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

BACKGROUND MATERIAL

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


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
