The Barcelona Supercomputing Center (BSC) will participate in the DEEP-EST project kicked off today at the Juelich Supercomputing Center (Germany). Its aim is to create a Modular Supercomputer Architecture (MSA) tailored to the complexity of state-of-the-art simulation codes and the growing range of tasks at computing centres. BSC has been involved as a partner of the predecessor projects DEEP and DEEP-ER. In this third edition of the project called DEEP-EST, the objective is to develop a prototype by 2020 that combines different computing modules according to the building-block principle and plans to include an additional new module suitable for data-analytics workloads.
“BSC has been involved in the three editions of the DEEP Projects. In this third project phase, we will contribute to enhance the system software stack (programming models, job scheduling and performance tools) to exploit the modular architecture of DEEP-EST prototype and measure the benefits that it brings for application end-users and operators of compute infrastructure”, says Viçenc Beltran, BSC Researcher of the Computer Sciences Department. BSC will enhance the programming environment developed in the DEEP/-ER projects to support the heterogeneous MSA and its highly dynamic workloads. In particular, BSC will be further developing its OmpSs programming model whose offloading features (developed in DEEP and DEEP-ER projects) will be integrated with the job scheduler to support efficient execution of evolving and malleable applications on MSA systems.
Furthermore, BSC programming model and modular-aware job scheduler will be used to validate the modular concept, while BSC job scheduler simulator and performance analysis, modelling and prediction tools (Extrae, Paraver and Dimemas) will be used to extrapolate performance, scalability and energy efficiency of the DEEP-EST prototype.
