The Barcelona Supercomputing Center (BSC) was established in 2005 and serves as the Spanish national supercomputing facility. The center hosts MareNostrum4, one of the most powerful supercomputers in the world. The mission of BSC is to research, develop and manage information technologies in order to facilitate scientific progress. BSC strives to be a first-class research centre in supercomputing and in scientific fields that demand high performance computing resources such as Life and Earth Sciences and Computer Applications in Science & Engineering.

BSC will contribute to the  DEEP-EST project by leading the work package “Benchmarking and modelling” by experts of the Computer Science Department. The team will evaluate the DEEP-EST prototype and measure the benefits that it brings for application end-users and operators of compute infrastructure. BSC’s performance tools and modelling infrastructure (BSC efficiency model) are the basis of this task: Extrae/ Paraver measure the use of compute and memory resources, the interconnect, and the I/O subsystem, while Dimemas provides predictions for architecture or application modifications and the BSC efficiency model yields accurate scaling predictions (as already demonstrated in the DEEP/-ER projects). BSC tools can automatically identify different phases of applications, and this capability will serve to build specific models for each of the phases, thus improving precision compared to conventional approaches that treat applications as single unit.

Furthermore, BSC will also be involved in the further extension of the "programming environment” that has been developed in the DEEP and 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) will be integrated with the resource manager and job scheduler to support efficient execution of evolving and malleable applications on MSA systems.
