Nvidia patents way for computer parts to share memory without copying

Nvidia has filed a patent for a software method that lets different parts of a computer system share the same memory space. It uses a specific identifier, called a handle, to allow hardware components to access data directly from another part of the system instead of copying it to local storage.

Why it mattersThis could make computers run faster and use less energy by reducing the need to move data around, which is useful for heavy tasks like video editing or scientific computing.

In the filing’s own words

Apparatuses, systems, and techniques to share portions of storage across operating system instances. In at least one embodiment, one or more APIs are performed to cause a portion of storage used by a first operation system instance to be shared with a second operation system instance using a handle identifying the portion of storage.

What exactly they claim (claim 1)

1. One or more processors comprising circuitry to: generate a handle identifying a portion of storage used by a first operating system instance; cause the handle to be shared with a second operating system instance; cause the second operating system instance to map the portion of storage based, at least in part, on the handle; and cause an accelerator associated with the second operating system instance to directly access the portion of storage without storing data locally.
