Tpetra: gap sequence in shell sort
Created by: jhux2
In the Tpetra shell short, the gap sequence is currently {1,2,4,8,...}. This could lead to poor performance in some cases. (See bugzilla bugs 4301 and 4244.) Similar gap sequences were partially fixed in Epetra.
I haven't encountered any problems with shell sort in Tpetra, so this issue merely serves to record the matter.
