Open Fabrics BOF - Introduction
Open Fabrics“The mission of the OpenFabrics Alliance (OFA) is to develop,
distribute and promote a unified, transport-independent, open-source software stack for RDMA-capable fabrics and networks, including InfiniBand and Ethernet “
Support for both Microsoft Windows and Linux Development happens using a typical open source development
model• Developer’s Working Group
• code developed and reviewed using email lists
Validation and release by the Enterprise Working Group and the Windows Working Group
• OFED – for Linux• WinOF – for Windows
