在社区代码FLASH- X中使用AMR的拉格朗日粒子网格的检查点/重新启动

Checkpoint/Restart for Lagrangian particle mesh with AMR in community code FLASH-X

Rajeev Jain, Klaus Weide, Saurabh Chawdhary, Thomas Klostermann

摘要:

在这项工作中,我们提出的设计决策和优势,实现跨网格格式检查点重新启动社区代码FLASH-X。AMReX和Paramesh是FLASH-X开发和支持的两种AMR网格格式。我们还强调了现有的HDF 5 I/O检查点写入的强扩展和弱扩展研究,以及利用异构计算架构提高I/O性能的新想法和结果(在演讲中介绍)。

英文摘要:

In this work we present the design decisions and advantages for accomplishing cross mesh format checkpoint-restart in community code FLASH-X. AMReX and Paramesh are the two AMR mesh formats developed and supported by FLASH-X. We also highlight strong and weak scaling study of existing HDF5 I/O checkpoint writing along with new ideas and results (presented during talk) for utilizing heterogeneous compute architectures for improved I/O performance.
