WebbFör 1 dag sedan · Shared Virtual Memory that was added in OpenCL 2.0 allows for the host and GPU device to easily share pointers and other pointer-based data structures. SVM's shared virtual address space also lays out requirements around coherent access, synchronization, and other functionality that opens up OpenCL for more use cases. WebbShared Virtual Memory (SVM) can considerably simplify the application development for FPGA-accelerated computers, as it allows the seamless passing of virtually Efficient Physical Page Migrations in Shared Virtual Memory Reconfigurable Computing Systems IEEE Conference Publication IEEE Xplore

Currently on Haswell, and older, even though video memory and general cpu memory come off of the same physical chips or DIMMs, they are partitioned effectively from the software developers perspective:
Webb22 dec. 2024 · 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.
Webbdue to separate address spaces by introducing shared virtual memory (SVM), an address space that is shared between host and device. In SVM, pointers assigned on the host can be seamlessly dereferenced on the device side and vice versa and address the same data in this case.
