A new Flyspray task has been opened.  Details are below. 

User who did this - Bernd Flemisch (bernd) 

Attached to Project - DuMuX
Summary - Get rid of "self-written" parallel linear solvers
Task Type - Feature Request
Category - General
Status - New
Assigned To - Bernd Flemisch
Operating System - Unspecified
Severity - Low
Priority - Normal
Reported Version - SVN
Due in Version - 2.9
Due Date - Undecided
Details - In dumux/linear/boxlinearsolver.hh, there are several linear solver 
backends which use "self-written" infrastructure for parallel runs from the 
files borderindex.hh, domesticoverlapfrombcrsmatrix.hh, 
elementborderlistfromgrid.hh, foreignoverlapfrombcrsmatrix.hh, 
globalindices.hh, overlapping...hh, vectorexchange.hh, 
vertexborderlistfromgrid.hh.

Since the parallelism is restricted to box, the iteration counts deteriorate 
with growing process numbers, the code is hard to maintain or to generalize, 
and we have the general / rather robust / mostly upstream-maintained 
AMGBackend, I propose to get rid of boxlinearsolver.hh and the infrastructure 
files.
