IBM: OpenPOWER Foundation, Savings and the OpenStack Platform

  • OpenPOWER Foundation | The Next Step in the OpenPOWER Foundation Journey

    Today marks one of the most important days in the life of the OpenPOWER Foundation. With IBM announcing new contributions to the open source community including the POWER Instruction Set Architecture (ISA) and key hardware reference designs at OpenPOWER Summit North America 2019, the future has never looked brighter for the POWER architecture. OpenPOWER Foundation Aligns with Linux Foundation The OpenPOWER Foundation will now join projects and organizations like OpenBMC, CHIPS Alliance, OpenHPC and so many others within the Linux Foundation. The Linux Foundation is the premier open source group, and we’re excited to be working more closely with them. Since our founding in 2013, IEEE-ISTO has been our home, and we owe so much to its team. It’s as a result of IEEE-ISTO’s support and guidance that we’ve been able to expand to more than 350 members and that we’re ready to take the next step in our evolution. On behalf of our membership, our board of directors and myself, we place on record our thanks to the IEEE-ISTO team. By moving the POWER ISA under an open model – guided by the OpenPOWER Foundation within the Linux Foundation – and making it available to the growing open technical commons, we’ll enable innovation in the open hardware and software space to grow at an accelerated pace. The possibilities for what organizations and individuals will be able to develop on POWER through its mature ISA and software ecosystem will be nearly limitless.
