konradha··on Quasar 438B: Europe's Leading AI Model
It is beyond me how they managed to acquire such funding. Sounds a lot like an earlier quantum computing effort which pivoted to "AI" as well: https://zapataquantum.com
konradha··on GPU Offload in Rust: Portable, Safe, and Fast
What's the easy way here? Linking CUDA into your Rust binary?
konradha··on Porting nanochat to a TPU: what carries over from PyTorch, and what breaks
Every engineer who's worked with "agentic" workflows can tell that this is entirely generated with very little tweaks. It's embarrassing.
konradha··on Ask HN: How did you land your first projects as a solo engineer/consultant?
This is a strong assertion that's directionally wrong. No matter the economy's state or any AI progress, experts are always searched for.
konradha··on CERN uses ultra-compact AI models on FPGAs for real-time LHC data filtering
How are FPGAs "bruned into silicon"? Would be news to me that there are ASICs being taped out at CERN
konradha··on Kidnapped by Deutsche Bahn
The millstones of the gods grind late, but they grind well. It depends where you're from -- there is always potential for dramatic change in a people as obedient as the German.
konradha··on Kidnapped by Deutsche Bahn
I do hope that sufficient humiliation will suffice for DB leadership to enact harsh measures. German precision and punctuality are still there in its people. It's not lost yet.
konradha··on CUDA-l2: Surpassing cuBLAS performance for matrix multiplication through RL
I've been trying my hand at RL envs for various sparse matrix algorithms in CUDA. It's easy to generate code that "looks good", "novel" and "fast". Escaping the distribution and actually creating novel sequences of instructions or even patterns (has any model come with something as useful as fan-in/fan-out or double buffering patterns that's now ubiquituous?) seems difficult to say the least.
konradha··on Canoeing on the Danube
80kms for the longest day, amazing. The most I achieved in the north of Berlin was about 30kms/day. Also, is "Shengan" a british spelling quirk?
konradha··on DeepSeek's AI breakthrough bypasses industry-standard CUDA, uses PTX
Next article: What's SASS?
konradha··on Ask HN: Who is hiring? (November 2024)
I'd be interested as well!
konradha··on No installation required: how WebAssembly is changing scientific computing
There is project bringing Fortran to the browser, though (_using WebAssembly_)

https://dev.lfortran.org/

konradha··on Ask HN: How can I learn about performance optimization?
Read some of the performance-related work here: https://acl.inf.ethz.ch/publications/
konradha··on Germans piece together millions of lives spied on by Stasi (2011)
I know some people who took a look at their StaSi files. Today's really different compared to what happened then: There wasn't someone from inside your inner circle transmitting every joke and every utterance to "law enforcement" for them to build kompromat. Sure, nowadays your every move is sold to god-knows-who but this will not impact your ability to choose a course of study (which may or may not suit you academically). You can get a job anywhere provided you have clearance and education needed. You will not look at pictures from your childhood and realize that three out of five people sold you out to get ahead in the queue to acquire a car. Your most intimate thoughts and acts aren't recorded for random bureaucrats to get a laugh out of. Please think again before equivocating "den Realen" with modern democracy. Neoliberal, consumerism societies definitely have their flaws but you're definitely better off on the freedom scale.
konradha··on JAX – NumPy on the CPU, GPU, and TPU
Would you happen to have sources on the three orders of magnitude speedup coming at no cost? I'd assume porting + data movement considerations making this task non-trivial.
konradha··on Lfortran: Modern interactive LLVM-based Fortran compiler
LFortran is not necessarily using LLVM IR to compile. It's building up an ASR [1] structure that's already being used in the LFortran-specific backends. Potentially it can make full use of Fortran semantics!

konradha··on Ask HN: What are the best papers you read in your life?
Oh absolutely. That work is a gem, I've used it for quite some research. Good idea to refer to this, too!
konradha··on Ask HN: What are the best papers you read in your life?
How to write Fast Numerical Code

https://users.ece.cmu.edu/~franzf/papers/gttse07.pdf

konradha··on Quantinuum H-Series quantum computer
Disentangling hype from practicality: https://arxiv.org/abs/2307.00523
konradha··on Germany’s top financial supervisor dismissed a decade of warnings about Wirecard
How so?
konradha··on A ‘regime shift’ is happening in the Arctic Ocean, Stanford scientists say
'Regime shift' is a fairly common term when talking in the context of time series.
konradha··on Hague court orders Dutch state to pay out over colonial massacres
https://en.wikipedia.org/wiki/Herero_and_Namaqua_genocide
konradha··on Switzerland Federal Council bans large-scale events
Of course it's cancelled, Berset put 1000 people as a hard maximum with events with below 1000 people attending only allowed under risk assessment measures (ie. they might even cancel events below that threshold).
konradha··on Introduction to High-Performance Scientific Computing (2014)
Since it does not treat technologies but rather concepts, it is very much up to date. Everybody in HPC does Monte Carlo and parallel processing, these concepts are still fundamental to working in scientific computing.
