Surfer deserves to hit the front page also. Much better than gtk wave. Nice work Spade & Surfer!

I'm curious about the results under the section titled "Demonstration." The author claims that ground truth is that each goroutine utilizes 10% of the CPU time (so stipulated that this should be the case). But, what if the

I have a theory that news occurs with a far lower frequency than people think, far lower than even when people try to account for their knowledge of the 24 hr. news cycle. In my theory, most of what counts for news, is either a story update

Thank you for the insight! Just for clarity, I'm using "autopilot" as a catch-all term that refers the automated systems that plausibly seem to have caused these crashes.

It's not nice that so many writers parrot that the solution is "more pilot training." Under the hypothesis that there needs to be a solution (one that I think is correct), then the answer of more training amounts to mere hope

For chips, power scales with voltage squared. Is also true that P=IV (since both are true, these observations cannot be in contradiction). Apparently, for chips, the current must be proportional to voltage also. Glossing over some details,

I think it is linear for frequency and non-linear for voltage, i.e. P~f C V^2. But in many current CPUS, the feature that adjusts frequency also adjusts voltage. That's why I stipulated that, for my comments to be true, such shenanigan

It should be the case that if the same amount of work is done, then the energy used will be the same. If it takes less work to compile the web assembly, then less energy (holding all other parameters the same). If you have to idle a CPU, th

If Bezos gave all his money to everyone in the world we would all get maybe $13 or so. If all the billionaires did the same we would all get $1000 or so.

Hi stjepang, If the following criteria is met, then perhaps the branch mis-predict penalty is less of a problem: 1. you are sorting a large amount of data, much bigger than the CPU LLC 2. you can effectively utilize all cores, i.e. your sor

I think maybe we were talking past each other. Yes there is more than one reason. It's far easier to add capacity by adding sets, as opposed to ways. But they can't add sets in the L1 because of the aliasing problem. When they do

Hi, it is the main reason L1 hasn't grown. By your reasoning, no cache should be able to grow, because then their latency would increase too much. But instead, all other CPU caches are growing basically with iso-latency. The reason thi

by etep 9y ago
At a high level it's true that smaller is faster, but it's also true that those L1s could have grown by adding sets (not ways) and achieved the same latency. L2 has grown, but stayed iso-latency. This seems to say that "small

If it was easy to build high performance caches with high associativity, we would certainly see higher associativity. Ideally, you want a fully associative cache, but it's too expensive. In CPU caches, once a set is selected, all N ass

by etep 9y ago
I had wondered, why are the L1 caches not growing, while L2 and L3 capacities continue to grow: a significant limitation on L1 cache size is actually the fixed tradeoff between associativity, page size (i.e. the 4KB pages allocated by the O

My point exactly, not the most lucrative. So what remains is the implicit assertion they are fleecing the big time guys. And somehow the big time guys remain in business... so what's going on?

People like to say the market is a zero sum game, but I have always been suspicious of this truism. Its fair to say that participants can leave the market, but in practice that isn't what we see. In practice there are firms doing this

If the market is a zero sum game, then for every winning trade, there must be a losing trade. Obviously some teams must be winning consistently, which implies that some are losing consistently. This says that the consistent losers go out of

I really like the "parallel" by default paradigm, or perhaps rather, I think it has great potential. When you consider any hardware design (Verilog, Chisel, etc.) the default is to execute in parallel, and sequential is explicit i

I agree with this; nothing I wrote is intended to contradict that or dispute it, didn't mean to convey it as such. Thanks for the link, it was very interesting.

No one could so thoroughly eviscerate my favorite novel except Malcolm Gladwell. I take his point. His criticism imagines a better hero, one who would righteously proclaim truth. But this is also unfair. Had A.F. done this, he would have lo

I find this article to be self-contradictory. The premise is that you should diversify outside of your geographic economic ecosystem, but the claims continue that the whole economy is connected (i.e. when there is a rush for the exit). Agre
