XLIO - Accelerated IO SW library

The NVIDIA® Accelerated IO (XLIO) SW library boosts the performance of TCP/IP network applications providing high bandwidth and low CPU usage. XLIO is a user-space software library which exposes standard POSIX and XLIO Ultra socket APIs with kernel-bypass architecture, enabling a hardware-based direct copy between an application user-space memory and the network interface.

Coupling XLIO with Crypto Enabled NVIDIA ConnectX, NVIDIA BlueField data processing unit (DPU) acceleration capabilities, provides a breakthrough performance of Transport Layer Security (TLS) encryption and decryption. XLIO is capable of utilizing HW features such as LRO/TSO and Striding-RQ which increase TCP performance, without application code changes for both POSIX socket and XLIO Ultra APIs.

Getting Started

Installing XLIO

XLIO is available as part of DOCA Software Stack. Please visit DOCA website for more details.

Building XLIO

Prerequisits

DOCA Software stack

XLIO requires NVIDIA DOCA-Host software stack or NVIDIA Bluefiled bundle to be installed on the system. Please visit DOCA website for more details.

DPCP

DPCP (Direct Packet Control Plane) is mandatory to run XLIO. Repository: libdpcp

$ ./autogen.sh
$ ./configure --prefix=/where/to/install
$ make -j
$ make install

Tools

Autoconf, Automake, libtool, unzip, patch, libnl-devel (netlink 3)

Compiling XLIO

Run the following commands from within the directory at the top of the tree:

$ ./autogen.sh
$ ./configure --prefix=/where/to/install --with-dpcp=/where/dpcp/installed --enable-utls
$ make -j
$ make install

--enable-utls : Enables uTLS HW offload for supported NVIDIA HW.

Compiling XLIO using preinstalled dpcp

$ ./autogen.sh
$ ./configure --prefix=/where/to/install --with-dpcp --enable-utls
$ make -j
$ make install

Usage Examples

Sockperf

LD_PRELOAD=libxlio.so sockperf <params>

Reposiroty: Sockperf

nginx

LD_PRELOAD=libxlio.so XLIO_NGINX_WORKERS_NUM=<N> nginx <nginx_params>

N - Number of Nginx workers.
