Analyzing Modern Nvidia GPU Cores

arxiv.org/abs/2503.20481

arXiv.orgAnalyzing Modern NVIDIA GPU coresGPUs are the most popular platform for accelerating HPC workloads, such as artificial intelligence and science simulations. However, most microarchitectural research in academia relies on GPU core pipeline designs based on architectures that are more than 15 years old. This paper reverse engineers modern NVIDIA GPU cores, unveiling many key aspects of its design and explaining how GPUs leverage hardware-compiler techniques where the compiler guides hardware during execution. In particular, it reveals how the issue logic works including the policy of the issue scheduler, the structure of the register file and its associated cache, and multiple features of the memory pipeline. Moreover, it analyses how a simple instruction prefetcher based on a stream buffer fits well with modern NVIDIA GPUs and is likely to be used. Furthermore, we investigate the impact of the register file cache and the number of register file read ports on both simulation accuracy and performance. By modeling all these new discovered microarchitectural details, we achieve 18.24% lower mean absolute percentage error (MAPE) in execution cycles than previous state-of-the-art simulators, resulting in an average of 13.98% MAPE with respect to real hardware (NVIDIA RTX A6000). Also, we demonstrate that this new model stands for other NVIDIA architectures, such as Turing. Finally, we show that the software-based dependence management mechanism included in modern NVIDIA GPUs outperforms a hardware mechanism based on scoreboards in terms of performance and area.

Will the media learn the right lesson from the Ronna McDaniel debacle?

Sadly, #MSNBC #management couched the decision to drop #Ronna #McDaniel in a blizzard of corporate speak.

(“No organization, particularly a newsroom, can succeed unless it is cohesive and aligned … It has become clear that this appointment undermines that goal.”)

Funny — the journalists who spoke up said McDaniel’s departure was required to
🔸preserve their journalistic mission and the network’s credibility,
🔸not out of any need for “alignment.”

We can only hope that NBC and other news organizations take away something more than “don’t hire a MAGA mouthpiece”

A few ideas:

• Create a #mission #statement that affirms your goals are telling the #truth and defending #democracy, which protects the First Amendment — not fake balance.
• #Stop #pretending four-times-indicted former president Donald Trump and his movement are presenting #alternative#policies” as a normal party would. They are fighting for an alternate system: authoritarianism.
• Politicians’ outright #lies must be identified, not just labeled as their “response” or “position.”
• Instead of obsessing over #polls, devote extensive coverage to #analyzing the Heritage Foundation’s “#Project2025” and Trump’s #fascist #agenda. Feature #historians and political #scientists during news segments (not only on panels) to put Trump’s views and statements in context.
• #Don’t excerpt a few words from a Trump rally or speech, dub it an “argument” and #ignore his mental short-circuits and #deteriorating #intellect.
