Wolfgang Bangerth [Wed, 21 Jun 2017 14:01:23 +0000 (08:01 -0600)]
Use a cheaper call.
The functions in question take an IndexSet argument that can either mean
something, or if it is empty, is ignored. In the places where an empty
IndexSet is passed, it actually has size zero, not just zero elements,
but in the existing code, we test whether 'indices.n_elements()==0'.
It turns out that 'n_elements()' is a pretty expensive function to call.
What we really wanted, of course, was 'indices.size()==0', and this
patch makes that change.
I ran all multigrid tests (the functions in question are multigrid
related), and they all succeed.

Simplify the logic of CellDataTransferBuffer::(un)pack_data().
Specifically, instead of serializing by hand with memcpy etc, use the BOOST
facilities for serialization. This works for 2 out of 3 members of this class
without problem, and the last one is easy to deal with as well.
Secondly, serialize into a gzip compressed stream to reduce the amount of data to
transfer. This reduces the size of messages significantly; for example, in the
last cycle of step-40, we get the following data -- old packet size on the left,
new (compressed) data size on the right:
6400 1694
8440 2200
8440 2412

I did also try to run things with BOOST's bzip2 compressor instead of gzip,
given that bzip2 often does a better job than gzip, but apparently that
isn't the case here as I get the following:

Remove hp::DoFHandler::MGVertexDoFs.
The hp::DoFHandler class does not support multilevel DoFs, and so having a
remnant part of the infrastructure for them makes no sense. Removing this
part from the class, however, requires a couple of specializations of
functions in the DoFAccessor class that may have previously compiled,
but would likely have led to segmentation faults if anyone tried to use them.

Inline GeometryInfo<dim>::line_to_cell_vertices.
This provides about a 5% speed boost in TransfiniteInterpolationManifold since
the compiler can rewrite the loop over the line vertices.

Use only enum values, don't look at bits.
This fixes an (undocumented) oddity in ParameterHandler::print_parameters(): We
were at times looking at individual bits instead of just the declared values
of ParameterHandler::OutputStyle. This presumably allowed for calling that
function with a combination of the OutputStyle flags, for reasons that no
longer seem particularly relevant nor obvious.
This patch removes this possibility from the current implementation of
the function, but retains it for the (deprecated) function
ParameterHandler::print_parameters_section().
