Detailed Description

internal timer

measures the computational and communication total times and allso at each multigrid level node 0 the writes average time, min and max ( accros active ranks for each level)

If the environment variable DL_MG_TIMER_MG_LEVELS is defined times for multigrid components (per thread) are collected
