* CycleClock: define CycleClock_Setup() without HAVE_TICK_COUNTERFrank Löffler2013-10-11
| | | | | | | Define a dummy CycleClock_Setup() routine for Cactus to call from the scheduler. Without this, the linker will rightfully complain about the missing symbol if the architecture doesn't have counters (HAVE_TICK_COUNTER isn't defined).

* CycleClock: Determine elapsed time via integer arithmeticErik Schnetter2012-12-31
| | | | Determine elapsed time via integer arithmetic, which may be more accurate that double precision arithmetic.

* CarpetLib, CycleClock: Move cycle counting clock into its own thornErik Schnetter2012-12-21
New thorn CycleClock, mostly taken out of CarpetLib. This thorn provides an (almost) cycle-accurate clock, taken from FFTW. This clock is both directly accessible, and is also wrapped in a Cactus clock. Note: Applying this commit will require adding thorn CycleClock to thorn lists and parameter files.
