Device/GPU side sorting in OpenMP (ie, with #prama omp target)

I ve been playing a bit with OpenMP recently in particular, with the pragma omp target based device offloading that OpenMP 5.0 and newer are offering. Overall I really like it, but one of the things I found is that whereas classical GPU languages have lots of helper libraries for common things like sorting, this Continue reading Device/GPU side sorting in OpenMP (ie, with #prama omp target)

Update: OWL now (finally) hosted on https://github.com/NVIDIA/owl

I m aware that not everybody does (yet) know what OWL actually is, but for those that do, and for those: yes, I know I have to write a blog article about OWL at some point in time to introduce it but this is not the blog post that ll do this. For those that do Continue reading Update: OWL now (finally) hosted on https://github.com/NVIDIA/owl

Quick Update: Just Updated github ‘optix7course’

For a while now I ve been telling everybody that my original optix7course repo on github (ie, https://github.com/ingowald/optix7course) is a bit deprecated, and everybody should instead look at OWL (which since last week can be found at a new location, at https://github.com/NVIDIA/owl, but that s a topic for another post ), but since that repo still has a Continue reading Quick Update: Just…

Multi-GPU (but non-MPI) Data-Parallel Rendering in Barney/ANARI

This article is about a capability and in particular, about the how do you actually use that that i recently added to Barney, namely, to do data-parallel multi-GPU rendering through Barney s ANARI interface layer. This is not a comprehensive discussion about barney, or data-parallel rendering in Barney, but enough people asked about this Continue reading Multi-GPU (but non-MPI) Data-Parallel…

New release: pynari 1.2.8

After a lot of fixed, pynari 1.2.8 was finally released earlier this week. Biggest update: Milan Jaros (https://www.researchgate.net/profile/Milan-Jaros-3) provided some first interactive samples using a 3D volume viewer he wrote: Other updates:

“First light” of Barney Rendering of Drosophilia Brain Data

I ll have to write a bit more later on the how of it, but for now, just a quick first light of barney rendering the latest Drosophilia Brain data set (using four H100 GPUs). That droso data set is from the Virtual Fly Brain project https://www.virtualflybrain.org/, and was recently used by/featured in multiple major articles Continue reading First light of Barney Rendering of Drosophilia Brain…

Funny Image of the Day…

One of the best things about working in graphics is that at least some of the bugs one encounters are in some way, shape, or form funny. I ve always liked the accidental art that often comes out of this, and had my fair share of that myself and every time I tell Continue reading Funny Image of the Day

pynari 1.1 coming up: Support for system-level ANARI installs, and CPU fallback

Good news; getting closer to the next version of pynari: Feedback to 1.0 was overwhelmingly positive, but two things stood out: First, there seems to be some demand for having a CPU-fallback for the kind of hardware that doesn t have any CUDA capable GPUs (MacBooks in particular seem to be en vogue here :-/). I Continue reading pynari 1.1 coming up: Support for system-level ANARI installs, and CPU…

pynari (Ray Traced ANARI rendering in Python) – First Light!

I haven t written much for a while partly because I was too busy, partly because some of the stuff i worked on I couldn t write about, and mostly, because much of the stuff that I could in theory write about wasn t exactly ready enough to do so. Much of that is now slowly falling Continue reading pynari (Ray Traced ANARI rendering in Python) First Light!

New Paper Preprint: Data Parallel Ray Tracing in Object Space

(sorry for the delay, this is a bit outdated this was apparently stuck in my Draft folder, and never sent out ) Finally . I can share this paper. I m actually super-happy that this paper is finally out I ve now been working on this particular problem/idea on and off for at Continue reading New Paper Preprint: Data Parallel Ray Tracing in Object Space
