On the Performance of a Fast Optically Switched Network for Machine-Learning Accelerator Clusters

M.P.G. Rombouts and N. Calabretta

Not Accessible

Your library or personal account may give you access

Abstract

We investigate the viability of optically switched network for ML accelerator clusters and compare it to a leaf-spine network with 256/1024 GPUs. Results show almost ideal throughput, sub-µs latency and zero packet-loss for ¡0.6 traffic-load.
