摘要： A system for managing threads. A kernel tread associated with a user thread is detected as being unneeded by the user tread. The kernel thread is semi-detached in which data for the thread does not change stacks in response to the kernel thread being unneeded.

摘要： Partition migrations are scheduled between virtual partitions of a virtually partitioned data processing system. The virtually partitioned data processing system is a tickless system in which a periodic timer interrupt is not guaranteed to be sent to the processor at a defined time interval. A request is received for a partition migration. Gaps between scheduled timer interrupts are identified. The partition migration is then scheduled to occur within the largest gap.

摘要： Methods, systems, and media are disclosed for autonomic system tuning of simultaneous multithreading (“SMT”). In one embodiment, the method for autonomic tuning of at least one SMT setting for an optimized processing, such as via throughput, latency, and power consumption, of a workload on a computer system includes calling, by a kernel, an SMT scheduler having at least one hook into a genetic library. Further, the method includes obtaining, by the SMT scheduler through the at least one hook, genetic data from the genetic library for the optimized processing of the workload. Further still, the method includes tuning, by the SMT scheduler and based on the obtaining, the at least one SMT setting for at least one cpu of the computer system.

摘要： Illustrative embodiments provide a computer implemented method, a data processing system and a computer program product for lock contention reduction. In one illustrative embodiment, the computer implemented method provides a lock to an active thread, increments a lock counter, receives a request to de-schedule the active thread, and determines whether the lock is held by the active thread. The computer implemented method, responsive to a determination that the lock is held by the active thread, adds a first pre-determined amount to a time slice of the active thread.

摘要： A computer implemented method, apparatus, and computer program product for preserving branch history data. The process creates a branch history table in a buffer. The process saves an address for each executed branch instruction that occurs during execution of code in the branch history table to form branch history data. In response to detecting an exception, the process saves the branch history data to an allocated memory space to form a branch history snapshot.

摘要： The illustrative embodiments described herein provide an apparatus and method for managing data in a hybrid drive system. In one embodiment, a process determines whether the detachable memory contains clean data in response to identifying that a cache portion of a detachable memory is unavailable. The clean data does not require a disk to be in a spin state to be removed from the detachable memory. The process removes the clean data from the detachable memory in response to determining that the detachable memory contains the clean data. The process stores the data on the detachable memory.

摘要： Method for balancing a binary search tree. A computer implemented method for balancing a binary search tree includes locating a node in a binary search tree, determining whether a depth of the located node is greater than a threshold, and performing balancing operations. If the depth of the located node is greater than the threshold, the balancing operations may include a modified semi-splay balancing procedure. Regardless of depth, localized balancing operations may be performed while locating a node.
