Presentation
Exploiting Data Compression and Low Precision for Exascale Fusion Turbulence Simulations
DescriptionFuture exascale systems will feature unprecedented computing power with over 10^18 FLOPS, provided by thousands of heterogeneous computing nodes. To fully harness such potential, applications must scale effectively and efficiently utilize these computing architectures.
Many performance losses on large HPC systems originate from inefficiencies in data movement.
On exascale systems, the involved data set size also increases, leading to challenges in (a) migrating data through memory hierarchies, (b) communicating data between distributed memory components, and (c) storing data in file systems.
This poster shows the ongoing effort in the DaREXA-F project and its goal to address these issues in the plasma turbulence code GENE, by measures such as (a) mixed precision and the usage of novel data formats, (b) data compression, and (c) utilizing new network hardware.
We present our current findings in the areas of mixed-precision and lossy data compression for efficient computation without a reduction in accuracy.
