This is a long-term support (LTS) release. LTS is the practice of maintaining a software product for an extended period of time (up to three years) to help increase product stability. LTS releases include bug fixes and security patches.
Overview
The NVIDIA® Messaging Accelerator (VMA) library accelerates latency-sensitive and throughput-demanding TCP and UDP socket-based applications by offloading traffic from the user-space directly to the network interface card (NIC) or Host Channel Adapter (HCA), without going through the kernel and the standard IP stack (kernel-bypass).
VMA leverages the following benefits:
- Implements the legacy POSIX socket interface
- Increases:
- Throughput
- Packets per Second (PPS)
- Requests per Second (RPS)
- Reduces:
- Network latency
- The magnitude of network latency spikes
- Context switches and interrupts
- Network congestion
- Data copying and moving in unicast and multicast applications
- Improves CPU utilization
- Compatible with Ethernet
VMA can work on top of MLNX_OFED driver stack and on a lighter driver stack, MLNX_EN.
Intended Audience
- Market data professionals
- Messaging specialists
- Software engineers and architects
- Systems administrators tasked with installing/uninstalling/maintaining VMA
- ISV partners who want to test/integrate their traffic-consuming/producing applications with VMA
