Application Accelerator Software

NVIDIA® is all about data acceleration. With the right tool an application can effectively use server resources and reach extremely low latency and unparalleled throughput performance. Selecting the right tool for your application is the most important step to utilizing your server to the fullest.



DPDK is a set of libraries and optimized NIC drivers for fast packet processing in user space. DPDK provides a framework and common API for high speed networking applications. NVIDIA is part of the DPDK open source community, contributing not only to the development of high performance Mellanox drivers but also by improving and expanding DPDK functionalities and use cases.

HPC-X ScalableHPC

To meet the needs of scientific research and engineering simulations, supercomputers are growing at an unrelenting rate. The NVIDIA Mellanox HPC-X® Toolkit is a comprehensive MPI and SHMEM/PGAS software suite for high performance computing environments. HPC-X provides enhancements to significantly increase the scalability and performance of message communications in the network.

NVIDIA Mellanox Rivermax

As the Media and Entertainment (M&E) live video broadcasting industry shifts from a Serial Digital Interface (SDI) to IP-based infrastructure, broadcasters are reaping such benefits as production scalability and flexibility. IP-based solutions also addresses the high bandwidth requirement of 4K UHD and 8K UHD video formats.

Messaging Accelerator

The NVIDIA Mellanox Messaging Accelerator (VMA) boosts the performance of message-based and streaming applications across a wide range of industries. These include the Financial Service market's High-Frequency Trading (HFT) platforms, Web 2.0 clusters, and more. For Media and Entertainment broadcasting and streaming (supporting SMPTE 2110-21) please refer to NVIDIA Mellanox Rivermax®.

Unified Communication X

The UCX framework is a collaboration between industry, laboratories, and academia to create an open-source production grade communication framework for data centric and high-performance applications. UCX is performance oriented for low-overheads in communication path allowing near native-level performance while enabling cross platform unified API supporting various network Host Card Adapters (HCAs) and processor technologies (x86, ARM and PowerPC). UCX is part of the HPC-X® ScalableHPC Software Toolkit.
