MONC is a highly scalable modelling tool for the investigation of atmospheric flows, turbulence, and cloud microphysics. Typical simulations produce very large amounts of raw data, which must then be analysed for scientific investigation. For performance and scalability reasons, this analysis and subsequent writing to disk should be performed in situ on the data as it is generated; however, one does not wish to pause the computation whilst analysis is carried out. In this paper, we present the analytics approach of MONC, where cores of a node are shared between computation and data analytics. By asynchronously sending their data to an analytics core, the computational cores can run continuously without having to pause for data writing or analysis. We describe our IO server framework and analytics workflow, which is highly asynchronous, along with solutions to challenges that this approach raises and the performance implications of some common configuration choices. The result of this work is a highly scalable analytics approach, and we illustrate on up to 32 768 computational cores of a Cray XC30 that there is minimal performance impact on the runtime when enabling data analytics in MONC and also investigate the performance and suitability of our approach on the KNL.
