A second test release of my texture viewer is available, now:
Array textures (2D and cubemaps) are supported
- Integer textures are displayed in a (more) useful way
- Color channels can be easily swizzled by the user
- … if that's not enough, the fragment shader source can be edited in the program

#AMD splits #ROCm toolkit into two parts – ROCm #AMDGPU drivers get their own branch under Instinct #datacenter #GPU moniker
The new #datacenter Instinct driver is a renamed version of the #Linux AMDGPU driver packages that are already distributed and documented with ROCm. Previously, everything related to ROCm (including the amdgpu driver) existed as part of the ROCm software stack.

Does anyone have a collection of .dds (and maybe also .ktx and/or .ktx2) textures I could use to test my texture viewer (https://github.com/DanielGibson/texview)?

For DDS I only found test textures from GLI and unfortunately many of them are invalid/broken :-/
For KTX(2) I have the ones from libktx (and the broken ones from GLI).

Thanks in advance! :)

ЦОДы, GPU, NVIDIA A16, охлаждение: о серьезных вещах простым языком

Добрый день, дорогой читатель. Меня зовут Селезнев Павел, я инженер второй линии поддержки в облачном провайдере Nubes. С каждой новой статьёй я расту в должности, поэтому пишу ещё одну :) Несколько месяцев назад нам с коллегой поставили задачу: провести сравнительные тесты, чтобы проверить, насколько сильно разогреется видеокарта под нагрузкой при использовании воздуха и диэлектрической жидкости. Об этих тестах я и расскажу в статье, которая должна пролить свет на жизнь GPU в ЦОДе. Предисловие Как понятно из названия статьи, речь пойдёт о жизни GPU в контексте ЦОДа (центра обработки данных), проведённых тестах разных вариантов охлаждения и выводах, к которым пришла наша команда по итогу этих самых тестов и рассуждений. Тестировали мы GPU NVIDIA A16 в течение нескольких дней. На момент написания материала в нашем ЦОДе реализована система охлаждения посредством использования прецизионных кондиционеров, а в качестве хладагента — фреон. Данная система представляет собой большие промышленные шкафы (кондиционеры), которые беспрерывно охлаждают нагретый оборудованием воздух с помощью того самого фреона. На картинке упрощённо показан процесс теплообмена.

Shadertoys 移植至 Rust GPU
➤ 使用 Rust 開發 GPU 程式：以 Shadertoy 移植為例
✤ https://rust-gpu.github.io/blog/2025/04/10/shadertoys/
這篇文章介紹了將流行的 Shadertoy 著色器移植到 Rust GPU 的過程。Rust GPU 允許使用 Rust 程式語言編寫 GPU 程式，並將其編譯成 SPIR-V 格式，使其與 Vulkan 兼容。移植過程相對順暢，並展示了 Rust 在 CPU 和 GPU 之間共享程式碼的優勢，以及對 traits、泛型和宏的支持。此外，作者也回饋了 wgpu 和 naga 專案，修復了幾個問題，並鼓勵更多人參與 Rust GPU 的開發。
+ 哇，Rust 竟然也能開發 GPU 程式！這感覺很酷，以後可以嘗試用 Rust 寫一些圖形效果。
+ 聽起來 Rust GPU 解決了 CPU 和 GPU 之間資料共享的痛點，這真的很棒！期待未來能看到更多 Rust GPU 的應用。

"Just going to test the current pkg driver, this will only take a second...", the old refrain goes. Surely, it will not punt away an hour or so of messing about in loader.conf on this EPYC system...

- Here are some notes to back-track a botched/crashing driver kernel panic situation.
- Standard stuff, nothing new over the years here with loader prompt.
- A few directives are specific to this system, though may provide a useful general reference.
- The server has an integrated GPU in addition to nvidia pcie, so a module blacklist for the "amdgpu" driver is necessary (EPYC 4564P).

Step 1: during boot-up, "exit to loader prompt"
Step 2: set/unset the values as needed at the loader prompt

unset nvidia_load
unset nvidia_modeset_load
unset hw.nvidiadrm.modeset
set module_blacklist=amdgpu,nvidia,nvidia_modeset
set machdep.hyperthreading_intr_allowed=0
set verbose_loading=YES
set boot_verbose=YES
set acpi_dsdt_load=YES
set audit_event_load=YES
kern.consmsgbuf_size=1048576
set loader_menu_title=waffenschwester
boot

Step 3: login to standard tty shell
Step 4: edit /boot/loader.conf (and maybe .local)
Step 5: edit /etc/rc.conf (and maybe .local)
Step 6: debug the vast output from kern.consmsgbuf logs

GitHub - Rust-GPU/Rust-CUDA：使用 Rust 撰寫和執行快速 GPU 程式碼的生態系統
➤ 打造 Rust 在 GPU 計算領域的地位
✤ https://github.com/Rust-GPU/Rust-CUDA
Rust-CUDA 是一個專案，旨在使 Rust 成為使用 CUDA 工具包進行高效能 GPU 計算的首選語言。它提供了一系列函式庫和工具，可將 Rust 編譯為快速的 PTX 程式碼，並與現有的 CUDA 函式庫整合。 該專案包含 `rustc_codegen_nvvm` (Rust 編譯器後端)、`cuda_std` (GPU 端功能)、`cudnn` (深度神經網路加速)、`cust` (CPU 端 CUDA 功能)、`gpu_rand` (GPU 隨機數產生) 和 `optix` (光線追蹤) 等多個 crates，旨在覆蓋整個 CUDA 生態系統。 儘管目前仍處於早期開發階段，但 Rust-CUDA 旨在克服以往 Rust 與 CUDA 整合的困難，並充分利用 Rust 的優勢，如效能

My nephew is building a new PC, and one little detail is holding it up: the 6+2 PCIe connector bumps out too much and hits a small lip on the back plate So, the connector can't sit tight and flush nor lock-in

Does anyone know of good quality compatible cables that have a straight 8-pin connector or no long locking seam for the 6+2
One option would be to snip out the little bit that's holding up on that lip
