This post covers measured PyTorch DDP scaling results on 8xV100 SXM2 and 8xA100 SXM4, using ResNet-152 and ViT-B/16 with fp16 and bf16, and explains what the numbers actually mean for system selection. https://theloginnode.com/posts/hpc-special-topics-01/ Mon, 16 Feb 2026 00:00:00 +0000 https://theloginnode.com/posts/hpc-special-topics-01/ Running rclone copy with default settings works, but it is usually much slower than it needs to be. This post covers how to configure Rclone for HPC workflows, benchmark real transfer speeds across cloud storage providers, and tune the parameters that actually affect throughput on a cluster network.
