WebThe shared local memory (SLM) in Intel ® GPUs is designed for this purpose. Each X e -core of Intel GPUs has its own SLM. Access to the SLM is limited to the VEs in the X e -core or work-items in the same work-group scheduled to execute on the VEs of the same X e -core. It is local to a X e -core (or work-group) and shared by VEs in the same X ...
On devices of compute capability 2.x and 3.x, each multiprocessor has 64KB of on-chip memory that can be partitioned between L1 cache and shared memory.
