Comment (by eschnett):

 Here is what I found to be most efficient:
 - all the loops that touch only a single grid function should have a
 {{{simd}}}
 - the OpenMP parallelization should be over the grid functions instead.
 I might have made a mistake in my earlier push. (In my defence, the
 performance improvement I saw was real.) A new patch should probably be
 properly reviewed, to avoid the problems I caused last time.

 I don't know which OpenMP version is supported in general. These days I
 tend to use recent versions of GCC instead of relying on older versions of
 Intel. We might want to autoconf {{{simd}}}.
