摘要： An approach is provided to improve network efficiency. A send segment size, such as a maximum segment size (MSS), that corresponds to data segments being sent to a receiver over a computer network. A data block is identified in a send buffer and the data block includes more than one data segments. Based on the determined send segment size, all but a remaining data segment of the data segments are sent to the receiver. The sent data segments are each the determined send segment size and the remaining data segment is smaller than the send segment size. The remaining data segment is sent to the receiver in response to identifying that the remaining data segment is a portion of the data block.

摘要： A method, system, and program for managing memory page requests in a multi-processor data processing system determines a threshold value of available memory, and dynamically adjusts an allocation time to fulfill a page request if the available memory is below a threshold value. The allocation time to fulfill the page request is based upon a percentage of available memory pages once a page stealer commences a scan for pages. An allocation wait time is inversely proportionally adjusted depending upon the percentage of available memory. The allocation wait time has a duration that increases in time as the percentage of available memory decreases and decreases in time as the percentage of available memory increases. More specifically, an average time per page to allocate a page including a scan time for the scan in computing the average time is determined. Then a tunable value is applied to the average time to determine a wait time. In a preferred embodiment, user defined values are received that would control the allocation wait time before fulfilling a page request.

摘要： A computer implemented method, apparatus, and computer usable program product for utilizing instruction trace registers. In one embodiment, a value in a target processor register in a plurality of processor registers is updated in response to executing an instruction associated with program code. In response to updating the value in the target processor register, an address for the instruction is copied from an instruction address register into an instruction trace register associated with the target processor register. The instruction trace register holds the address of the instruction that updated the value stored in the target processor register.

摘要： Identifying compatible threads in a Simultaneous Multithreading (SMT) processor environment is provided by calculating a performance metric, such as cycles per instruction (CPI), that occurs when two threads are running on the SMT processor. The CPI that is achieved when both threads were executing on the SMT processor is determined. If the CPI that was achieved is better than the compatibility threshold, then information indicating the compatibility is recorded. When a thread is about to complete, the scheduler looks at the run queue from which the completing thread belongs to dispatch another thread. The scheduler identifies a thread that is (1) compatible with the thread that is still running on the SMT processor (i.e., the thread that is not about to complete), and (2) ready to execute. The CPI data is continually updated so that threads that are compatible with one another are continually identified.

摘要： A system and method is altering the priority of a process, or thread of execution, when the process acquires a software lock. The priority is altered when the lock is acquired and restored when the process releases the lock. Thread priorities can be altered for every lock being managed by the operating system or can selectively be altered. In addition, the amount of alteration can be individually adjusted so that a process that acquires one lock receive a different priority boost than a process that acquires a different lock. Furthermore, a method of tuning a computer system by adjusting lock priority values is provided.
摘要翻译： 当进程获取软件锁时，系统和方法正在改变进程的优先级或执行的线程。 当获取锁定时，优先级会更改，并在进程释放锁定时恢复。 可以对由操作系统管理的每个锁进行线程优先级改变，或者可以有选择地改变。 此外，可以单独调整更改量，使得获取一个锁的进程与获取不同锁的进程接收到不同的优先级提升。 此外，提供了通过调整锁定优先级值来调整计算机系统的方法。
