I also maintain the build system for Halide, but as it's less greenfield, there are some things I would need team buy-in to change. It's also much more complex (building code generators necessarily is). I'm still pretty happy with it, though. See here: https://github.com/halide/Halide

Project mention: [D] Neural Networks using a generic GPU framework | reddit.com/r/MachineLearning | 2022-01-04
Looking for frameworks with Julia + OpenCL I found array fire. It seems quite good, bonus points for rust bindings. I will keep looking for more, Julia completely fell off my radar.

Scout APM
Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

> [...] how Perf compares to vendor tools like vTune [...] ?
Regarding the hardware events that Perf can capture on x86, it has pretty much all of them. So it should be equivalent to vTune for all practical purposes.
The big difference is in the UI -- or absence thereof. Perf is a low-level tool and its output is mostly text files. There is a curses-based TUI for perf-report (and even gtk version, but it is essentially the same as the TUI, just using GTK2 widgets), but that's about it.
By contrast, vTune comes with a heavy (electron-based?) GUI and is quite helpful in guiding beginners, with many graphs and explanations.
Of course, one can (and is expected to) complement Perf with an assortment of tools that process its output for visualization. For example, the flamegraph [1] and heat map [2] tools described in the article. But also KDAB hotspot [3] or HPerf for a vTune-style perf-report.

If using the command line, just open gitk. If using GitHub, look under the network tab.

ultimatepp
U++ is a C++ cross-platform rapid application development framework focused on programmer's productivity. It includes a set of libraries (GUI, SQL, Network etc.), and integrated development environment (TheIDE).
Project mention: New 3.1.6 release of wxWidgets, free and open source library for creating portable native GUI applications, adding transparent support for high DPI artwork and much more, is now available. | reddit.com/r/cpp | 2022-04-05Have you tried Ultimate++? It's cross-platform, but unlike Qt, it uses native widgets on Windows.

timemory
Modular C++ Toolkit for Performance Analysis and Logging. Profiling API and Tools for C, C++, CUDA, Fortran, and Python. The C++ template API is essentially a framework to creating tools: it is designed to provide a unifying interface for recording various performance measurements alongside data logging and interfaces to other tools.
timemory is my recommendation as the backend if you want to build something custom

flamethrower
a DNS performance and functional testing utility supporting UDP, TCP, DoT and DoH (by @ns1labs) (by DNS-OARC)

Somewhat selfishly, one of the tools I see missing from your guide is the OpenCL Intercept Layer. This is an open-source tool we've developed and we use it every day to debug and analyze OpenCL programs.
