FLAT Mode Programming
As mentioned previously, the FLAT mode is the default mode on Intel® Data Center GPU Max Series. In FLAT mode, each stack is exposed as a root device. In this section, we present SYCL and OpenMP examples to demonstrate offloading in FLAT mode.
Memory in FLAT Mode
Each stack has its own memory. A kernel offloaded to a stack will run on that stack and use the memory allocated on that stack.
A kernel running on a stack can access memory on other stacks in the same GPU card. However, accessing memory on a stack other than the stack it is running on will be slower.
