as a retransmission vehicle. If the number of I/O buffers remaining falls below the critical threshold, a critical stabilization interval is started. During a critical stabilization interval, the I/O buffers may not be used as a retransmit vehicle if the number of I/O buffers already allocated exceeds the tight buffer threshold, even if the number of I/O buffers remaining is above the critical threshold. For each I/O buffer, a use count is maintained of the number of packets in the buffer awaiting acknowledgment. The use count is decremented each time an acknowledgment is received for one of the packets in the I/O buffer. When the use count has been decremented to zero, the I/O buffer is freed.

摘要： A method and apparatus for handling outgoing communication requests in an information handling system in which outgoing communication packets are accumulated into a block that is written to an input/output (I/O) device. For each I/O device there is generated a blocking factor representing a predetermined number of packets that are accumulated before the block is written to the I/O device, as well as a push interval representing a maximum period of time for which any packet in the block can be stalled. Upon the arrival of a new outgoing packet, the packet is added to the block, and the block is written to the I/O device if either the block now contains the predetermined packets or any packet in the packet has been waiting for more than the push interval. A timer running asynchronously with the arrival of outgoing requests periodically pops to write the block to the I/O device if it has been waiting overlong, even if no new requests have arrived. Both the blocking factor and the push interval are periodically adjusted in accordance with the actual throughput so that the blocking factor corresponds to the exact level of consistent parallelism for a given workload.

摘要： Distributed computing environment (DCE) remote procedure calls (RPCs) are integrated with an advisory work load manager (WLM) to provide a way to intelligently dispatch RPC requests among the available application server processes. The routing decisions are made dynamically (for each RPC) based on interactions between the location broker and an advisory work load manager. Furthermore, when the system contains multiple coupled processors (tightly coupled within a single frame, or loosely coupled within a computing complex, a local area network (LAN) configuration, a distributed computing environment (DCE) cell, etc.), the invention extends to balance the processing of RPC requests and the associated client sessions across the coupled systems. Once a session is assigned to a given process, the invention also supports performance monitoring and reporting, dynamic system resource allocation for the RPC requests, and potentially any other benefits that may be available through the specific work load manager (WLM).

摘要： A method of facilitating computing-environment control of a resource to be accessed by existing program code is provided which includes transparently replacing an uncontrolled resource referenced by existing program code with a resource controlled by a computing environment. The method also includes transparently interposing at least one resource management service of the computing environment between the existing program code and the resource controlled by the computing environment, wherein the at least one resource management service provides computing-environment control of the resource to be accessed by the existing program code. The replacing of the uncontrolled resource prevents the existing program code from directly accessing the resource.

摘要： A sectioned ordered queue in an information handling system comprises a plurality of queue sections arranged in order from a first queue section to a last queue section. Each queue section contains one or more queue entries that correspond to available ranges of real storage locations and are arranged in order from a first queue entry to a last queue entry. Each queue section and each queue entry in the queue sections having a weight factor defined for it. Each queue entry has an effective weight factor formed by combining the weight factor defined for the queue section with the weight factor defined for the queue entry. A new entry is added to the last queue section to indicate a newly available corresponding storage location, and one or more queue entries are deleted from the first section of the queue to indicate that the corresponding storage locations are no longer available. Various processes associated with a real storage manager are responsible for keeping the queue sections in balance, updating the queue sections, and removing entries from the queue to “steal” real storage frames.

摘要： Apparatus and accompanying methods for use preferably in a multi-system shared data (sysplex) environment (100), wherein each system (110) provides one or more servers (115), for dynamically and adaptively assigning and balancing new work and for new session requests, among the servers in the sysplex, in view of attendant user-defined business importance of these requests and available sysplex resource capacity so as to meet overall business goals. Specifically, systems and servers are categorized into two classes: eligible, i.e., goal-oriented servers running under a policy and for which capacity information is currently available, and candidate, i.e., servers which lack capacity information. Work requests for a client application are assigned first to various eligible systems and eligible servers thereon based on their current capacity to accept new work and in a manner that meets business goals inherent in a sysplex policy; followed, if additional servers are requested by that application, to candidate systems and candidate servers thereon. As to session placement, first those system(s) are selected that have lowest utilization, at a target importance level, but with sufficient available capacity at that level. Competing servers on the selected system(s) are then evaluated based on their corresponding session count data to yield a single resulting server. Thereafter, identification of multiple servers and their corresponding weights are returned to, e.g., a client application, for eventual routing of work requests to those servers, or the identification of a single server is returned to that application for establishing a new session therewith.

摘要： A system for porting code from a native platform to a non-native platform is provided which utilizes a non-native, platform-specific layer of code and a platform-neutral layer of code. The platform-neutral layer substantially emulates the native platform of ported code and provides a platform-neutral interface to the ported code. Together, the platform-specific layer and the platform-neutral layer provide an execution environment in which the ported code operates as a kernel extension of the non-native platform. The platform-neutral layer of the execution environment is portable to other non-native platforms so that code can be ported to another non-native platform by replacing the platform-specific layer with a customized platform-specific layer, which is adapted to the other non-native platform.

摘要： A single non-privileged instruction copies a page of data from a source virtual address in an electronic medium to a destination virtual address in the same or in a different electronic storage medium, and without the intervention of any supervisory program when each medium and the virtual addresses are previously determined. The instruction is not required to specify which medium it will use, does not require its user to know what backing medium it will access, does not require main storage (MS) to be its backing medium, and allows different types of physical addressing to be used by different media. The instruction can lock any page for use in a multi-processor (MP). No physical direction of data movement is provided within the non-privileged machine instruction, which only designates virtual direction of movement. The separation of virtual direction from physical direction is done by avoiding instruction control over selection of electronic media. The non-privileged instruction can nevertheless express a preference for obtaining a copy of the destination page in an electronic medium in which the content of the page can be processed by further instructions. Also, the instruction can cause invocation of a privileged control program to avoid the need for a following condition code test instruction. A privileged instruction is also provided to wait for the completion of the unprivileged instruction and to invalidate a non-MS medium page whether it is unlocked or locked, either correctly or incorrectly.
