Software pipelining is an essential optimization for accelerating High-Performance Computing(HPC) applications on CPUs. Modern CPUs achieve high performance through many-core and wide SIMD instructions. Software pipelining is an optimization that ...

The adoption of ARM processor architectures is on the rise in the HPC ecosystem. Fugaku supercomputer is a homogeneous ARM-based machine, and is one among the most powerful machine in the world. In the programming world, dependent task-based programming ...

High-performance computational kernels that optimally exploit modern vector-capable processors are critical in running large-scale drug discovery campaigns efficiently and promptly compatible with the constraints posed by urgent computing needs. Yet, ...

ARM-based CPU architectures are currently driving massive disruptions in the High Performance Computing (HPC) community. Deployment of the 48-core Fujitsu A64FX ARM architecture based processor in RIKEN “Fugaku” supercomputer (#2 in the June 2023 Top500 ...

The engineering samples of the NVIDIA Grace CPU Superchip and NVIDIA Grace Hopper Superchips were tested using different benchmarks and scientific applications. The benchmarks include HPCC and HPCG. The real application-based benchmark includes AI-...

Arm-based system in HPC are a reality since more than a decade. However, when a new chip enters the market always implies challenges, not only at ISA level, but also with regards to the SoC integration, the memory subsystem, the board integration, the ...

At the Supercomputer System of Academic Center for Computing and Media Studies Kyoto University, the fourth-generation Xeon (code-named Sapphire Rapids) is employed. The system consists of two subsystems—one equipped solely with high-bandwidth memory, ...

This paper proposes an automatic MPI ABI (Application Binary Interface) translation library builder named MPI-Adapter2. The container-based job environment is becoming widespread in computer centers. However, when a user uses the container image in ...

Intel oneAPI is a programming framework that accepts various accelerators such as GPUs, FPGAs, and multi-core CPUs, with a focus on HPC applications. Users can apply their code written in a single language, DPC++, to this heterogeneous programming ...

Load balancing at both the process and thread levels is imperative for minimizing application computation time in the context of MPI/OpenMP hybrid parallelization. This necessity arises from the constraint that, within a typical hybrid parallel ...

In the area of high-performance computing (HPC), it is expected to extract extreme computing performance using a highly optimized framework without even common OS APIs and frameworks for personal desktops. However, this makes the development cost higher ...

Traditional steelmaking is a major source of carbon dioxide emissions, but green steel production offers a sustainable alternative. Green steel is produced using hydrogen as a reducing agent instead of carbon monoxide, which results in only water vapour ...

We proposed an implementation for surfactant transport simulations in gas-liquid two-phase flows. This implementation employs a tree-based interface-adapted adaptive mesh refinement (AMR) method, assigning a high-resolution mesh around the interface ...

Energy consumption plays a crucial role when designing simulation studies. In this work, we take a step towards modelling the relationship between statistical error and energy consumption for molecular and molecular-continuum flow simulations. After ...
