#1744: Carpet-Accelerator typo for filling timelevels

 Priority:  unset                    |   Milestone:                     
Component:  Carpet                   |     Version:  development version
 Keywords:  accelerator              |

 In Carpet/src/Cycle.cc (current master branch): in function
 FillTimeLevels, line 282 reads

 {{{
 278             if (have_accel) {
 279               const CCTK_INT on_device = 0;
 280               Accelerator_NotifyDataModified
 281                 (cctkGH,
 282                  &vis.front(), &rls.front(), &rls.front(), vis.size(),
 283                  on_device);
 284             }
 285           }
 286           break;
 }}}

 The line should read

 {{{
 282                  &vis.front(), &rls.front(), &tls.front(), vis.size(),
 }}}

 as the second-to-last argument of Accelerator_NotifyDataModified should
 correspond to timelevels.  Failing to pass this correctly can lead to
 std::out_of_range errors as Accelerator tries to access locations that do
 not exist in its "mem" structure.
