[libfabric-users] The OpenFabrics Alliance Announces the Release of libfabric v2.5.0

[newsletters at openfabrics.org]

The OpenFabrics Alliance, the OpenFabrics Interfaces Working Group, and the
libfabric community are pleased to share that libfabric 2.5.0 is now available.

This version continues the Open_Fabrics_Interfaces_(OFI) framework's transition
into the 2.x series, focusing on optimizations for high-performance computing
(HPC) and the Ultra_Ethernet_Consortium_(UEC).
Key Updates in Version 2.5.0

The 2.5.0 release introduced several core framework improvements and provider-
specific enhancements:
    * Core Framework & Logging:
    * Added a log_location parameter, allowing users to redirect logs directly
      to a file.
    * Fixed hugepage count calculations and added missing fields to fi_info
      output.
    * Clarified in documentation that failed fi_inject calls will generate
      error completion queue entries (CQEs).
    * Enables 32-bit build support.
    * Heterogeneous Memory (HMEM):
    * Added support to query Neuron operations versions and integrated neuron
      nrt_get_dmabuf_fd_v2 where available.
    * Updated logic to use NVML device counts when determining whether to use
      Inter-Process Communication (IPC).
    * Platform Support:
    * Expanded Windows compatibility by adding definitions for PATH_MAX and
      mode_t.
    * Added unified OS abstraction functions such as ofi_open, ofi_fdopen, and
      ofi_close.
    * Providers:
    * New architecture for the shm provider.
    * Update the psm3 provider to match Intel(R) Ethernet Fabric Suite (IEFS)
      12.1.0.1.
    * Various fixes and improvements.
 
About libfabric

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.

Libfabric source packages are available at: https://github.com/ofiwg/libfabric/
