Pump Up the Volume: Processing Large Data on GPUs with Fast Interconnects

Clemens Lutz from DFKI published a Blogpost to the SIGMOD Paper 'Pump Up the Volume: Processing Large Data on GPUs with Fast Interconnects' for the ACM SIGMOD/PODS International Conference on Management of Data, Portland, USA in 2020. The paper is written by Clemens Lutz, Sebastian Breß, Steffen Zeuch, Tilmann Rabl, Volker Markl.

Sneak peak:

Recently, multiple GPU vendors have released or announced GPUs with interconnects that provide unprecedented connectivity to the CPU and main-memory. NVLink 2.0 by Nvidia [2], Infinity Fabric by AMD [3], and Compute Express Link by Intel [4, 5] are a new class of fast GPU interconnects. These promise bandwidth up to 150 GB/s, and offer a new solution to an age-old problem described in database literature called the data transfer bottleneck.

In our recent publication that was accepted at the ACM SIGMOD conference [1], we investigate the benefits and challenges of fast interconnects for processing data-intensive applications on GPUs. In this post, we will cover what fast interconnects are capable of today, and why they might change the game for GPU-enabled data processing.
