trace broken in parallel operation? #631

Closed landroni closed 6 years ago

landroni commented 6 years ago

When using trace = TRUE at the same time as stepwise = FALSE, parallel = TRUE, I notice that the list of ARIMA models considered is not being reported: auto.arima(euretail, stepwise = FALSE, trace = TRUE, parallel = TRUE, num.cores = 1)

Is trace expected to work in parallel = TRUE mode?

(Using forecast_8.2.)

I've added a message to make this clearer, currently tracing auto.arima paths in parallel is not supported.
