Working Groups drive the future of HSA technology

The HSA Foundation’s working groups address the HSA architecture, hardware, and software needed to execute an HSA system.

• HSA Systems Architecture Working Group
•  Group Chair: Paul Blinzer, AMD
• Describes hardware and software requirements such as cache coherent shared virtual memory, architected queuing language formats, agent scheduling, forward progress rules, IEEE754-2008 exceptions, kernel agent debug infrastructure, platform topology discovery, images, profiling interface, and the memory consistency model
• HSA Software Working Group
• Group Chair: Andrew Richards, Codeplay Software Ltd.
• HSA Programmer’s Reference Manual: HSAIL virtual ISA and programming model, parallel synchronization and communications, compiler writer’s guide, and object format (BRIG)
• HSA Runtime Specification: Programming model, initialization and agent discovery, signals API, queues API, AQL packet formats, memory API, code object loading, HSAIL finalization API, images and samples API, and the profiling API
• HSA Multivendor Sub-Working Group
  •  Group Chair: Roy Ju, Mediatek
  • Describes a method for SoC vendors to design hw and sw for HSA compatibility permitting HSA implementations using IP from multiple vendors that is portable between implementations
  • Allows system wide signalling, task dispatch to queues between agents of different vendors, and standardizing communication between software components
• HSA Compliance Working Group
• HSA Marketing Working Group
  •  Group Chair: Ran Zhou, General Processor Technologies
