![]() ![]() Depending on the programming model stealing may be done in a one-sided manner (e.g. in UPC, OpenMP, Shmem, etc) or in a two sided manner (e.g. When a ''thief'' finds a ''victim'' with work, it steals a portion of the victim's work and is able to continue processing. Work sharing uses a centralized mechanism for distributing work. Work sharing can be accomplished through the use of work servers or shared work queues. In these schemes, workers send new tasks (in the case of UTS these are tree nodes) to the server or enqueue them in the queue. Scalable Dynamic Load Balancing Using UPC PDF Explicit Tasks in OpenMP 3.0 (Part of the BOTS benchmarks, Version 1.1+).Chapel (Note: This is a reference implementation and has not been tuned for performance/scalability.).Implementations in additional parallel models include: Our distribution of UTS includes implementations for: When a worker exhausts its work it can get more from the server or the shared queue.
