We allocated memory for our native array.

我们为本机数组分配了内存。

Interestingly, Metal Heaps also allows you to reuse previously allocated memory from textures you don't need simultaneously, which can save you significant amounts of memory per frame.

有趣的是，Metal 堆允许你重新使用你暂时不需要的纹理中的已经被分配的内存，这可以帮你节省大量的每帧内存。

And because it's a native container, we need to allocate memory.

因为它是一个本机容器，所以我们需要分配内存。

Program A might get allocated memory addresses 0 through 999, and Program B might get 1000 through 1999, and so on.

程序 A 可能分配到 0 到 999 的内存地址，程序 B 可能分配到 1000 到 1999，依此类推。

Another upside of allocating each program its own memory, is that they're better isolated from one another.

为每个程序分配自己的内存的另一个好处是它们可以更好地相互隔离。

This can provide a much more efficient way of managing your Metal textures and buffers without requiring you to become an expert in how each individual GPU manages and allocates memory.

它可以提供更高效的办法来管理你们的 Metal 纹理和缓冲区，而不必要求你懂得每一个独立的 GPU 是如何管理和分配内存的。

If a program asks for more memory, the operating system decides if it can grant that request, and if so, what memory block to allocate next.

如果一个程序请求更多的内存，操作系统决定它是否可以授予该请求，如果可以，接下来分配哪个内存块。
