            Dramatic drop in numpy fromfile performance when switching from python 2 to python 3
            Asked 2022-Mar-16 at 23:53
            Background

            I am analyzing large (between 0.5 and 20 GB) binary files, which contain information about particle collisions from a simulation. The number of collisions, number of incoming and outgoing particles can vary, so the files consist of variable length records. For analysis I use python and numpy. After switching from python 2 to python 3 I have noticed a dramatic decrease in performance of my scripts and traced it down to numpy.fromfile function.

            Simplified code to reproduce the problem

            This code, iotest.py

            1. Generates a file of a similar structure to what I have in my studies
            2. Reads it using numpy.fromfile
            3. Reads it using numpy.frombuffer
            4. Compares timing of both
            ...

            ANSWER

            Answered 2022-Mar-16 at 23:52

            TL;DR: np.fromfile and np.frombuffer are not optimized to read many small buffers. You can load the whole file in a big buffer and then decode it very efficiently using Numba.

            Analysis

            The main issue is that the benchmark measure overheads. Indeed, it perform a lot of system/C calls that are very inefficient. For example, on the 24 MiB file, the while loops calls 601_214 times np.fromfile and np.frombuffer. The timing on my machine are 10.5s for read_binary_npfromfile and 1.2s for read_binary_npfrombuffer. This means respectively 17.4 us and 2.0 us per call for the two function. Such timing per call are relatively reasonable considering Numpy is not designed to efficiently operate on very small arrays (it needs to perform many checks, call some functions, wrap/unwrap CPython types, allocate some objects, etc.). The overhead of these functions can change from one version to another and unless it becomes huge, this is not a bug. The addition of new features to Numpy and CPython often impact overheads and this appear to be the case here (eg. buffering interface). The point is that it is not really a problem because there is a way to use a different approach that is much much faster (as it does not pay huge overheads).

            Faster Numpy code

            The main solution to write a fast implementation is to read the whole file once in a big byte buffer and then decode it using np.view. That being said, this is a bit tricky because of data alignment and the fact that nearly all Numpy function needs to be prohibited in the while loop due to their overhead. Here is an example:

            Temporality of ST64B and MOVDIR64B
            Asked 2022-Feb-17 at 01:47

            x86_64 has an instruction movdir64b, which to my understanding is a non-temporal copy (well, at least the store is) of 64 bytes (a cache line). AArch64 seems to have a similar instruction st64b, which does an atomic store of the same size. However, the official ARMv9 documentation is not clear about whether st64b, too, is a non-temporal store.

            Intel's instruction-set reference documentation for movdir64b is much more detailed, but I'm not far along enough in my studies to fully understand what each memory type protocol represents.

            From what I could deduce so far, the x86_64 instruction movntdq is roughly equivalent to stnp, and is write-combining. From that, it seems as if movdir64b is like four of those in one atomic store, hence my guess about st64b.

            This is almost certainly an oversimplification of what's really going on (and could be wrong/inaccurate, of course), but it's what could deduce so far.

            Could st64b be used as if it were an atomic sequence of four stnp instructions as a non-temporal write of a cache line in this way?

            ...

            ANSWER

            Answered 2022-Feb-17 at 01:47

            The ST64B/ST64BV/ST64BV0 instructions are intended to efficiently add work items to a work queue of an I/O device that supports this interface. When the target address is mapped to an I/O device, the store is translated as a non-posted write transaction, which means that there has to be a completion message that includes a status code as described in the documentation. The ST64B instruction simply discards the status code while the other two store it in the register specified by the Xs operand.

            If you look at the pseudocode, these instructions require the target address to be in uncacheable memory:

            The loop for element in data: iterates over the entire dataset for every row. You need to adjust it to run in chunks of size len(days), incrementing for each row.

            There are a couple of ways of doing that. A complicated way would be to make an iterator that chunks up data and zip it with classes.keys in the outer loop. A much simpler approach would be to maintain a counter between runs of the outer loop:

            Highlighting problem in Jupyter Notebook - VSCode
            Asked 2022-Feb-02 at 02:25

            Lately when using Jupyter Notebook in VS Code to write some assignments for my studies I ran into a quite annoying problem - whenever there is a mistake in my code cell that prevents it from running, the "traceback" (or however you call it) to the place where the error persists is colored with a high-contrast marker (the color depends on the theme used) and makes the content pretty much invisible unless you manually "select" it with the mouse coursor. Is there any way I could fix it without going too much in-depth into VSCode/Jupyter Notebook extension settings?

            The highlighting looks like shown below.

            Angular v12 Component style files not compiling tailwindcss @apply
            Asked 2022-Jan-26 at 11:32

            I am a student in computer science and I am working on a project for my studies. I currently try to develop a component library for the Angular framework using Angular V12. For styling I want to use Tailwindcss (especially because it spares me with working with media queries on some points...). Anyway, when I build the library and test it in another project, no tailwind styles are included.

            I know from the tailwind docs, that you can use some directives or functions like @apply in plain scss.

            To give you a better understanding on the problem I have linked the github repo to the library's source code for reference. I have a button component which should have some tailwind styles applied. This is done by specifying a class to the html element called .btn. This class is defined inside the button.component.scss file. This file is as well referenced in the button.component.ts file as styleUrl. So my question is: How can I fix the issue with the styles not being applied using @apply inside button.component.scss?

            This is how the styles are defined in button.component.scss:

            How to improve the HTML Table Styling that is to be converted into a PDF File
            Asked 2022-Jan-25 at 00:43

            This image has 13 columns, I don't want that. I want to keep 5 columns but my major concern is the size of the td in my HTML files. It is too small in width and that is why, the text is also very stacked up in each td. But if you look at the other image, text is much more visible and boxes are much more bigger width wise. Moreover, it doesn't suffer from height problems either (the height of the box is in such a way that it covers the whole of the PDF Page and all the tds don't look like stretched down)

            I have tried to play around the height and width of my td in the HTML File, but unfortunately, nothing really seemed to work for me.

            What I've done here is remove the borders from the table and collapsed the space for them.

            I've then used more semantic elements for both table headings and your actual content with semantic class names. This included adding a new element for the elements you want at the bottom of the cell. Finally, the teacher and codes are floated left and right respectively.

            I am not much familiar with Jinja, so this answer might not be the most efficient one.

            By using basic hard coding in your Template.HTML file, I was able to achieve the results you are trying to. For this, I used the same code that was given by D-E-N in your previous question.

            I combined all the attributes of your object into a string

            • An attribute is differentiated from another with @ (like Course and Teacher)
            • Instead of using space character, I used a _ character to represent space character in the attributes.
            • If one slot contains multiple objects, they are differentiated with space character (just like in the code provided by D-E-N)
