How to utilize all cpu cores in training?

I want to use all available CPU cores in kaggle.

data = TextDataLoaders.from_folder(dest_sample, valid_pct=0.1, is_lm=True, 
                                   tok_tfm=SubwordTokenizer(), seed=42, bs=bs) 
# data.num_workers = 4
# data[0].num_workers = 4
learn = language_model_learner(data, AWD_LSTM, drop_mult=0.1, wd=0.1, 
                                 pretrained=False).to_fp16()
learn.unfreeze()
learn.fit_one_cycle(10, lr, moms=(0.8,0.7))

In gpu machine, which the number of CPU cores is 2, it always shows 100%. Even when I do data.num_workers = 4 it is still 100%. Which means it doesn’t utilizes all CPU cores.

  1. How can I use all CPU cores? Is it right approach data.num_workers = 4 ?
  2. Also why TextDataloaders.from_folder doesn’t have num_workers attribute?

Here is an image. I want CPU usage close to 200%. But it stays at 100%

Considerations for presentations

You’ll need to consider several factors for your presentations, regardless of the type. Understanding these considerations will help your presentations be well-received and more effective with their intended message.

Handle questions and interruptions

Ideally, you’re not the only team member who’s participating in giving the presentation. Likely, another team member will be present to take notes. However, if you’re alone, make sure that note taking is still an important part of your presentation. Note taking is beneficial when you need to pause for audience questions or objections, or to get a presentation back on track when someone sidetracks the conversation with an unrelated digression.

Another benefit of note taking is that you can use it to help with follow-up responses. When faced with a question that you don’t have an immediate answer to, make sure that you repeat or rephrase the question so that you have a solid understanding of it. Then, you can use your detailed notes when researching the answer to the question. Make sure that you follow up as soon as possible after the presentation.

Example

The customer asks, “How fast can those forms load?”

You don’t have an immediate answer, so your response can be, “To clarify, you want to know the load times for the forms from this demo? Do you want to know about other forms as well? I’ll note your questions and follow up with you after this meeting.”

Be a good audience for other presenters

If you’re not leading the presentation, then you’re likely taking notes. In that scenario, make sure that you’re being a good listener, anticipating questions, and taking good notes for follow-up. Keep engaged in the conversation and help the primary presenter if you notice them faltering or speak up if you’re the expert on a topic that’s being discussed and questioned.

Presentation format

A presentation doesn’t necessarily involve you standing in front of an audience with a PowerPoint slide deck.

Instead, tailor your presentation to fit your style, the audience, and the topic. Your presentation can include a variety of approaches:

  • Use a whiteboard to draw pictures or diagrams.
  • Show a video to demonstrate the product or process.
  • Conduct a workshop, where you gather information from your customers.
  • Provide a live demonstration of your design document.
  • Show a PowerPoint-heavy sales presentation.

You can choose to use only one format, or you can switch between the different formats for variety. For example, you might choose to use a PowerPoint slide deck, a live demonstration of the system, and a video of future functionality.

The presentation format can make or break a presentation. Some presenters support the notion that presentations need to include flashy visuals. The truth is that an extravagant presentation can remove focus from the presenter and the message of the presentation. A good presentation can make any presenter look good. A poorly constructed PowerPoint can make any presentation unappealing, regardless of the topic. The success of the presentation is dependent on who’s presenting, how they present the topic, and how the format backs up the presentation.

Audience

It’s important to know who you’re presenting to. Your audience is extremely important and should dictate how you’ll deliver your presentation. Make sure that you adjust your presentation to fit your audience.

For example, you’ll want to have different presentations for the executive management and for your users. The executive management team might not want to know how the different technical solutions in your system work, whereas your users will. Similarly, presenting internally to the project team will differ from presenting to someone who’s not involved in the project at all.

How good your presentation is doesn’t matter if it’s not adjusted to the right audience. Consider a scenario where you’ve given a presentation on Microsoft Dynamics 365 Supply Chain Management. From your perspective, the presentation seemed to go smoothly and was a great success. However, on receipt of the post-presentation survey, you’ve discovered that your customer is extremely dissatisfied. Later, after you’ve received more requirements from the customer, you realize that they’re looking for a finance system, not a system for their supply chain. If you would have given a demonstration of Microsoft Dynamics 365 Finance, then the customer would most likely be happy.

Delivering the right content to the right audience is imperative.

Planned or spontaneous

Planned and spontaneous presentations differ significantly. A planned presentation takes considerable time in creating and planning before the actual presentation, whereas a spontaneous presentation happens instantaneously. Planned presentations can include a demonstration of the proof of concept that you’ve created and want the customer to approve. Conversely, with a spontaneous presentation, you might explain a new feature to a user who happens to walk into your office.
