Welcome to OpenCAPI Consortium

The OpenCAPI Consortium is an open forum to manage the OpenCAPI specification and ecosystem. OpenCAPI is a not-for-profit organization formed in October 2016 by OpenCAPI Strategic Members AMD, Google, IBM, Mellanox Technologies and Micron to create an open coherent high performance bus interface based on a new bus standard called Open Coherent Accelerator Processor Interface (OpenCAPI) and grow the ecosystem that utilizes this interface. This initiative is being driven by the emerging accelerated computing and advanced memory/storage solutions that have introduced significant system bottlenecks in today’s current open bus protocols and requires a technical solution that is openly available.

How to become OpenCAPI Ready

The OpenCAPI Ready™ program is used by the OpenCAPI Consortium to enable OpenCAPI ecosystem product developers to indicate that a product has been shown/demonstrated to meet a minimum set of characteristics and should be interoperable with other OpenCAPI Ready products.

OpenCAPI showcases and progress ……

OpenCAPI held its first SNAP (Storage, Network, Analytics and Programming) Hands-on Workshop.  The workshop was an end-to-end educational session where the basic OpenCAPI technology and SNAP demo were presented.  The workshop enabled access to SNAP in a cloud environment so the attendees could give it a spin!
