Posix Threads (Pthreads): Transcript

Posix Threads Pthreads Concurrency Chapter 26 Abstraction Threads Here we introduce a new abstraction for a single running process that of a thread The state of a single thread is thus very similar to that of a process It has a program counter PC that tracks where the program is fetching instructions from. class simpleRunnable: public Runnable { public: simpleRunnable(int ID) : myID(ID) {} virtual void* run() { std::cout "Thread " myID " is running" std::endl; return reinterpret_castvoid*(m Single and Multithreaded Processes. 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. Readings. . Silberschatz. et al : Chapter 4. Motivation. Sometimes a program needs to do multiple tasks concurrently. Example: Word processor . Tasks include: Display graphics, respond to keystrokes from the user, and perform spelling and grammar checking. Instructor Notes. 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. Chapter 4. 2. Outline. Threads. Symmetric Multiprocessing (SMP). Microkernel. Linux Threads. 3. Process Characteristics. Unit of resource ownership. - process is allocated:. a virtual address space to hold the process image. Tausief Shaikh. (Senior Server developer).
