Progress in data transfer: an essential aspect of the DeepRain project is the large amount of data used for training and evaluation of machine learning methods. A total of over 430 terabytes of data are currently being transferred from the German Weather Service to Forschungszentrum Jülich to be used on JSC supercomputers for deep learning. Today, the 100th terabyte was successfully transferred and integrated into the storage systems at JSC. This is an important milestone, as enough data is now available to carry out the first meaningful deep learning and analyses.
