Benefits. Responsiveness. A program can continue running even if part of it is blocked or waiting for long I/O. Important for user interfaces. Resource Sharing. Easier to share resources between threads (shared memory) compared to between processes. programming. Adapted from David Beazley’s paper:. “An . Introduction to . Python Concurrency”. Presented at USENIX Technical Conference. San Diego, June, 2009. David . Beazley: . http://www.dabeaz.com. We think of a process (a running program) as a single entity. Our modern operating systems can run multiple concurrent processes, switching off quickly between them. Multitasking. But any single process may entail multiple components which could potentially also run concurrently. Threads, SMP, and . Microkernels. Patricia Roy.

This lecture deals with how work groups are scheduled for execution on the compute units of devices. Also explain the effects of divergence of work items within a group and its negative effect on performance. Thomas Plagemann. Slides from Otto J. Anshus, Tore Larsen. (University of Tromsø). , .
