cpu – Macbook Pro fan running full speed, activity monitor shows no computationally intensive applications

My 2018 Macbook pro 15 inch fan is running at full speed all the time. I checked activity monitor and my idle was >95%. If this is a hardware problem, is there any way to fix it without opening up the whole computer? Otherwise, are there any easy fixes? Thanks

compute shader – Unity: execution of GPU intensive operations in editor mode

I have written an erosion simulator that I want to run from the editor (to generate terrain and such outside the game mode). Unfortunately, when I start the parameters in my simulation, the unit hangs. The user interface stops responding, none of the menus work anymore. However, the process is still running: Windows does not claim that the program no longer responds.

The strange thing is that the task manager claims that the GPU is in zero use while Unity crashes. My erosion code (CPU side) looks more or less like this (executed through the editor script):

    HydraulicCompute.SetFloat("_ErosionRadius", ErosionRadius);
    HydraulicCompute.SetBuffer(_erosionId, "HeightMap", heightMap);
    HydraulicCompute.SetBuffer(_erosionId, "Droplets", _dropletBuffer);

    int threadGroupsX = Mathf.CeilToInt(mapSize / 8.0f);
    int threadGroupsY = Mathf.CeilToInt(mapSize / 8.0f);
    for (int i = 0; i < 100; i++) {
        HydraulicCompute.Dispatch(_dropletId, Mathf.CeilToInt(_dropletBuffer.count / 1024.0f), 1, 1);
        HydraulicCompute.Dispatch(_erosionId, threadGroupsX, threadGroupsY, 1);
    }

When the size of the _dropletBuffer is greater than 12,000 (32 bytes per drop), and the heightMap buffer larger than 1024x1024 (4 bytes per pixel), then I find the problem mentioned above.

I guess the problem occurs because there is a problem with the buffer sizes or the frame takes too long and Unity times out.

When I comment on Dispatch Unity calls are able to assign and fill buffers instantly (at least it seems very fast). While that does not exclude the possible buffer problem, it certainly makes it less likely.

So what exactly is the problem here? Is it a memory problem? Or is the frame running out? Or something completely different?

Is there a prescribed way to do this kind of intensive GPU work in the background in editor mode? I have looked at the Job system, but that seems to be only on the CPU side ...

agile: how to set up and change a hardware intensive company to a software intensive company with respect to platforms and software environment?

I am starting to work in a company. In this company, we have a set of products. These products are inherently related and have many functionalities and shared parts. Each of our products consists of a series of components. The types of these components are small software codes, electronic boards and mechanical parts.

After almost fifteen years of developing and implementing these products for many customers, the managers of this company are frustrated with the administration, updating, improvement and development of new related products.

Another important problem is that after these years, they understood that we have to develop our products based on software and not hardware, as they have already been doing. Currently, our products are based on electronic and mechanical components and the software is mainly for controlling hardware devices. Now we have to develop products that can provide more information and features to the user in mobile applications and store data about our devices on servers. In other words, we change the mindset of developing hardware devices with small software codes to software products that control related hardware devices.

Almost all employees are not computer engineering professionals. They have a bachelor's or master's degree in electronics, control or mechanical engineering. My questions are:

1- How should we begin to establish a development system for such a workforce?
?

2- Is there any software development platform such as Rational rose or any other platform that considers version control and artifact management for electronic and mechanical components?

3- Meanwhile, as a very small step towards this goal, they are looking for a tool that allows them to manage documents produced in the development of these products and link them with other documents in the system. It is very good if this tool has version control and change management along with access control.

ruby – How to efficiently process CPU intensive tasks on the background server

I created an audio processing web application using Rails. The user uploads a song to the website. The song is broken down into individual elements and then modified and recombined.

I am using an open source command line tool that is called from the rail controller.

My problem: the processing takes between 2 and 3 minutes and consumes a lot of memory. The browser is in the loading stage for 2 to 3 minutes. And this is only for 1 request from 1 user. I am using the Amazon ec2 t1.large instance simply is not enough.

I am planning to use background processing, but I don't want several requests to work at the same time.

I want the first request to take 3 minutes. Second request to take 3 + 3 minutes. Third request to take 3 + 3 + 3 minutes. Then the website does not fall.

In addition, the audio file is around 40 mb. Is it a good idea to use amazon s3 bucket? Or simply increase the space on the hard drive and store audio files on my server?

The reason why I don't want to use the amazon s3 bucket is because I don't want to transfer each file again from my ec2 instance to the s3 bucket, since it will be added to the latency.

Eric Matthes ex 7.8 intensive Python course

I have trouble doing an exercise in the book & # 39; Intensive course by Eric Matthes Python & # 39 ;. The exercises are as follows:

7.8 – Snack Bar: Create a list called sandwich_orders and fill it with
The names of several sandwiches. Then create an empty list called
snacks. Scroll through the list of sandwich orders with a loop and
show a message for each order, for example, I have prepared your
Tuna sandwich. As each sandwich is prepared, transfer it
to the list of ready sandwiches. After all the sandwiches are
ready, show a message that lists each sandwich prepared.

sandwich_orders = ('frango', 'peru', 'queijo', 'presunto')
finished_sandwiches = ()

    while finished_sandwiches:
        sandwiches = sandwich_orders.pop()
        finished_sandwiches.append(sandwiches)
        for sandwich in finished_sandwiches:
            print('Preparei seu sanduiche de ' + sandwich)

When I execute the file in vscode I answer this:

PS C:UsersPedro MoraesDesktopstuffExerciciospython> & "C:/Users/Pedro Moraes/AppData/Local/Programs/Python/Python38-32/python.exe" "c:/Users/Pedro Moraes/Desktop/stuff/Exercicios/python/lanchonete.py"

Do not "print" anything on the terminal.

That I have to do?

architecture – System design for intensive computing software

I have a use case that will take data from the front end and transform it with several parameters. Then a random effects model is executed in each transformation and multiple models are constructed

For example: the data has 5 independent variables. For each independent variable, about 3 consecutive transformations must be performed and each one has about 10 possible transformation values. The whole space or combination will be (10 ^ 3) ^ 5. But we will only give a smaller subset of values ​​for transformation and modeling, think of it as something similar to the grid search. Therefore, around 10k models will be built per user.

Now the problem I am facing is how to scale this system to multiple users. The AWS server with 64 gigabytes of RAM and 8 cores is significantly stuck with only two users (since the current system is horrible with a monolithic design).

I am a newbie in most of this, so the solution I can find is:

Divide the server into 3, one for application, preprocessing and modeling. This would separate the load and we can assign instances of intensive computation to modeling alone. If it is an acceptable solution, I would love to know how to scale at low cost by design instead of adding more ec2s and cores (have a docker image for each flask server).

How would you do with the modeling server? Do you treat it as a function and send you API calls with the relevant data and make models one by one or in some type of batches? I hope the WSGI (gunicorn) server can be configured to have multiple workers so that it resolves to run multiple models in parallel.

And mongo db is used to save the results. Now, mongo db apparently writes one at a time, so it seems that there is a bottleneck there (if this fact is incorrect, let me try to get the source)

Would lambda or sagemaker be useful for automatic scaling of the modeling part?

Also, let me know of any design or factual errors here.

Thanks in advance!!
