To parallelize this algorithm, we will use a mixed strategy in which the sublists are sorted by a sequential sorting algorithm and the merging of sublists is done in parallel between processes. We chose to stick with cases in which the number of processes is a power of two so that all processes are doing roughly the same amount of work.

The main assumption in cannon is that both A and B matrix must be square matrix and number of proc must be equalt to the no of elements in A matrix. In MPI, local variables only are important only to the process using them. Local variables in this problem include local_a, local_b, and local_n. Note that the values of local_a and local_b are completely dependent upon process rank. They must be specifically calculated for each process to ensure that each process receives a different subinterval.

Nov 17, 2017 · In this case, the typically fast quicksort, which computational complexity is O(N x log2(N)) in the average case, asymptotically degrades to O(N^2), which is quite similar to the complexity of any other selection- or insertion-based algorithm. In turn, it makes the using of quicksort algorithm many times less efficient when sorting datasets ...

Firstly we need to look at what the code must accomplish. Since this is most of a demonstration of MPI than trying to get the absolute fastest sort we will only be using MPI for parrallelization. And although MPI supports it we will not use shared memory since openMP does that better. It is optimized to run on a cluster or supercomputer.
