In cpu uarch design, sure, but that's outside the context of the discussion. There's nothing you can do to that C++ library you are optimizing that will impact performance due to register allocation/renaming.

Your critique applies to measuring one or a handful of instructions. In practice you count the number of cycles over million or billion instructions. CPI is very meaningful and it is the main throughput performance metric for CPU core arch

Register moves do not really play a factor in performance, unless its to move to/from vector registers.

Yes and just like our bodies, that closed loop is cooled by a rack of evaporators on the roof.

It doesn't need to prove that. It needs to produce plausible data that appeases either your direct or +1 manager.

This is a pointless pissing match. It took decades to develop EUV into a high volume tool with R&D effort from different regions that each now contribute to some key part of the tool and supply chain. ASML or Zeiss does not make it a EU

Go is a bit more of a low level language compared to actor languages where the language enforces that programming model. I think the point of the slogan is that you want to make the shared memory access an implementation detail of your larg

On the software side I can recommend https://github.com/DrTimothyAldenDavis/GraphBLAS It is hard to make a sparse linear algebra framework, but Tim Davis has been doing a great job collecting the various optimal algori

A note on the hardware part: it does not require NN-specific hardware akin to neuromorphic. Sparse compute oriented architectures already have been developer for other reasons, such as large scale graph analysis or inference. It will still

> Unstructured sparsity cannot be implemented in hardware efficiently if you still want to do matrix multiplication. Hard disagree. It certainly is a magnitude harder to design hardware for sp x sp MM, yes; it requires a paradigm shift t

Sparse matrices can increase in dimension while keeping the same number of non-zeroes, that part is self evident. Sparse weights models can be trained, you probably are already aware of RigL and SRigL, there is similar other related work on

by yvdriess 11mo ago
What do you mean by work better here? If it's for better accuracy then no they are not better at the same weight dimensions. The big thing is that sparse models allow you to train models with significantly larger dimensionality, blowin

There has been plenty of evidence over the year. I don't have my bibliography handy right now, but you can find them looking for sparse training or lottery ticket hypothesis papers. The intuition is that ANNs make better predictions on

Yes! I'de been advocating for it inside the industry for a decade, but it is an uphill battle. The researchers can't easily publish that kind of work (even Google researchers) because you don't have the hardware that can real

I will absolutely try this one out, it looks a lot more useful than binding caps lock.

It pops up a surprising number of times. Keysets or chorded keyboards have been around since The Mother of all Demos, but never really seemed to have caught on. It makes sense to me to put them at your feet to chord some common actions or m

It is fairly common for emacs users to bind Ctrl or Meta to caps lock for improved ergonomics. There's also a bunch of RSI sufferers that are using foot pedals, which actually makes a lot of sense. I personally switched to emacs for mo

Agree, those hangs are especially bad when programming with eglot or project management over a slow Tramp (remote) connection. An auto save hijacking your time for two seconds at random is flow breakingly frustrating. It's something th

Yep, it's awesome how Michael keeps crediting collaborators, given how much of the work is his. Good job!

Well yes, the dialects are very distinct linguistically, but what is often referred to as Flemish is the Dutch "tussentaal" aka "verkavelingsvlaams"[1]. That's not really a language per se, it's a regiolect of

by yvdriess 1y ago
Flemish is more of a political construct than linguistic, it's a grouping of belgian-dutch the coastal, brabant and limburg language groups with each having their own regional dialects.

If ARM's memory tagging is a guide, not much for the general developer. You will be able to run with address sanitizers enabled at a much lower overhead. Perhaps, use some hardened allocators or library variants that rely on the extens
