4.2Odd-Even Sort Using OpenMP SAUCE can also be used to teach parallel programming on shared memory architectures. In this paper, we present a multi-threaded example based on OpenMP. The parallelization of Odd-Even Sort, a modified variant of Bubble Sort that interleaves swaps of odd and even...
Bubble Sort Odd-Even Sort 1. Scatter the array onto processors. 2. Sort each sub-array aa. 3. Repeat for step=0,1,2,…, p-1 if (step is odd){ if(rank is odd)exchange(aa,n/size,rank, rank+1); if(rank is even) exchange(aa,n/size,rank-1, rank); } if (step is even){...
Communication cost model Processes spend some time doing useful work, and some time communicating Model communication cost as TC = ts + L tb L = message size Independent of location of processes Any process can communicate with any other process A process can simultaneously send and receive one ...
