01Summary
It supports parallel scaling across GPU clusters and integrates with AI agents for automated pipeline orchestration. Visibility outputs serve downstream calibration and imaging workflows.
Summarised from the original article by an open-source model, then checked automatically: every number and English name must appear in the source. The original article is authoritative.
02Key points
- xBeam reduces 10 TB correlation time from 31,992 to 70 seconds (460x speedup).
- Supports parallel scaling via --devices or --shard-count/--shard-index across nodes.
- Processes VDIF frames with delay, fringe correction, FFT, and cross-multiplication to generate visibilities.
- AI agents parse metadata, generate job specs, launch and monitor GPU-based correlation.
