What happens (specify any output generated) when the following program code is executed on a cluster of 4 nodes.

What happens (specify any output generated) when the following program code is

int size, node; MPI Init(&argc, &argv); MPI Comm rank(MPI COMM WORLD, &node): MPI Comm size(MPI COMM WORLD, &size): if(node 0) a-1:5-2; MPI Recv(&a, 1, MPI INT, 1,0, MPI COMM WORLD. &status); MPI Sends&b. 1. MPI INT. 1.0. MPI COMM WORLD): else a-101; b-102; MPI Recv(&a, 1, MPI INT, 0, 0, MPI COMM WORLD. &status); MPI Send(&b, 1, MPI INT, 0, 0, MPI COMM WORLD) MPI Finalize)
