Running Low-Latency Analytical Workloads with GPU-Accelerated Presto on NVIDIA GB200 NVL72 | NVIDIA Technical Blog

This post details the performance improvements achieved by GPU-accelerated Presto on NVIDIA GB200 NVL72 systems, demonstrating up to 8x lower latency compared to CPU-based Presto clusters. It highlights the critical role of NVIDIA GPUDirect Storage (GDS) for high I/O throughput when paired with IBM Storage Scale, and optimizations in data transfer (increasing I/O task size, using more I/O threads) and communication (UcxExchange configuration). The post also showcases the impact of query rewrites, specifically for Q11, which reduced runtime from 50 seconds to 2 seconds by utilizing a GPU-based parquet writer for efficient result storage.
