Anyone aware of any study showing power breakdown of a recent GPU: chip + HBM + NVLink for a recent nvidia gpu (eg H100, B200)?

I just realized that Tony Hoare passed away on March 5th. Hoare, the 1980 Turing Award Winner, will be recalled for many fundamental contributions in CS, among others quicksort, communicating sequential processes and the dining philosophers problem.
Intrigued by FelixCLC's talk at FOSDEM 2026 about RISC-V design decisions. Agree about RVC (compressed) instructions. Seems to add just complication without much use case. Is there a chance that future specs deprecate it? #riscv
Anyone experiencing wifi-only problems using linux+wireguard VPN? eduVPN suddenly stopped working for me two days ago, but only when on wifi. Still works correctly while on ethernet! But other wireguard VPN (eg integrity) work, even on wifi. Suggestions? #linux #wireguard #eduvpn
How many people can say their childhood interests followed them into adulthood? Now imagine rediscovering that interest later in life and using it to change your local community. For #BHM’2026, ACM shares the accomplishments of Marlene Mhangami and her impact on computing.
So, modern GPUs increasingly rely on FP emulation like Ozaki scheme to provide high FP64 flops using using low precision tensor cores. But that will benefit only GEMM codes? Rubin will only have 33 TFLOPS of native FP64, while 200TF of emulated FP64. #HPC

Very nice article from Anthropic on using agent teams to develop a C compiler. x.com/i/status/20...
The OpenMP ARB announces that Python will be supported in 7.0! www.openmp.org/press-relea... I wonder if this means full support a la Fortran/C/C++ or if it will focus on a subset, or just bindings for loading/running OpenMP programs from Python. Excited to see this development!
New Python Subcommittee, and Anaconda joins OpenMP ARB - OpenMP
Python will be the fourth officially-supported language in the OpenMP API, and leading Python infrastructure company Anaconda joins the OpenMP ARB

Nice talk by Sylvester Ledru on Rust Coreutils in Ubuntu! x.com/i/status/20... An interesting opener. Students don't want to learn C, they want to learn Rust. But I believe languages don't exist because they are technically better, they live to serve their communities.

Hari giving a great tutorial on Singularity containers as part of our parallel computing project course DAT630! #HPC
Excited after the first week of our project course on parallel computing. Over the next 7 weeks, 92 students, assembled into teams of 6-7, will tackle an LLM inference optimization challenge (CPU+GPU), and containerize+run key HPC benchmarks (HPL, HPCG, HPL-MP, Graph500) on our local cluster Vera.
Every now and then some students approach me to do projects in Rust, which are lots of fun. But my core teaching language remains C++, and despite FUD coming from a few loud voices, C++ is and likely will remain the major language for performance oriented programming herbsutter.com/2025/12/30/s...
Software taketh away faster than hardware giveth: Why C++ programmers keep growing fast despite competition, safety, and AI
2025 was another great year for C++. It shows in the numbers Before we dive into the data below, let’s put the most important question up front: Why have C++ and Rust been the fastest-growing major…

Sad to learn about the passing of Mike Flynn. Mike made several core contributions to computer architecture, and will long be remembered for the Flynn taxonomy, which my students also study. This ACM sigarch blog summarizes his life and achievements www.sigarch.org/in-memoriam-... #hpc #comparch
