File IS-ENES2_D9.3_Assessment report on Autosubmit, Cylc and ecFlow
D-9.3, “Assessment report on Autosubmit, Cylc and ecFlow”, is a deliverable due in month 36, ahead of the deliverable D-9.6 “Multi-model multi-member (M4) high resolution (HR) Earth System Model (ESM) ensemble performance analysis”. In the context of work package 9, IC3/BSC in collaboration with the Met Office, have set up three tools to design workflows and monitor experiments: Autosubmit, Cylc and ecFlow. The three scheduling and submission systems have been tested and evaluated with regard to the suitability for M4 HR experiments. GloSea5 operational seasonal forecast system and EC-Earth3 decadal hindcast have been prototyped with several workflow configurations in order to compare the differences and assess the suitability of the three tools for M4 HR experiments.

File IS-ENES2_D9.4_CDI-pio & XIOS I/O servers compatibility with HR climate models
I/O performance is likely a leading constraint to efficient operation of High Resolution Earth System Model (HR ESM) simulations. The I/O libraries CDI-pio (jointly developed by MPG and DKRZ) and XIOS (developed at IPSL) were implemented and tested with several components of the earth system models used in the present IS-ENES2 work-package 9. CDI-pio was evaluated with the atmospheric model ECHAM6 and XIOS with the atmospheric model ARPEGE-Climat and the ocean model NEMO. Both CDI-pio and XIOS2 I/O libraries prove their capacity to efficiently manage high resolution model output.

File SIS package IS-ENES2_D9.5_CDO performance analysis
The computational performance of the CDO (Climate Data Operators) is investigated in the context of the M4HR (Multi-model multi-member high-resolution) demonstrator developed in JRA1. A detailed performance analysis focussed on the disk transfer rates (read and write operations) of the CDO and shows no indication of performance bottlenecks in the post-processing workflow.

File IS-ENES2_D9.6_Multi-model multi-member integrated simulation: computing performances of a demonstrator and other single high-resolution climate models
A set of scripts and configuration files necessary to launch an ARPEGE-NEMO/EC-Earth multi-model multi-member high-resolution (M4-HR) experiment are developed and the existing single model workflow adapted. The Autosubmit tool ensures a remote management of simulations performed on the BSC MareNostrum III supercomputer. The pre-existing single model launching scripts are easily parametrised to let Autosubmit cope with difficulties related to remote connection and multi-member simulation handling. The new developments include a final analysis that delivers computational metrics that helps to evaluate models and whole M4-HR experiment performances.

File IS-ENES2_D10.1_Documentation on benchmarking framework_Submitted Version
This deliverable outlines our strategy on how to implement a technical and organisational framework for development, distribution and evaluation of application benchmarks for Earth System Modelling. The structural components of the framework are (1) Service platform “Performance Analysis for Earth System Modelling”, (2) Earth System Model Benchmark Suite containing climate application benchmarks of varying complexity, (3) Set of common performance metrics, (4) Measurement and evaluation tools, and (5) Central benchmark repository.

File IS-ENES2_D10.2_Interim report on status of benchmark suite
This deliverable describes the current development status of the ENES Benchmark Suite, a collection of real application benchmarks used to model Earth System. The suite is assembled from applications of varying complexity ranging from simple computational and communication kernels to fully coupled Earth System Models (ESMs). The focus is here set on description of already available benchmarks: CMCCC-CESM-NEMO, EC-EARTH, IPSLCM and MPI ESM1. The Redmine project management tool is employed to ensure the availability of up-to-date benchmarks and performance data.

File IS-ENES2_D10.3_Report on benchmark suite for evaluation of coupling strategies
This document describes the work done to develop a first version of a community coupling technology benchmark. Today, stand-alone components running on 4 different grids and coupled test-cases based on components running on the regular latitude-longitude grid and using either the OASIS3-MCT, OpenPALM, ESMF, MCT or YAC coupling technologies are publicly available. As a proof of concept, these coupled test cases were run in different configurations on three different platforms: Bullx at CINES in France, Cray XC40 at the UK MetOffice, and the Broadwell partition of Marconi at CINECA in Italy. The coupled components exchange coupling fields defined on grids of different sizes decomposed in parallel partitions with different aspect ratios and different orientations. The timings obtained for the coupling initialisation and coupling exchanges for the different tests are detailed, primarily to demonstrate the versatility of this benchmarking environment. However, these first results are not yet suitable to draw any firm conclusions on the relative performance of the coupling technologies used.

File application/x-troff-ms IS-ENES2_D10.4_Report on the suite of base benchmarks and analysis of performance on available platforms
This report describes the final status of the ENES Benchmark Suite at the end of the IS-ENES2 project. The suite is assembled from applications of varying complexity ranging from computational and communication kernels to fully coupled Earth System Models (ESMs). The Redmine project management tool is employed to ensure the availability of up-to-date benchmarks and performance data. The HPC vendors’ feedback suggests that the prepared benchmarks are useful and necessary for efficient collaboration between climate modelling community and HPC system providers.

File IS-ENES2_D11.1_ENES Data Activities: Delivery Plan
The breakdown of IS-ENES2 data work packages (WP5, WP8, and WP11) into three themes: data, metadata, and impacts is described. The relationships within and between these themes, and between the themes and major external activities are described, as are the concomitant dependencies, particularly on timing. We provide a summary of how these relationships and the IS-ENES2 activity roadmap will be managed.

File IS-ENES2_D11.2_Report on Climate4impact portal, version 1_Submitted Version
This report describes the functionality and commissioning of version 1 of the CLIMATE4IMPACT portal, including its acceptance into the operational services run under SA2. This release of the portal will be based on the prototype deployed in ISENES1. It allows users to explore data held at distributed archive nodes using a range of plotting options. In addition to the services deployed in the prototype, plotting of time-series is made available.
