The next generation of supercomputers will break the exascale barrier. Soon we will have
systems capable of at least one quintillion (billion billion) floating-point operations per …

In this article, we describe the context in which an international race towards Exascale
computing has started. We cover the political and economic context and make a review of …

Supercomputers offer new opportunities for scientific computing as they grow in size.
However, their growth also poses new challenges. Resilience has been recognized as one …

General Matrix Multiplication (GEMM) is a key subroutine in highperformance computing.
While the mainstream linear algebra libraries can deliver high performance on large and …

In this paper, we analyze the performance and energy consumption of an Arm-based high-
performance computing (HPC) system developed within the European project Mont-Blanc 3 …

The tasking model of OpenMP 4.0 supports both nesting and the definition of dependences
between sibling tasks. A natural way to parallelize many codes with tasks is to first taskify the …

Since the appearance of Docker in 2013, container technologies for computers have
evolved and gained importance in cloud data centers. However, adoption of containers in …

The ongoing effort to reach the exascale computing barrier has led to a myriad of research
and publications in the topic of alternative energy-efficient architectures, such as ARM, for …

Performance analysis tools allow application developers to identify and characterize the
inefficiencies that cause performance degradation in their codes, allowing for application …

ARM's involvement in funded international projects has helped pave the road towards ARM-
based supercomputers. ARM and its partners have collaborately grown an HPC ecosystem …
