Because the SIMD approach is bad for 2D on 2D matrix multiplication NVIDIA has introduced:
Tensor Cores in the Volta architecture.
Article about it:

Or when you attended a gathering/event then read about it and think that that was an entirely different event.
“newspaper from ten years ago, … what happened in the topic afterwards and then judge how informative the article was”
As a German you will know the saying: “Nichts ist so alt wie die Zeitung von gestern.” → “Nothing is as old as yesterdays paper.”
N.N. Taleb calls it noise.
At fist it is either wrong or without consequence or propaganda, then it is outdated. A historian will find 99% of all “news” to be little more as an “interesting time piece” at best representative for the thinking and style of the era.
Danke
Or you read: https://en.wikipedia.org/wiki/Propaganda_model
There is a non zero risk of death. There have been cases where some candidates had severe permanent damage and it took a while to figure out why. We are all slightly different.
Even with animal trials there is a risk. I do not think there is an answer to your question.
Oh, I should have mentioned that this is also assuming that there is a constant factor between the total number of infected in the past to the number of currently infectious. Which is true as long as the spread is exponential, but that is the entire assumption anyhow.
In Germany the data is ATM consistent with:
+22% infected per day which is exactly +3 people infected after one week after the infection by every infected. (This is assuming that there no imported cases, 7th root of ((1+3)/1))
“only a minority of people use a bicycle for anything other than recreation”
I guess my upbringing and surrounding is special (densely populated area in north Europe), but I know plenty of people who move in no other way (shopping, vacation, commute, everything). Before the gasoline motor scooter became wide spread, and poisoned the air in Asia, people used bikes all the time.
Please elaborate on why you think the bicycle “merely offer convenience or entertainment”. I understand that people did not understand it’s potential and thought of it as a toy for crazy people, but wasn’t the same true for the gasoline-automobile? To me the bicycle is of great importance, not just/only for leisure, sport. I understand that the bicycle’s value depends on the distance, flatness, wind, road quality traveled, but compared to a horse (that most did not have) it is so much better.
The entire SIMD vector approach is good for many dot products but it is not the same as a systolic array for rank two on rank two multiplication.
If the job would be to multiply two 1024x1024 matrices then a systolic array of 256x256 MACs would be a good choice. It would work four times on 256x1024 by 1024x256 matrices for 1024+256 steps.
To me there is a difference between the hardware for 1xN by Nx1 and MxN by NxM (with N > M > 1). Although any matrix operation is many 1xN by Nx1 dot products, doing them independently would be inefficient.
”If you do a matrix multiplication the obvious way, this results in dot products of rows and columns (one for each element of the resulting matrix). So it seems to me that improving matrix to matrix multiplication performance comes from improving the performance of dot products.”
True, but not individual dot products, but the collective of very many dot products. Obviously you do not do it the obvious way as you would have to load the same data over and over again.
An example of a systolic algorithm might be designed for matrix multiplication. One matrix is fed in a row at a time from the top of the array and is passed down the array, the other matrix is fed in a column at a time from the left hand side of the array and passes from left to right. Dummy values are then passed in until each processor has seen one whole row and one whole column. At this point, the result of the multiplication is stored in the array and can now be output a row or a column at a time, flowing down or across the array.https://en.wikipedia.org/wiki/Systolic_array
[Question] Matrix Multiplication
True, I had not claimed that all criteria could or have been met. Because of the noise and the heat I just the other day replaced the inductive load in some of my very old but still fully functioning kitchen counter lights, with modern switching current regulators. The 50 Hz produce a 100 Hz tone that had been bothering me for decades. But even some of those can be heard by some people. (Not me I am deaf to anything >10kHz)
It is a compromise in an area of sensory overlap but the human senses are not equally sensitive to all frequencies. Your hearing is way better at 3kHz. At your age you will still remember CRT monitors that would operate at 60 Hz at max resolution, bad but they did get used.
Why 50/60Hz? It has to be too low to be heard, to high to be seen, high enough for transformation, low enough for low induction losses, low enough for simple rotating machines. Trains can not use 50⁄60 so they went with 1⁄3 (16+2/3 Hz or 20 Hz)
Grid frequency is controlled to +-150mHz if that fails private customers might get disconnected/dropped.
The time derivative of the grid frequency is a measure of the relative power mismatch.
I observe a radicalization that is driven by what I call the concept of “counter crazy”. It let to Trump but I have been aware of it for longer on the left. The idea is that by being more radical in the way, that you think the world needs to be, you could achieve that. It is compounded by the tribalism and identity culture.
The idea of “you can not speak on this because you are not a woman / …” is recent to me. But has been expressed by the most intelligent female I know. It is a scary idea.
The idea of cushioning life is a generational thing and related to U.S. product liability law. No matter how dumb, misinterpreting, interpreting in bad faith or sensitive you are, others are responsible for your feelings no matter how unjustified. The Snowflake generation can not surprise anyone, we were watching as they were raised to be what they have become.
There is much more awareness of the issue thanks to the members of the “intellectual dark web” and comedians such as Ricky Gervais, Bill Maher, Joe Rogan.
The PC culture is nothing new. It has been impossible to talk about many topics for four decades. And obviously there are “good” reasons. People are unable to talk about these issues without confusing separate issues, values, preferences. To me it is painful to listen to the arguments because they are so confused and old. Most (including scholars and journalists) are simply unable and should indeed not talk on these issues because it does lead nowhere. What we have now is a result of not having talked about important topics for decades, massive preference falsification/concealment and having generations growing up in that environment.
I found this recent Dilbert cartoon to be a good summery of the issue with being smart in a complex random world:
The way you commented it is not clear what you are referring to. I did not understand your comment because I did not get “where you were coming from”.
Straw_Vulcan is an example of an attack of two of the three types of thinkers on another.
The moral-thinkers try to show their superiority. In Star Trek this is ever present. In all the stories morality and principles always win over rational compromise. The captains usually favor the best possible short term outcome over risk minimization and the long term. As it is fiction this always works out.
The three thinking types as formalized/categorized (to my knowledge) by Rao Venkatesh of ribbonfarm.

I can hardly express how useful I found this to make sense of the world.
Put that way I completely agree.
Why did you not go for engineering (like me)? Still some math proves but no one listens and they will not test it either.
Twice I made the mistake to ask ‘why’ it is the way it is. All I got was “look at the prove, it works out”. That is why have have little respect for mathematicians i.g..
