Intel's Linux Performance Optimizations Continue Paying Off for AMD EPYC (phoronix.com)
As part of my end-of-year benchmarking and various historical comparisons, over the holidays I was curious to take a look at how the mature AMD EPYC 9004 "Genoa" performance has evolved over the past two years under Linux.

I helped fix sleep-wake hangs on Linux with AMD GPUs (gitlab.io)
I dual-boot my desktop between Windows and Linux. Over the past few years, Linux would often crash when I tried to sleep my computer with high RAM usage. Upon waking it would show a black screen with moving cursor, or enter a "vegetative" state with no image on-screen, only responding to magic SysRq or a hard reset. I traced this behavior to an amdgpu driver power/memory management bug, which took over a year to brainstorm and implement solutions for.

How AMD Is Taking Standard C/C++ Code to Run Directly on GPUs (phoronix.com)
Back at the 2024 LLVM Developers' Meeting was an interesting presentation by AMD engineer Joseph Huber for how they have been exploring running common, standard C/C++ code directly on GPUs without having to be adapted for any GPU language / programming dialects or other adaptations.

AMD Disables Zen 4's Loop Buffer (chipsandcheese.com)
A loop buffer sits at a CPU's frontend, where it holds a small number of previously fetched instructions. Small loops can be contained within the loop buffer, after which they can be executed with some frontend stages shut off. That saves power, and can improve performance by bypassing any limitations present in prior frontend stages. It's an old but popular technique that has seen use by Intel, Arm, and AMD cores.

Pushing AMD's Infinity Fabric to Its Limits (chipsandcheese.com)
I recently wrote code to test memory latency under load, seeking to reproduce data in various presentations with bandwidth on the X axis and latency on the Y axis. Ampere pretty much described how that was done during their Hot Chips 2024 presentation. To achieve the same results in a semi-automated fashion, I run a latency test thread while also running a variable number of threads that generate bandwidth load.

AMD now has more compute on the top 500 than Nvidia (nextplatform.com)
There has been a lot more churn on the November Top500 supercomputer rankings that is the talk of the SC24 conference in Atlanta this week than there was in the list that came out in June at the ISC24 conference in Hamburg, Germany back in May, and there are some interesting developments in the new machinery that is being installed.
