Barrier object management using apis and spinlocks
The patent US12045668B2 outlines a computer-implemented method for managing barrier objects within a multi-core processing environment. The method involves a series of operations facilitated by Application Programming Interfaces (APIs) that allow for the controlled entry and exit of barrier objects, which are defined as arrays of spinlocks. The process begins with permitting entry into a barrier object only when it is not set, followed by acquiring a spinlock associated with a specific core. The method includes waiting for the barrier object to be reset and subsequently setting it using a different set of APIs. A key feature is the addition of a waiting queue for each core, which helps to prevent unnecessary spinning when the barrier is fully set. Upon exiting the barrier, the spinlock is released, ensuring efficient resource management.
Additionally, the patent describes a computer program product that resides on a non-transitory computer-readable medium, containing instructions that, when executed, perform the aforementioned operations. The size of the array of spinlocks is directly related to the number of cores, and the method allows for the sequential acquisition of spinlocks in a loop when setting the barrier object. Furthermore, the patent encompasses a computing system equipped with processors and memory that can execute these operations, reinforcing the method's applicability in practical computing environments. The claims emphasize the structured approach to managing concurrency and synchronization in multi-core systems, highlighting the importance of efficient barrier management in enhancing overall system performance.
