4.9.3. Networking support / options
The following are command line options for various network types that
can be used with configure
:
--with-fca=DIR
: Specify the directory where the Mellanox FCA library and header files are located.FCA is the support library for Mellanox switches and HCAs.
--with-hcoll=DIR
: Specify the directory where the Mellanox hcoll library and header files are located. This option is generally only necessary if the hcoll headers and libraries are not in default compiler/linker search paths.hcoll is the support library for MPI collective operation offload on Mellanox ConnectX-3 HCAs (and later).
--with-knem=DIR
: Specify the directory where the knem libraries and header files are located. This option is generally only necessary if the knem headers and libraries are not in default compiler/linker search paths.knem is a Linux kernel module that allows direct process-to-process memory copies (optionally using hardware offload), potentially increasing bandwidth for large messages sent between messages on the same server. See the Knem web site for details.
--with-libfabric=DIR
: Specify the directory where the OpenFabrics Interfaceslibfabric
library and header files are located. This option is generally only necessary if the libfabric headers and libraries are not in default compiler/linker search paths.Libfabric is the support library for OpenFabrics Interfaces-based network adapters, such as Cisco usNIC, Intel True Scale PSM, Cray uGNI, etc.
--with-libfabric-libdir=DIR
: Look in directory for the libfabric libraries. By default, Open MPI will look inDIR/lib
andDIR/lib64
, which covers most cases. This option is only needed for special configurations.--with-portals4=DIR
: Specify the directory where the Portals4 libraries and header files are located. This option is generally only necessary if the Portals4 headers and libraries are not in default compiler/linker search paths.Portals is a low-level network API for high-performance networking on high-performance computing systems developed by Sandia National Laboratories, Intel Corporation, and the University of New Mexico. The Portals 4 Reference Implementation is a complete implementation of Portals 4, with transport over InfiniBand verbs and UDP.
--with-portals4-libdir=DIR
: Location of libraries to link with for Portals4 support.--with-portals4-max-md-size=SIZE
and--with-portals4-max-va-size=SIZE
: Set configuration values for Portals 4--with-psm=<directory>
: Specify the directory where the QLogic InfiniPath / Intel True Scale PSM library and header files are located. This option is generally only necessary if the PSM headers and libraries are not in default compiler/linker search paths.PSM is the support library for QLogic InfiniPath and Intel True Scale network adapters.
--with-psm-libdir=DIR
: Look in directory for the PSM libraries. By default, Open MPI will look inDIR/lib
andDIR/lib64
, which covers most cases. This option is only needed for special configurations.--with-psm2=DIR
: Specify the directory where the Intel Omni-Path PSM2 library and header files are located. This option is generally only necessary if the PSM2 headers and libraries are not in default compiler/linker search paths.PSM is the support library for Intel Omni-Path network adapters.
--with-psm2-libdir=DIR
: Look in directory for the PSM2 libraries. By default, Open MPI will look inDIR/lib
andDIR/lib64
, which covers most cases. This option is only needed for special configurations.--with-ucx=DIR
: Specify the directory where the UCX libraries and header files are located. This option is generally only necessary if the UCX headers and libraries are not in default compiler/linker search paths.--with-ucx-libdir=DIR
: Look in directory for the UCX libraries. By default, Open MPI will look inDIR/lib
andDIR/lib64
, which covers most cases. This option is only needed for special configurations.--with-usnic
: Abort configure if Cisco usNIC support cannot be built.
