 Some Notes On Pre-stage Scheduling For iPadOS 16

① About pre-stage scheduling.

The realization of this function requires two necessary conditions, the first is M1. Not expanded in the video, here the iPad uses the M1’s virtual swap memory technology.

What does this technique mean? How is it different from traditional background multitasking?

Due to the unified memory design, front-end scheduling allows each application to use the iPad’s theoretical maximum memory. In the multitasking background of iPadOS 15, if I use the iPad Air 5 to run four applications in the background at the same time, the four applications can use a total of 8GB of memory. Assuming an average score, each application can use 2GB of memory, and the application design has a very low memory limit.

In iPadOS 16, if four applications are run in the front-end scheduling, each application can use up to 8GB of memory through virtual memory swap.

Note ⚠️ is that each application can use all the memory, and at the same time, it can also be presented in the form of multi-tasking.

This is the function realized by the M1 chip, and it is also the core big trick hidden behind the seemingly multitasking.

The second condition required is the display zoom mode, which supports manual selection of the size and display ratio of the application window. Multi-level adjustment between desktop landscape state and mobile phone portrait state.

② For iPad Pro with 1TB storage or 2TB storage, each application can use up to 16GB of memory through pre-stage scheduling.

At present, few applications need to eat 16GB of memory alone, but this is the foundation for the arrival of desktop-level applications.

③ It is 100% certain that front-of-stage scheduling is the future of iPad multitasking.

I’m not sure if the existing tiled multitasking form will be retained in the future, but Apple will definitely pour more resources into front-end scheduling.

So this update is basically a watershed. The M1 chip is distinguished from the equipment before M1.

④ The pre-stage scheduling should be after Apple added one-screen dual tasks, added the magic keyboard, supported the cursor operation of the trackpad and mouse, and equipped with computer-level chips, once again further blurring the boundaries between iPads and desktop computers.
