AN N-DIMENSION DOMAIN OF WORK-ITEMS Global Dimensions: 1024 x 1024 (whole problem space) Local Dimensions: 128 x 128 (work group … executes together) 1024 1024 20 | Making OpenCL Simple | January, 2011 | Public Synchronization between work-items possible only within workgroups: barriers and memory fences Cannot synchronize outside of a workgroup • Choose the dimensions that are “best” for your algorithm
OPENCL MEMORY MODEL •Private Memory –Per work-item •Local Memory –Shared within a workgroup •Global/Constant Memory –Visible to all workgroups •Host Memory –On the CPU Memory management is Explicit You must move data from host -> global -> local … and back 21 | Making OpenCL Simple | January, 2011 | Public Private Memory Work- Item Workgroup Work- Item Compute Device Host Private Memory Local Memory Private Memory Work- Item Local Memory Workgroup Global/Constant Memory Host Memory Private Memory Work- Item
