Abstract: A concurrency-restricting lock may divide a set of threads waiting to acquire the lock into an active circulating set (ACS) that contends for the lock, and a passive set (PS) that awaits an opportunity to contend for the lock. The lock, which may include multiple constituent lock types, lists, or queues, may be unfair over the short term, but improve throughput of the underlying multithreaded application. Culling and long-term fairness policies may be applied to the lock to move excess threads from the ACS to the PS or promote threads from the PS to the ACS. These policies may constraint the size or distribution of threads in the ACS (which may be NUMA-aware). A waiting policy may avoid aggressive promotion from the PS to the ACS, and a short-term fairness policy may move a thread from the tail of a list or queue to its head.

Abstract: Techniques are described herein for profiling mutual exclusion locks. In one or more embodiments, a performance profiler identifies a first thread executing an activity within a parallel processing environment. The performance profiler identifies a set of one or more mutual-exclusion locks held by the first thread while the activity is being executed and determines the total number of threads waiting for at least one of the set of mutual-exclusion locks held by the first thread. The performance profiler then determines a total cost associated with execution of the activity based at least on the total number of threads waiting for at least one of the set of mutual-exclusion locks held by the first thread during execution of the activity. In one or more embodiments, the total cost is obtained by multiplying a raw cost with the number of threads waiting.

Abstract: Dominant sequences that are representative of logged events can be artificially created. Initially, a graph comprising multiple nodes and edges between pairs of nodes is generated from logged information. The weights, or values, associated with edges are incremented as the log data reveals a temporal relationship between two nodes. Subsequently, a set of candidate trajectories, with each candidate trajectory representing a sequence of events, are generated by repeatedly traversing the generated graph in a random manner by commencing at randomly selected nodes and then proceeding in a random manner to subsequent nodes in accordance with the edge values, for a random quantity of steps. The candidate trajectories are filtered to eliminate those that are impossible or improbable based on a comparison between individual candidate trajectories and the quantity of occurrences within the logs. Scoring is based both on a quantity of occurrences as well as a quantity of steps.
