jpekkila fab620eb0d Reordered reduction autotests and made it so that the exact same mesh is used for both the model and candidates instead of the unclean integrated one

main_old.cc

Found a workaround that gives good inter and intra-node performance. HPC-X MPI implementation does not know how to do p2p comm with pinned arrays (should be 80 GiB/s, measured 10 GiB/s) and internode comm is super slow without pinned arrays (should be 40 GiB/s, measured < 1 GiB/s). Made a proof of concept communicator that pins arrays that are send or received from another node.
