Innovation Solution
A scientific visualization system utilizing an AI/ML component, DPSL, and dynamically negotiating client-server visual rendering, with a hierarchical storage system, enables flexible execution on diverse compute resources, supporting in-situ or in-transit visualization and client-side or server-side rendering, and employs a portable performance feature through hardware abstraction to optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cloud-based virtualized computing resources are used for scientific visualization, then resource flexibility and scalability are improved, but network latency and bandwidth variability increase
Solution Approach 1:
The visualization system is segmented into multiple independent components: a cloud-based virtualized computing environment for data processing and a client-side rendering environment for visualization display. This segmentation allows each component to operate optimally in its respective domain, with the cloud handling compute-intensive tasks and the client handling rendering tasks, thereby reducing network latency while maintaining resource flexibility.
Solution Approach 2:
A portable performance layer acts as an intermediary between the heterogeneous cloud resources and the visualization application. This layer abstracts the complexity of diverse cloud resources and optimizes data transfer and processing, mediating between the cloud's resource flexibility and the client's rendering requirements to minimize network latency.
2Adaptability or versatility
If heterogeneous cloud resources are allocated dynamically, then resource allocation flexibility is improved, but system complexity increases
Solution Approach 1:
The portable performance layer provides a universal interface that works across multiple types of cloud resources (different hardware architectures, virtualization platforms, and cloud providers). This multi-functional layer handles resource allocation, data transfer, and performance optimization uniformly, simplifying the system architecture while maintaining high flexibility in resource allocation.
Solution Approach 2:
The system creates virtualized copies of cloud resources through the portable performance layer, allowing the visualization application to interact with standardized virtual resource interfaces rather than direct physical hardware. This copying approach abstracts the heterogeneity of underlying resources, reducing system complexity while enabling flexible dynamic allocation.
3Ease of operation
If visualization rendering is performed on client devices, then user interactivity is improved, but client hardware requirements increase
Solution Approach 1:
The system performs partial rendering on the client side for user interaction while offloading heavy computational tasks to the cloud. The portable performance layer manages this partial action by handling only the essential rendering operations that require user interactivity, while complex data processing and preparation are performed excessively on the cloud side, ensuring smooth client-side interaction without requiring high-end hardware.

AI summary
A scientific visualization system includes a plurality of components configured to provide visualization of filtered results of physical simulation software code (e.g., simulations) executing on virtualized resources (e.g., compute, memory and storage resources) of a cloud-based, virtual data center (server) computing environment. The scientific visualization system is further configured to render visualization images of the filtered simulation results for subsequent display at a client computer (client), or in part visualized at the client, such as a user interface browser of the client. Filtering of the simulation results and rendering of the images may be performed using visualization analysis software executing on the server of the computing environment, although rendering of the visualization images may alternatively be performed either on the server (server-side rendering) or client (client-side rendering).
