The three kinds of memory allocations and their characteristics are summarized in the table below. No explicit copy is necessary for synchronizing between the host and the device, but it is needed for other devices in the context. ![]() The data can migrate (operated by the Level-Zero driver) between the host and the device for faster access. No explicit copy is needed for synchronizing of the data with the host or devices.Īllocation can be accessed by the host and the specified device only. ![]() The data stays on the host all the time and is accessed via PCI from the devices. The data stays on the device all the time and thus is the fastest choice for kernel execution.Įxplicit copy is needed to transfer data to the host or other devices in the context.Īllocation can be accessed by the host and any other device in the context. There are three ways to allocate memory in SYCL:Īllocation can only be accessed by the specified device but not by other devices in the context nor by host. Unified Shared Memory (USM) allows a program to use C/C++ pointers for memory access.
