vroom VS hn-search

Maybe implement a big feature for a open source design? like vroom or xiangshan.

The two most micro architecturally advanced cores that I know of are BOOM, an out of order RV64GC core with all the features you expect plus sort of weird fancy things like short forward branch predication, and VROOM, another out of order RV64GC core with things like uop fusion and a trace cache.

I had VROOM! in mind (https://github.com/MoonbaseOtago/vroom) because I remembered it aims for 4 IPC avg with a width of 8. Though looking again it's 8 compressed 16 bit instructions or 4 uncompressed 32 bit instruction.

So you could argue a real mix of instructions is not going to be all 16 bit but some 16 and some 32, so the 8 is rarely achieved in practice, and also the block diagram only shows 4 decode blocks. But it can in fact peak at 8 instructions decoded per clock, so I think that qualifies. (You could even argue it's especially impressive, since RISC-V technically qualifies as variable-length encoding like x86, it's just that only 16/32 instructions are really used at the moment)

If you are interested in high performance look into vroom , c910 and xianghan, maybe you could adopt one of them.

On top of what others mentioned (Red Hat) , it is also possible to go with the mysql/mariadb model of dual licensing, you can have a copyleft license where you must contribute back changes, but also allow selling an proprietary license if they want to enhance it but not share the improvements (like amazon or Ampere Computing that enhance ARM designs and sells it for servers), there is already a RISK-V implementation that aims to do that (vroom). another option is a non profit foundation that companies contribute to because they use the project and want it to be better (like the linux foundation) , risc-v has similar nonprofits like the chips alliance (which develops the Rocket-Chip ) or the OpenHW Group (which develops CVA6), there is also lowrisc which develops ibex (but as far as i can tell isn't governed by the contributing companies like the other non profits).

You want a very optimistic answer? someone is working on open source server core, It is already announced and i have been told it is somewhere around four years for a chip to ship after announcement so i would say 4 years from now.

At the moment the Apple M1/M2 are the king of wide decode. Within a couple of years you will see equally wide decode and execute of RISC-V from companies such as Rivos, or indeed open source and GPL'd projects such as VROOM! (https://github.com/MoonbaseOtago/vroom)

> True performance RISCV designs are going to be people's money maker and never open sourced.

That turns out not to be the case.

Alibaba's C910 core -- roughly comparable to the ARM A72 cores (at the same MHz) in the Pi 4 -- is open sourced. It is being used, at 2.5 GHz, in the upcoming "Roma" laptop. That is rather expensive (for now), but I suspect the same TH1520 SoC will quickly find its way onto cheaper SBCs.

There is a very wide OoO GPL'd RISC-V core that is under development. It is aiming for eventual Apple M1 level performance. The current iteration is falling short of that at the moment, but it's already comparable to the ARM A76 in the latest RK3588 SBCs: https://github.com/MoonbaseOtago/vroom

Then you can help open source hardware designs like xiangshan or vroom.

Truly good websites have around 2 facts per 10 word sentence, and get instantly to the chase. Also: good websites give you the names of all their competitors/alternative websites before showing their own stuff, and give you further reading.

Right now the world of technology is supposedly more innovative than ever, but somehow Wikipedia (https://www.wikipedia.org/) and Search Hackernews (https://hn.algolia.com/) beat billion dollar search engines.

Articles written decades ago are still unsurpassed in terms of quality and ease of understanding, but the best modern websites can do is textbook explanations. It is time society graduates from boilerplate buzzword textbook culture.

Now the gems of the internet are slowly being buried beneath mountains of trash.

If something sounds boilerplate it isn't good enough.

Don't bother saying something that has been said before, and better.

Oh, I see. We actually discussed Pound about four years ago - just a little back and forth about the ABC of Reading: https://news.ycombinator.com/item?id=24196681

>What's your explanation of why Pound went Fascist?

I'm not sure I particularly have one; I haven't read any of his longer political or cultural (i.e. non-literary) works. I just think it's silly to correlate an approach to translation that you dislike with fascism. Especially as I'm not sure it even makes sense on its own terms: I can only read your comment as 'lazy translator? Figures that he would be a fascist', but if I imagine the type of translation a fascist would approve of, the approach I picture is fastidious, fussy, concerned with fidelity to the point of stickler-ishness. (Isn't that from where we get 'grammar nazi'?)

And oh, well, since you ask I'll take a shy at it: my vague sense is that he became fascist because saw a society in decline due to it becoming more and more a sham society: opulence without virtue, power without vigour, money no longer tied to actually existing goods. (Of course, all of this shades easily into antisemitism.) He saw fascism as the answer; It's easier to see in retrospect that it wasn't.

"multiplayer notepad" goes back 15 years at least - https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu... notepad&sort=byDate&type=comment

it was used back with a popular website which opened a text document and anyone viewing could type, but I can't remember the name. That became a thing in Google Docs, Microsoft Office, Floobits, and lots of self-hosted and cloned sites.

If you see a post that ought to have been moderated but hasn't been, the likeliest explanation is that we didn't see it. You can help by flagging it or emailing us at [email protected].

Ok, but please don't post unsubstantive comments to Hacker News.

I understand the reason for repeating these sentiments—it's the same reason why they get upvoted to the top of threads*—but repetition of this kind is what we're most trying to avoid here.

* I've marked this one off topic now.

I was looking for it in the guidelines. There are a couple of conventions for postings. Consider a bit of prior examples: [https://hn.algolia.com/?q=show+hn]

yeah there are only three stories coming up from the site search

https://hn.algolia.com/?q=postgres+clustering

only one is semanthically correct, the other pick up the wrong version of clustering (i.e. k-means instead of multi master writes)

but yeah if one doesn't test the hard cases, how does one know it preserves semantics :D

Like dismissing the work of Feyerabend or Wittgenstein without seemingly having read either:
