* Rewrite the interior part of the 8-4 Kreiss-Oliger dissipation operatordiener2012-05-14
| | | | | | | | | | | to use an explicit loop instead of Fortran 90 array statements since the openmp workshare directive is not parallelized by the intel compilers. This is based on an original patch by Christian Reisswig. Do for this is only done for this operator since this is most often used in BBH simulations. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/SummationByParts/trunk@132 f69c4107-0314-4c4f-9ad4-17e986b73f4a
