Extreme-scale Data and Computing

…tackles the new fundamental challenges for computer science and engineering research, posed by the unique combination of Modelling and Simulation with Health Data Science and Health Informatics. The computational and data processing needs of Sano research will push the boundaries of current state-of-the-art infrastructures for AI, HPC, big data and cloud computing. This includes alignment of traditional HPC systems with big data analytics and ML/AI workloads, using CPU, GPU, many-core, hybrid, virtualized and containerized environments with the computational needs of systems required to deliver patient-specific care at timescales appropriate for clinical use. Moreover, health data science will benefit from novel approaches in distributed computing and security research, such as Federated Learning, Blockchain, Differential Privacy or Encrypted Computation, which can be applied to medical data in a secure and privacy-conscious manner.

New developments in computer hardware, programming models, cloud computing and emerging services will influence development, deployment and execution of computational and AI models at extreme scale, requiring constant evaluation of new technologies and platforms, experimenting with novel approaches, and prototyping new solutions. Development of systems operating in clinical, research, HPC, Big Data/AI environments will require novel, transparent techniques, and the delivery of state-of-the-art in health data science and in-silico techniques will require exascale computing resources. Sano will become a driver for developments within EU-level HPC and cloud initiatives, including PRACE and EuroHPC.

Current Projects

The In Silico World project aims at accelerating the uptake of modelling and simulation technologies used for the development and regulatory assessment of medicines and medical devices, by lowering seven identified barriers: development, validation, accreditation, optimisation, exploitation, information, and training.

Computer models informed by experimental data enable us to test hypotheses and make predictions, significantly streamlining the research and development cycle relative to trial and error. When it comes to medicine, experimentation relies on biological samples ranging from cultured cells to whole animals, so increased reliance on modelling has additional benefits. Harnessing Big Data and tremendous advances in computing power could pave the way to minimising and eventually eliminating the need for anything other than in silico ‘experimentation’ in medical research and development.

The consortium will use an advanced simulation environment developed by Sano to address the needs for scalability and efficiency of the solutions developed in the project. Such environment provides access computation and storage resources in local and the main European e-infrastructures and commercial cloud services. Moreover, Sano works on performance, scalability and cost efficiency of the advanced simulation models running at extreme scale.

More about the project:

  • MSc Project 
  • Although federated learning is a promising technique for analysis of medical images, as it may solve some security and privacy issues related to distributed data access, there is still a need to evaluate this technique in large-scale experiments in a distributed environment such as cloud infrastructure. 

The goal of the thesis will be to run large-scale experiments with federated learning on medical image classification tasks. We plan to use public datasets such as chest X-ray images, coming from multiple sources (countries, hospitals), and existing distributed machine learning frameworks. As the computing infrastructure, a public cloud and PL-Grid infrastructure will be used. Various metrics related to the distribution of data, its granularity and partitioning will be investigated, to understand their impacts on the both the efficiency of the learning process and the performance of the infrastructure. It will be also possible to extend the study to assess the impact of possible attacks and their mitigation strategies. 

  • MSc Project 
  • Federated learning is a technique which allows training machine learning models in a distributed way without transferring the data from its source. It has thus potential applications in medical image analysis, where privacy and security issues are of great importance. Although there are examples of using federated approaches to analysis of medical images, there is still need for research in this area and for experiments in distributed environment. 

The goal of the thesis will be to apply federated learning techniques to the problem of medical image segmentation. We plan to use public datasets such as echocardiography, coming from multiple sources. The analysis will be performed using distributed computing frameworks such as Flower or FedML, using distributed computing infrastructures such as PL-Grid or a public cloud service. In addition to evaluation of the learning process, the goal will be also to evaluate the performance of distributed computing environment. Further study will include also possible attacks and security of the developed solution. Other types of data and machine learning tasks can be considered for comparison as well.
