To meet the ambitious environmental goals being proposed at all levels of government, residential air-to-water heat pumps are emerging as a transformative solution to lower carbon emissions, enhance energy efficiency, and reduce utility bills.

In this episode Martin talks with Chris Grindstaff about the fundamentals of performance engineering. The episode discusses when and how to work on performance of client- and server-side systems, what you should take into account during development to avoid performance issues, typical situations that cause performance problems, and some common pitfalls when analysing performance.

Senior performance architect and author of *Systems Performance* Brendan Gregg talks with Robert Blumen about systems performance: how the hardware and OS layers affect application behavior. The discussion covers the scope of systems performance, systems performance in the software life cycle, the role of performance analysis in architecture, methodologies for solving performance problems, dynamic tracing and tracing tools such as DTrace, the disk and file subsystems, the CPU and memory subsystems, and the challenges virtualization poses for performance analysts.

Kirk Pepperdine talks with Diomidis Spinellis about performance optimization. Topics include development practices, tools, as well as the role of software architecture, programming languages, algorithms, and hardware advances.

Casey Muratori caused some strong reactions with a blog post and an associated video in which he went through an example from the “Clean Code” book by Robert Martin to demonstrate the negative impact that clean code practices can have on performance. In this episode, he joins SE Radio’s Giovanni Asproni to talk about the potential trade-offs between performance and the qualities that make for maintainable code, these qualities being the main focus of Clean Code.

Anton Shilov reports via Tom's Hardware: FFmpeg is an open-source video decoding project developed by volunteers who contribute to its codebase, fix bugs, and add new features. The project is led by a small group of core developers and maintainers who oversee its direction and ensure that contributions meet certain standards. They coordinate the project's development and release cycles, merging contributions from other developers. This group of developers tried to implement a handwritten AVX512 assembly code path, something that has rarely been done before, at least not in the video industry. The developers have created an optimized code path using the AVX-512 instruction set to accelerate specific functions within the FFmpeg multimedia processing library. By leveraging AVX-512, they were able to achieve significant performance improvements -- from three to 94 times faster -- compared to standard implementations. AVX-512 enables processing large chunks of data in parallel using 512-bit registers, which can handle up to 16 single-precision FLOPS or 8 double-precision FLOPS in one operation. This optimization is ideal for compute-heavy tasks in general, but in the case of video and image processing in particular. The benchmarking results show that the new handwritten AVX-512 code path performs considerably faster than other implementations, including baseline C code and lower SIMD instruction sets like AVX2 and SSSE3. In some cases, the revamped AVX-512 codepath achieves a speedup of nearly 94 times over the baseline, highlighting the efficiency of hand-optimized assembly code for AVX-512.
