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 Rockport Networks, 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
I recall reading this paper a couple of years ago. The interesting point at the end was (paraphrased) ‘hey: no hardware exists that supports our idea’. This hasn’t changed yet, has it?
I recall reading about this a couple of years back after someone had a talk with me about it at an SC. (cool Tshirt from the hpc lab in NO too) They problem was (paraphrased) ‘no hardware exists that supports this idea’. Has this changed?
