At the ongoing North American OpenPOWER Summit, IBM announced the Open Source Power Chip Instruction Set Architecture (ISA).
IBM also promotesOpenPOWER Foundation joined the Linux Foundation。OpenPOWER FoundationEstablished by Google, Mellanox Technologies, Nvidia and Tyan, this is an open technology community based on Power Architecture to promote and encourage collaborative innovation based on Power Architecture. OpenPOWER members share experience, investment and server-level intellectual property to develop solutions to meet the evolving needs of technology customers. The OpenPOWER Foundation supports members to customize Power processors, system platforms, firmware and middleware software for optimization to meet their business and organizational needs.
The OpenPOWER Foundation, which operates under the Linux Foundation, will have an open governance model, and IBM will have the same voting rights as other OpenPOWER Foundation members on what changes power ISA can make in the future. IBM will reserve the right to make any changes to the Power architecture to meet its own needs, but all other changes require a majority vote of members to ensure compatibility. AcceptanceInterview with NextplatformKen King, general manager of OpenPower at IBM, said:
In addition, IBM has contributed to the community a PowerISA soft core model that has been implemented on the FPGA.
It is worth noting that in November last year, the Linux Foundation and the RISC-V Foundation announced a cooperative promotion of RISC-V. Now the OpenPOWER Foundation has become part of the Linux Foundation. The Linux Foundation will also focus on promoting the Power architecture. Under the same foundation, how can RISC-V and Power coexist?
Hugh Blemings, Executive Director of the OpenPOWER Foundation, said that these two ISAs usually have different use cases. Although RISC-V is a newly emerging open source instruction set, it is mainly used in the field of IoT and still not suitable for high performance computing. Server processor based on ARM instruction set has been launched, but it will take some time to build software ecology. This time IBM officially opened source Power instruction set, this mature instruction set will attract the attention of the field of high-performance computing.
