The rapidly growing compute demands of AI necessitate the creation new computing architectures and approaches. Tenstorrent designed its architecture (embodied in Grayskull Wormhole devices) to tackle this challenge via two fundamental synergistic first is compute-on-packets fabric that built from ground up for massive scaleout. second ability execute dynamic computation, into compiler, runtime ...

We analyse 15 XMM–Newton observations of the Seyfert galaxy NGC 4051 obtained over 45 d to determine the ultraviolet (UV) light curve variability characteristics and search for correlated UV/X-ray emission. The UV light curve shows variability on all time-scales, however with lower fractional rms than the 0.2–10 keV X-rays. On days–weeks time-scales the fractional variability of the UV is Fvar ...

Ray-tracing is a compute-intensive technique to render three-dimensional graphics and is embarrassingly parallel. There are many examples of ray-tracing applications from both academic and public domain projects. We ask if the parallelization and optimization issues are similar. This paper uses two sequential raytracing applications (POV-Ray (Persistence of Vision Raytracer) and PBRT (Physicall...

Modern GPUs with their several hundred cores and more accessible programming models are becoming attractive devices for compute-intensive applications. They are particularly well suited for applications, such as image processing, where the end result is intended to be displayed via the graphics card. One of the more versatile and powerful graphics techniques is ray tracing. However, tracing eac...

Significant advances have been achieved for realtime ray tracing recently, but realtime performance for complex scenes still requires large computational resources not yet available from the CPUs in standard PCs. Incidentally, most of these PCs also contain modern GPUs that do offer much larger raw compute power. However, limitations in the programming and memory model have so far kept the perf...

Recent GPU advances have popularized pixel-shader based techniques for per-pixel displacement mapping. An important step in the process is to compute intersection of ray with a bilinear patch approximating the displacement map. Accurate ray-patch intersection can significantly enhance the quality of rendered images. However, the increase in quality comes at a significant computation cost result...
