CSEP1 Status

Introduction

Retrospective experiments of earthquake forecasts represent an important feature of the CSEP software infrastructure. They provide significant insight into the performance of earthquake forecasting models and allow scientists to evaluate the performance of forecasts on historic earthquake sequences. The CSEP1 system is designed to support retrospective forecast experiments. However, operate in serial; meaning that processing capabilities must happen sequentially. This sequential behavior is enforced within CSEP using locks that are placed on active directories during computation. The locks are used to prevent data contamination, and to prevent overwriting data by a different process.
