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. However, OpenCL 2.0 shared virtual memory … Visa mer The following sections describe each of the SVM features. For each feature, a tag in a green box specifies the minimum SVM level required to use … Visa mer With OpenCL 2.0, the support for Shared Virtual Memory (SVM) introduces one of the most significant improvements for the programming model. Previously memory spaces of the host and … Visa mer 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.

Shared Virtual Memory (SVM) Functions

WebbBoost.Compute does support shared virtual memory using the boost::compute::svm_* functions. For your application, you should be able to just allocate a region of SVM memory with svm_alloc(), fill it with your input data, and then pass it to your kernel using the regular kernel::set_arg() function (which has an overload for SVM memory objects). Webb29 aug. 2024 · Shared virtual memory (SVM) is key in heterogeneous systems on chip (SoCs), which combine a general-purpose host processor with a many-core accelerator, both for programmability and to avoid data duplication.
