###### WHITEPAPER

# It's time to resolve the root cause of congestion

Today, every high-performance computing (HPC) workload running globally faces the same crippling issue: Congestion in the network.

Congestion can delay workload completion times for crucial scientific and enterprise workloads, making HPC systems unpredictable and leaving high-cost cluster resources waiting for delayed data to arrive. Despite various brute-force attempts to resolve the congestion issue, the problem has persisted. Until now.

###### In this paper, Matthew Williams, CTO at Cerio, explains how recent innovations in networking technologies have led to a new network architecture that targets the root causes of HPC network congestion, specifically:

- Why today's network architectures are not a sustainable approach to HPC workloads
- How HPC workload congestion and latency issues are directly tied to the network architecture
- Why a direct interconnect network architecture minimizes congestion and tail latency
