What's a model restart?| Excerpt |
|---|
A restart allows the model to continue a forecast with a succession of individual runs, each one starting where the other one left off. e.g. running an extended forecast of 100 days with 5 separate runs of 20 days each. |
A restart will always be exact, that is, the results of the restarted forecast should always match a single run of the model for the same total length (assuming all settings remain the same). This page describes how to configure and use the model restart facility. n.b. the restarted run must always have the same parallel decomposition (TASKS x THREADS) |
