Alveo U55C Card Acceleration in Action


Real-Time Results on Graph Databases

When TigerGraph, the world’s most scalable graph database, needed to accelerate their graph database analytics solution, they turned to Xilinx.

Graph Database Analytics Acceleration


Graph databases are great for connecting siloed data to gain valuable insights. If you have a graph database, you know the best way to get your answers fast, is through acceleration.

The Alveo U55C card is able to accelerate query times and predictions for recommendation engines from minutes down to milliseconds. The U55C’s superior computational power and memory bandwidth enable graph query speeds up to 96x faster compared to CPU-based clusters, while increasing the quality of scores by up to 35%.

This improvement results in greater confidence, dramatically lowering false positives to low single digits. ​

TigerGraph, the world’s most scalable graph database, turned to Xilinx to accelerate their software-based graph analytics solution.

Utilizing multiple Alveo U55C cards, TigerGraph tapped into Xilinx’s massive clustering ability to accelerate the two most prolific algorithms that drive graph-based recommendation engines:  Cosine Similarity and Louvain Modularity.


Product Recommendation

Real-time Personalized Patient Care. 96x Faster on Xilinx.

In this test, the Alveo U55C card performed 96x faster than a CPU running the TigerGraph Cosine Similarity recommendation engine across millions of patient records to deliver results in milliseconds.


Fraud Detection

Real-Time Fraud Detection. 45X Faster on Xilinx.

With TigerGraph’s Graph analytics database running on the Alveo U55C card, the Louvain clustering algorithm detected fraudulent attempts across hundreds of bank accounts 45x faster.

Finite Element Method Acceleration


When you’re running life-saving simulations you don’t have time to wait weeks for answers. You need them in real-time.


Dimensions of matrix - 12 million
Time in sec: JPCG solver equation runtime
CPU: Intel Xeon E5-2665

Life Saving Simulations. 5x Faster.

LS-DYNA from ANSYS is a general-purpose finite element program capable of simulating complex real-world problems. LS-DYNA allows designers and engineers the ability to create simulations with an infinite amount of complexity.

In this this test, LS-DYNA tapped into the Alveo U55C cards’ scale-out fabric and non-hierarchical memory structure to obtain answers 5x faster than alternate solutions.

Real-Time Signal Processing Acceleration


The Alveo U55C card is ideally suited for processing terabytes of sensor data in real time, via distributed processing across hundreds of Alveo accelerator cards.


Radio Astronomy

Cataloging the origins of the universe requires terabits of sensor data to be processed in real time.

The Commonwealth Scientific and Industrial Research Organization’s (CSIRO) Square Kilometer Array (SKA) - the world’s largest radio astronomy antenna array – depends on Alveo U55C cards to perform end-to-end signal packet processing on incoming data at 15Tbps for real-time data flow.

The Alveo card-based cluster allows CSIRO to tackle the massive compute task of aggregating, filtering, preparing and processing data from 131,000 antennae in real time. The 460GBs of HBM2 bandwidth across the signal processing cluster is served by 420 Alveo U55C cards fully networked together across P4-enabled 100Gbs switches.


Up to 50x Lower in Price, Area & Power Efficiency vs GPU Benchmark

The explosion of sensors at the Edge has accelerated the need to process data in real-time.

Commodity GPUs running streaming sensor data clusters simply can’t keep up with the price, performance and power that Alveo U55C cards deliver.
