How to pronounce fsdp

fsdp is most commonly pronounced "eff ess dee pee" (/ˌɛf ˌɛs ˌdiː ˈpiː/). This is the widely-used reading among engineers, though edge cases exist.

Fully Sharded Data Parallel — PyTorch's ZeRO-style multi-GPU training strategy that shards parameters, gradients, and optimizer states across ranks. Initialism, spelled out letter-by-letter: EFF-ESS-DEE-PEE (no widely-used word pronunciation). Central to multi-GPU/LLM training docs since 2022; FSDP2 is the current rewrite.

Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will.
