1. A method of handling conflicts between threads, including an initiating thread and at least one other thread, for at least one shared resource in a multi-threaded processing system having a processor and memory, comprising: (1) with the initiating thread, setting a location in memory for each other thread on the processor; (2) with the initiating thread, signaling an inter-processor interrupt (IPI) to all other threads on the processor; (3) for each other thread, initiating an interrupt handler where each other thread: (a) acknowledges receipt of the interrupt; and (b) proceeds to spin on the respective location in memory that was set in step ( 1 ), thereby guaranteeing that the respective other thread will not be using any shared resource of the processor; (4) the initiating thread: (a) waits for other threads on processor to acknowledge the inter-processor interrupt (IPI); and (b) when all the other threads have acknowledged the inter-processor interrupt (IPI), the initiating thread proceeds to step ( 5 ); (5) the initiating thread: (a) saves the state of the shared resource in memory; (b) sets the shared resource to the state wanted; (c ) uses the shared resource; and (d) restores the original state of the resource; (6) the initiating thread releases the other threads from their spin by resetting the location in memory that was set in step ( 1 ); and (7) all the threads proceed with their computations.
