The Accelerator work group will be a persistent, standing group that defines, documents, manages, and maintains standards which define the interfaces between the processor and accelerator devices and their associated development tools. This includes hardware, firmware and any other software require for accelerators to operate within OpenPOWER compliant systems. It will also identify future requirements and propose innovations to the interfaces to enable advances in accelerator capabilities and work with other working groups as appropriate.

Discussion group for information exchange among OpenPOWER members from academia.

The Accelerated Application Ecosystem Requirements Work Group (AccAppReq WG) is collecting and dispositioning the list of tools, libraries, frameworks and other components/resources needed in the OpenPOWER software ecosystem to ensure that accelerated applications support OpenPOWER servers.  These requirements are being collected from actual ISVs who either have or considered porting and/or developing on the platform.

The OpenPOWER Compliance Work Group will define OpenPOWER key interfaces that need to be compliant in a standard specification of compliance and define how to measure and document compliance pre-silicon and post-silicon.

Subcommittees for each set of related key interfaces will be formed to address reference test harnesses and reference test suites.  This will allow for focused effort by the experts and interested members of the related key interfaces.  The importance of this Work Group is to be able to maintain software and hardware interoperability through following the compliance specifications.

This work group is a persistent WG focused on the ongoing development of OpenPOWER System Hardware Architecture Specifications. Specifications included in, but not limiting the scope will be the OpenPOWER Profile of the POWER ISA, the IO Device Architecture (IODA), and the Coherent Accelerator Interface Architecture (CAIA). The OpenPOWER Profile is defined as the subset of instructions and features of the POWER ISA required to support the OpenPOWER ecosystem. The IO Device Architecture describes the “host bridge” functions / interface support for IO Devices, for example PCIe Host Bridge. CAIA describes the interface to the Operating System (OS) by defining how the OS should work with a Coherent Accelerator Processor Interface (CAPI) Device attached tothe Power Service Layer (PSL).

The OpenPOWER Machine Learning Work Group provides a forum for collaboration that will help define frameworks for the productive development and deployment of machine learning solutions using OpenPOWER ecosystem technology.

As part of the ecosystem, the OPMLWG plays a crucial role in expanding the OpenPOWER mission.  It focuses on addressing the challenges machine learning project developers are continuously facing by identifying use cases, defining requirements and extracting workflows, to better understand processes with similar needs and pain points. The working group will also identify and develop technologies for the effective execution on machine learning applications by enabling hardware (HW), software (SW) and acceleration across the OpenPOWER ecosystem.

The OpenPOWER Memory work group is a persistent, standing group that defines, documents, manages and maintains the interface requirements (protocol, timing, etc.) between the OpenPOWER Processor Memory Channel which provides a common intermediate interface to memory controllers that attach to physical memory. It will also identify which type of memory technology and ensure that the interface will be compatible, suitable with OpenPOWER Memory Bus. Since this work group affects the area of both hardware and software in the OpenPOWER ecosystem, it is expected that its activities will be related to the activities of the

1. Compliance WG
2. Industry standard body
3. Hardware Development platform WG
4. System Software WG

Leadership and management of all aspects of the OpenPOWER Ready Program. Key aspects are the OpenPOWER Ready Definition and Criteria, review of OpenPOWER Ready requests, and outreach to encourage participation.

This Work Group aims at addressing the challenges of Physical Science projects by developing use cases, identifying requirements and extracting workflows, to better understand common workflows with related needs and pain points.

Discussion Group for the suggestion and development of potential technical work group topics.

The Systems Software work group will serve as the stewards, incubators, and drivers (when feasible) of system software enablement for OpenPOWER Foundation hardware.  As such, the work group will work to ensure the availability of all software required to boot, run, and manage Linux on OpenPOWER compliant systems.  This includes platform firmware, virtualization environments, Linux itself, toolchain (compilers, core libraries, debuggers, etc.) and platform management software.  This does not include software specifically used to enable end user application execution. The goal for all software is availability under an appropriate open source license.
