If true, computation is performed with local jobs. MRTask.doAll(Vec, boolean) and other overloaded variants are during the computation called with runLocal set as true. Thus setting effects the main CoxPH computation only. Model metrics computation doesn't honour this setting - ModelMetricsRegressionCoxPH.concordance() computation ignores it.
