Title: LOCALLY POLL FLAG IN MULTI PROCESSING NODE SYSTEM TO DETERMINE WHETHER A RESOURCE IS FREE TO USE FOR THREAD
Abstract:
Examples disclosed herein relate to locally polling the value of a flag to determine whether a resource is free for a thread to use in a system with multiple processing nodes that are incoherent with regards to each other. A flag in a direct attached memory to one of the processing nodes is set to indicate that the resource is not free for the thread to use. A previous tail of a lock list is determined from a list master. The previous tail is located on another one of the processing nodes.
