摘要： Techniques for grouping two or more threads based on lock contention information are provided. The techniques include determining lock contention information with respect to two or more threads, using the lock contention information with respect to the two or more threads to determine lock affinity between the two or more threads, using the lock affinity between the two or more threads to group the two or more threads into one or more thread clusters, and using the one or more thread clusters to perform scheduling of one or more threads.

摘要： A method and system are provided for load balancing and partial task-processor binding. The method may provide for migrating at least one first task partially bound to and executing on at least one first processor. In accordance with the method, if at least one first condition is true, then the at least one first task may be migrated to at least one second processor such that the at least one second processor executes the at least one first task. Moreover, in accordance with the method, if at least one second condition is true, the at least one first task may be migrated back to the at least one first processor such that the at least one first processor executes the at least one first task.

摘要： A method and system for decoupling a central processing unit (CPU) of a plurality of hot CPUs from its assigned tasks. The hot CPUs are managed by an operating system of a computer system. A special flag is set, denoting that the CPU is to be decoupled from its assigned tasks. A special task coupled to the CPU is given a suitable scheduling policy and priority, wherein the special task gets enough continuous execution time to finish its job before another task executes on the CPU. The special task examines the special flag and decouples the first CPU from its assigned tasks after determining that the special flag has been set, wherein the special task does not relinquish control of the CPU. The decoupling of tasks from the CPU leaves at least one remaining CPU and occurs while the at least one remaining CPU is hot.

摘要： Debugging multiple tasks, using a single instance of a debugger application intended to be only capable of debugging a single task, is performed by intercepting system calls made by the debugger application to the operating system. The intercepted system calls are directed to an appropriate task, which is one amongst the multiple tasks to be debugged.
