From newsletters at openfabrics.org Thu Dec 19 14:50:36 2024 From: newsletters at openfabrics.org (newsletters at openfabrics.org) Date: Thu, 19 Dec 2024 14:50:36 -0800 (PST) Subject: [OFIWG-MPI] The OpenFabrics Alliance Announces the Release of libfabric v2.0.0 Message-ID: <1734648636.2142179@openfabrics.org> The OpenFabrics Alliance Announces the Release of libfabric v2.0.0 The OpenFabrics Alliance, the OpenFabrics Interfaces Working Group, and the libfabric community are pleased to announce the release of version v2.0.0 of libfabric and fabtests. Libfabric, also known as Open Fabrics Interfaces (OFI), is a framework focused on exporting high-performance networking services to applications. It specifically targets parallel and distributed applications and middleware. Libfabric is designed to minimize the impedance mismatch between applications, middleware and fabric communication hardware. Its interfaces target high- bandwidth, low-latency NICs, with a goal to scale to tens of thousands of nodes. Libfabric is supported by a variety of open source HPC middleware applications, including MPICH, Open MPI, Sandia SHMEM, Open SHMEM, Charm++, GasNET, Clang, UPC, DAOS, and others. The release of libfabric 2.0 is an important milestone for libfabric as it simplifies and tunes the API in preparation for Ultra Ethernet Consortium (UEC). Unsupported features have been deprecated, and some features have been replaced with more optimal ones to encourage adoption of the new standard. New features, such as standardized tag formats, new atomic types target for AI, and stabilization of inter-provider usage have been added, allowing for more fine-tuned focus on AI and offloaded accelerations. The software for the Ultra Ethernet Transport is based on libfabric v2.0 APIs, targeting both HPC and AI fabrics (See [1]https://ultraethernet.org/ultra-ethernet-specification-update/). Libfabric source packages are available at: [2]https://github.com/ofiwg/libfabric/releases/tag/v2.0.0.
