Is there any chance this could be two PRs? It's hard to understand the parallel bits when mixed into the other changes. Also note that the halo freezing stuff is done automatically in pyop3, so maybe you don't have to worry about optimising that here. |

I'm having a hard time with git. The parloop removal is the only other thing that's not adressing the bug, should be easy to ignore from the rest of the PR. |

Description
Fixes a parallel bug when reusing a matfree adjoint
Interpolator. Summation withaccess=INCskipped the halo exchange after the first call toInterpolator.assemble(). On subsequent calls the summation only happened locally within each process, but not across processes.This bug did not affect
assemble(interpolate(...))because the Interpolator there is never reused.
