This is the userspace components for the Linux Kernel's drivers/infiniband subsystem. Specifically this contains the userspace libraries for the following device nodes:
The userspace component of the libibverbs RDMA kernel drivers are included under the providers/ directory. Support for the following Kernel RDMA drivers is included:
Additional service daemons are provided for:
This project uses a cmake based build system. Quick start:
$ bash build.sh
build/bin will contain the sample programs and build/lib will contain the shared libraries. The build is configured to run all the programs 'in-place' and cannot be installed.
NOTE: It is not currently easy to run from the build directory, the plugins only load from the system path.
$ apt-get install build-essential cmake gcc libudev-dev libnl-3-dev libnl-route-3-dev ninja-build pkg-config valgrind python3-dev cython3 python3-docutils pandoc
$ dnf install cmake gcc libnl3-devel libudev-devel pkgconfig valgrind-devel ninja-build python3-devel python3-Cython python3-docutils pandoc
NOTE: Fedora Core uses the name 'ninja-build' for the 'ninja' command.
$ zypper install cmake gcc libnl3-devel libudev-devel ninja pkg-config valgrind-devel python3-devel python3-Cython python3-docutils pandoc
Install required packages:
$ yum install cmake gcc libnl3-devel libudev-devel make pkgconfig valgrind-devel
Developers on CentOS 7 or Amazon Linux 2 are suggested to install more modern tooling for the best experience.
$ yum install epel-release $ yum install cmake3 ninja-build pandoc
Amazon Linux 2:
$ amazon-linux-extras install epel $ yum install cmake3 ninja-build pandoc
NOTE: EPEL uses the name 'ninja-build' for the 'ninja' command, and 'cmake3' for the 'cmake' command.
To set up software RDMA on an existing interface with either of the available
drivers, use the following commands, substituting
<DRIVER> with the name of
the driver of your choice (
<TYPE> with the type
corresponding to the driver (
# modprobe <DRIVER> # rdma link add <NAME> type <TYPE> netdev <DEVICE>
Please note that you need version of
iproute2 recent enough is required for the
command above to work.
You can use either
rdma link to verify that the device was
