PCBDDC: explicitly setup local KSPs

so that we get a less distorted view in log_view

fixed unused var

doc and diagnostic

fixing PetscInfo %d

fixed warning

high level GAMG optimizations, pin coarse grids to CPU, add new reduced processor layout (spread accross machine or 'compact'

WIP: fixing as per suggestions, but Fortran subs are failing to make

PCBDDC: directly copy values into deluxe matrices

this speeds up a bit the setup phase

Merge branch 'master' into 'master'

Add --download-hpddm

See merge request petsc/petsc!1994

--download-hpddm for PCHPDDM and KSPHPDDM

Fixes and improvements for PCHPDDM and KSPHPDDM

Fix compilation error for nvcc in optimized code with AVX-512 (march=native on my GPU workstation)

for some reason, the host compiler fails with this error message

for some reason, the host compiler fails with this error message
/home/zampins/Devel/petsc/include/../src/mat/impls/aij/seq/aij.h(535): error: identifier "_mm512_reduce_add_pd" is undefined

This optimized C kernel is not used in the GPU classes, so it is safe to skip its declaration

PCML: support derived AIJ types on the finest grid

PCBDDC: speed up matrix assembly for sub_schurs by using VecScatter

PCBDDC: allow factoring and inverting local schur complements on GPUs

Remove MatConvert -> I prefer to error if some matrix type is not supported
Few minor improvements to prevent unneeded data tran

Merge branch 'stefano_zampini/matnest-fixes' into 'master'

Small improvements for MATNEST

See merge request petsc/petsc!2027

Merge branch 'stefano_zampini/bddc-log-approximate' into 'master'

Add logs to approximate BDDC + tests

See merge request petsc/petsc!2022

PCBDDCOrthonormalizeVecs: make number of vectors input-output

PCBDDC: added option to ignore nearnullspace for constraints

added code to propagate nearnullspace to local matrices

PCFieldsplit: use the correct MATNEST

Have to handle 64 bit integers in print statements

Addressed Barry's comments

HMG: added a test for ``-pc_hmg_coarsening_component"

HMG: added a parameter to choose which component will be used for the subspace-based coarsening algorithm
