From Edge to HPC: Investigating Cross-Facility Data Streaming Architectures
In this paper, we investigate three cross-facility data streaming architectures, Direct Streaming (DTS), Proxied Streaming (PRS), and Managed Service Streaming (MSS). We examine their architectural variations in data flow paths and deployment feasibility, and detail their implementation using the Data Streaming to HPC (DS2HPC) architectural framework and the SciStream memory-to-memory streaming toolkit on the production-grade Advanced Computing Ecosystem (ACE) infrastructure at Oak Ridge Leader…

Ilford HP5 Plus 400 (FF) English Alt Text: A black and white image displays a close-up view of multiple transparent glass jars arranged in neat rows and columns. The jars are identical in shape and size, creating a symmetrical and repetitive pattern. Reflections and shadows on the glass surfaces add depth and texture, while the monochrome palette emphasizes form over color. The composition has an abstract quality, inviting viewers to focus on geometry, light play, and the subtle variations in …
Ilford HP5 Plus 400 (FF) English Alt Text: A close-up black and white photo shows plant leaves and stems in sharp focus, with a blurred architectural structure in the background. The leaves are irregularly shaped, with holes and jagged edges, possibly from insect damage. The background features a slanted roof and window-like shapes, suggesting a building. The interplay of light and shadow creates a moody atmosphere, emphasizing texture and depth. The contrast between the organic foreground and…
Ilford HP5 Plus 400 (FF) English Alt Text: A black and white photograph captures an elevated pedestrian bridge spanning a busy urban street. The bridge features vertical railings and an arched support structure above, creating a rhythmic pattern. The perspective is from below, looking up through the railings, which adds depth and layering to the composition. Below the bridge, numerous cars and pedestrians fill the street, suggesting a bustling city environment. The contrast between the rigid g…
Ilford HP5 Plus 400 (FF) English Alt Text: A black and white photograph captures a sunlit indoor hallway with tiled flooring. A radiator is mounted beneath a window, and a fire extinguisher stands near a gated door in the background. Sunlight streams through the window, casting sharp, geometric shadows on the floor, including a serrated edge pattern likely caused by blinds. The image emphasizes architectural details and the dramatic contrast between light and shadow, creating a quiet, contempl…

Ilford HP5 Plus 400 (FF) English Alt Text: A black-and-white photograph of a modern architectural interior. Tall vertical windows with metal frames allow sunlight to stream in, casting sharp shadows on rough concrete walls and beams. The space feels industrial and geometric, with strong lines and textures. Recessed ceiling lights are arranged in neat rows, adding to the clean, structured aesthetic. The interplay of light and shadow emphasizes the raw materials and creates a dramatic, contempla…
Ilford HP5 Plus 400 (FF) English Alt Text: A black-and-white photo taken from a low angle, looking up at the sky. On the right, a building with curved and angular architectural features is partially visible. Tree branches and leaves form dark silhouettes across the frame, adding depth and framing the scene. The sky is faintly speckled with light, possibly stars. The image evokes a quiet, introspective mood through its contrast of nature and structure. 中文替代文字： 这是一张黑白照片，从低角度仰望天空。画面右侧是一座建筑，轮廓曲线与…
Ilford HP5 Plus 400 (FF) English Alt Text: A black-and-white cityscape showing contrast between old and new. In the foreground, a traditional tiled roof with weathered texture suggests historical architecture. A leafy tree partially obscures the view. In the background, sleek high-rise buildings tower above, representing modern urban development. The image captures the coexistence of heritage and progress in a single frame. 中文替代文字： 这张黑白城市风景照展现了传统与现代的对比。前景是一座传统瓦屋顶，瓦片斑驳，透露出历史的痕迹。右侧有一棵树，枝叶茂密，部分遮…
Ilford HP5 Plus 400 (FF) English Alt Text: A black-and-white photograph of a bustling city street. Mid-rise buildings with balconies line the right side, while an elevated structure casts shadows on the left. Cars, scooters, and pedestrians fill the scene, some carrying umbrellas. A tall streetlamp stands prominently in the foreground. The image captures the energy and density of urban life, with layered architecture and movement throughout. 中文替代文字： 这张黑白照片描绘了一个繁忙的城市街景。右侧是一排带阳台的中高层建筑，左侧则有一座高架结…

The LCLStream Ecosystem for Multi-Institutional Dataset Exploration
We describe a new end-to-end experimental data streaming framework designed from the ground up to support new types of applications -- AI training, extremely high-rate X-ray time-of-flight analysis, crystal structure determination with distributed processing, and custom data science applications and visualizers yet to be created. Throughout, we use design choices merging cloud microservices with traditional HPC batch execution models for security and flexibility. This project makes a unique con…
