The ALPINE/zfp ECP Effort: Unleashing Exascale Visualization and Analysis
Explore the joint ALPINE/zfp ECP effort and its role in revolutionizing exascale visualization and analysis.
The ALPINE project and the zfp project are two key components of the ECP Data and Visualization efforts. ALPINE focuses on delivering exascale visualization and analysis algorithms, while zfp addresses the compute and I/O mismatch through floating point compression algorithms.
ALPINE's goal is to provide insight from massive data through general yet exascale-capable visualization and analysis algorithms. This project enables scientists to extract valuable insights from simulations by developing in situ infrastructures that deliver visualization, data analysis, and data reduction capabilities while the simulation is running. By shifting the analysis paradigm from post hoc to in situ, ALPINE eliminates the need for time-consuming postprocessing and enables real-time analysis.
On the other hand, zfp introduces a change in mindset when it comes to compression. By employing lossy compression algorithms, zfp allows users to define error bounds and discard the least significant floating point data bits. This approach not only reduces the amount of data that needs to be stored but also enables applications to directly use the compressed data, thanks to fast and hardware-accelerated algorithms.
