Speeding Up AI: Bringing Google Colossus to PyTorch via GCSFS and Rapid Bucket

Google Cloud announces Rapid Bucket, integrating Colossus storage with PyTorch for accelerated AI/ML training.

• •Rapid Bucket uses gRPC bidirectional streaming instead of REST APIs, delivering 15+ TiB/s throughput, <1ms latency, and 20M+ QPS.
• •fsspec and gcsfs integration enables PyTorch users to access performance gains through simple fsspec.open() calls without code modifications.
• •Benchmarks show 23% faster training time on 16 A4 GPUs, with 4.8x read performance and 2.8x write performance improvements.
• •Direct connectivity and zonal co-location eliminate cross-zone latency and reduce per-operation overhead.
