Scoping Workshop “From the Atom to the Material”

18 – 20 September 2017, CECAM-UK-JCMAXWELL, University of Cambridge, UK

The Scoping Workshop “From the Atom to the Material” that took place in Cambridge in September 2017, aimed at opening up the dialogue between modellers and industrial users with the intention to discuss and review: (i) examples of use case requirements from industry for modelling and simulation under the general objectives of ‘From the atom to the material’ and the timescales for these requirements; (ii) which of these requirements can already be fulfilled by current simulation and modelling capabilities; (iii) which of these requirements will be fulfilled by methods and technologies currently under development; and (iv) gaps in capability. The meeting was divided into themes with clear steers given to the speakers and discussion sessions in between, from which emerged a set of recommendations identified in the workshop report.

 

State-of-the-Art Workshop in Mesoscale and Multiscale Modelling

29 May – 1 June 2017, CECAM-IRL, University College Dublin, IRL

The 3 day State-of-the-Art Workshop in the E-CAM Meso and Multiscale Modelling Work Package (WP4)  brought together 44 participants, and focused on the identification of the (i) current challenges; (ii) existing software solutions and their limitations; and the (iii) need for further development of meso- and multiscale methods and codes. Given the spirit of the workshop, focused on a survey of the state of the art, the main outcomes of the discussions aimed at setting the stage for promoting further development and creating the best research environment. The event recognized the needs to advance in the establishment of mesoscopic models and their proper calibration to convert them into quantitative predictive tools. The event also served to agree that in the next four years we can expect a consolidation of different mesoscopic methods developed over the last ten years and a more systematic analysis to be able to combine them with molecular methods.

 

State-of-the-Art Workshop in Reaction Coordinates from Molecular Trajectories

29 August – 2 September 2016, Lorentz Centre, Leiden, NL

Short description: The 5 day workshop in the E-CAM classical molecular simulation work-package brought together 31 participants, and focused on the identification of reaction coordinates and the construction of reliable models from atomistic simulation data, such as nucleation at phase transitions, drug binding, protein-protein interactions, protein folding, association, and self-assembly. The computational methodologies discussed are relevant to fields ranging from physics and chemistry, to materials science and molecular biology. Several issues were discussed and partially resolved, including for instance, how to use machine learning to find collective variables and reaction coordinates. A series of community needs for methods and software tools were identified.

 

State-of-the-Art Workshop in Electronic Structure

12 – 14 September 2016, Cranage Hall, UK

Short description: The 3 day workshop in the E-CAM electronic structure work-package brought together 23 participants. Density functional theory is now a mature technology that is increasingly finding application industrially. Industrial use demands accuracy, which is now being addressed by validation and verification exercises such as the D Codes Project. A recurring theme of the meeting was the importance of having well specified error bars, and clear definitions of applicability of the different methods. It also was clear that dynamics, multi-scale modelling and finite temperature effects remain challenging topics. To expand the applicability of DFT, and post DFT theories, advanced techniques from computer science are already being applied and can be expected to play an increasing role, these include not only the use of massively parallel hybrid CPU/GPU hardware, but also efficient strategies based on machine learning.

 

State-of-the-Art Workshop in Quantum Dynamics

6 – 10 June 2016, EPF Lausanne, CH

Short description: The 5 day workshop in the E-CAM quantum dynamics work-package brought together 40 participants. New methodologies or major enhancement of existing methods of quantum dynamics were identified including: ring polymer molecular dynamics at the cost of classical molecular dynamics, which paves the way for the inclusion of quantum effects in condensed phase reactions, and in biological processes. Quantum dynamical simulations are increasingly relevant to industry, including hardware design (e.g. coherence and interference effects for quantum control or design of q-buts), pharmaceuticals (e.g. tunneling in enzymatic reactions), and energy production or storage. In the context of E-CAM, new simulation methods and algorithms for quantum computing are being developed with IBM, with similar collaborations involving other participants. Surface hopping and multiple spawning are methods of choice to simulate excited-state dynamics of molecular systems. Applications of these techniques to dyes and emitters have been reported, and brought insight to the design of molecules for various applications such as dye solar cells (e.g. collaborative projects with Dyesol, BASF) or organic light emitting diodes (with BASF, Novaled). Excited state, and in particular non-adiabatic dynamics is potentially interesting also for pharmaceutical companies, for example, to prevent photo damage leading to skin cancer.

 

PRACE/E-CAM Spring School on Molecular and Atomic Modelling

16 – 20 May 2016, UCD, Dublin

Short description: This workshop, which attracted 32 participants from across Europe, focused on parallel programming models, emerging HPC platforms and a range of scalable molecular dynamics and electronic structure codes. Among the lecturers there were representatives from the DL_POLY, CP2K and GROMACS, Quantum Espresso, SIESTA and ASE developer communities as well as PRACE application performance experts.
