Ascent

Description

Ascent is a many-core capable flyweight in situ visualization and analysis infrastructure for multi-physics HPC simulations.

The Ascent in situ infrastructure is designed for leading-edge supercomputers and supports both distributed-memory and shared-memory parallelism. Ascent can take advantage of computing power on conventional CPU architectures and on many-core architectures such as NVIDIA and AMD GPUs. Further, it has a flexible design that supports the integration of new visualization and analysis routines and libraries.

Impact, Sustainability, and Quality

Property	State
Impact	Ascent is integrated with several DOE applications, including WarpX, Nyx, and AMR-Wind. It is deployed at all major DOE computing facilities and is used daily for analysis and visualization.
Sustainability	Ascent's fundamental capabilities are widely used, and it has a fairly sustainable DOE NNSA funding stream. The support for ASCR computing facilities and applications is dependent on DOE funding.
Quality	Ascent has well-established quality metrics, software, and testing processes.
