摘要:
A method, system, and computer program product are disclosed for providing improved access to accelerated processing device compute resources to user mode applications. The functionality disclosed allows user mode applications to provide commands to an accelerated processing device without the need for kernel mode transitions in order to access a unified ring buffer. Instead, applications are each provided with their own buffers, which the accelerated processing device hardware can access to process commands. With full operating system support, user mode applications are able to utilize the accelerated processing device in much the same way as a CPU.

摘要:
Disclosed herein are systems, apparatuses, and methods for enabling efficient reads to a local memory of a processing unit. In an embodiment, a processing unit includes an interface and a buffer. The interface is configured to (i) send a request for a portion of data in a region of a local memory of an other processing unit and (ii) receive, responsive to the request, all the data from the region. The buffer is configured to store the data from the region of the local memory of the other processing unit.

In an embodiment, a method of processing memory requests in a first processing device is provided. The method includes generating a memory request associated with a memory address located in an unpinned memory space managed by an operating system running on a second processing device; and responsive to a determination that the memory address is not resident in a physical memory, transmitting a message to the second processing device. In response to the message, the operating system controls the second processing device to bring the memory address into the physical memory.
