modelS CS 5802 Monica Borra Overview Types of parallel programming models Shared memory Model OpenMP POSIX Threads Cilk Cilk Plus Cilk Plus Plus Thread Building Blocks Types of Parallel Programming Models. Parallel programming 5 - 2 arallel Version 1. Our first parallel version simply splits the outer loop: id := process_fork (p); for (i=id; in ; i=i+p) { y [i] = 0; for (j=0; jn Pro .Net Programming in C#, Adam Freeman. Parallel C# .
