Nvidia patents system to share computer memory between operating systems

Nvidia describes a method where different operating systems can share specific sections of computer memory using a unique identifier called a handle. This allows hardware accelerators, like graphics chips, to access that shared memory directly without copying the data to local storage first.

Why it mattersThis could make high-performance computing more efficient by reducing the time it takes to move data between different software environments.

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: receive a handle generated in response to an application programming interface (API) call, the handle identifying a portion of storage used by a first operating system instance; cause a 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.
