3. THE HSA FOUNDATION: ACTIVITIES
 Nonprofit, open standardization body for HSA platforms that will own the
architecture going forward
 Make heterogeneous programming easy and a first-class pervasive
complement to CPU computing
 Increase power efficiency of HSA to make it the platform of choice from
smartphones to the cloud
 Bring to market strong development solutions (tools, libraries, OS runtimes)
to drive innovative advanced content and applications
 Foster growth of heterogeneous computing talent through HSA developer
training and academic programs to drive both learning and innovation

9. WHAT HSA IS EXTREMELY GOOD AT
 What GPUs do well today
 Data Parallelism - Embarrassingly Parallel Application
 SPMD – Single Program Multiple Data
 MPMD - Multiple Program Multiple Data
 Efficient with kernels with the following memory transfer dependencies:
 Non-dependent
 Dependent –Streaming
 Single Dependent- Host to Device
 Single Dependent- Device to Host
 Dual Dependent
 Plus a much richer set of Parallel Solutions
 Task-Parallelism
 Nested-Parallelism
 Braided-Parallelism
 Irregular Parallelism

10. WHAT HSA IS EXTREMELY GOOD AT
 Parallel problems that are communication intensive
 Need high bandwidth low latency interconnects
 Examples
 SolutionS that are parallelizable by domain decomposition
 Partial differential equations on a regular grid using discrete time stepping
 More efficient implementation of MapReduce, Hash Tables, Sparse Matrix Vectors
and Conjugate Gradients solvers, FETI-DP Method, List Ranking, and spatial search
 Algorithms that need inter-task communication
 Applications that need branching support
 Applications that need exceptions processing
 Dynamic load balancing tasks between processing elements
 Lower kernel launch times
