Webb29 maj 2016 · Shared virtual memory (SVM) allows processors to see the same view of memory; specifically, the same virtual address on the CPU and GPU will point to the same physical memory location. With this architecture, an application only needs to pass a pointer between processors that are sharing data. WebbDescription. Shared Virtual Memory (SVM) (Glossary): An address space exposed to both the host and the devices within a context. 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. It logically extends a portion of the ...

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.
