SVM causes addresses to be meaningful between the host and all of the devices within a context and therefore supports the use of pointer based data structures in OpenCL kernels. One of the remarkable features of OpenCL™ 2.0 is shared virtual memory (SVM). This feature enables OpenCL developers to write code with extensive use of pointer-linked data structures like linked lists or trees that are shared between the host and a device side of an OpenCL application. In OpenCL 1.2, the … Visa mer In its purest form, SVM enables CPU and GPU code to share a pointer rich data-structure by simply passing a single root pointer.

Webb4 feb. 2024 · Shared Virtual Memory (SVM)# Shared virtual memory allows the host and the compute device to share address space, so that pointers on the host and on the device may have the same meaning. In addition, it allows the same memory to be accessed by both the host and the device. WebbFor SVM to be used efficiently, the host and any devices sharing a buffer containing virtual memory pointers should have the same endianness. If the context passed to clSVMAlloc has devices with mixed endianness and the OpenCL implementation is unable to implement SVM because of that mixed endianness, clSVMAlloc will fail and return NULL.
