International links of 100 Gbps or higher are frequently considered the primary enabler. While necessary, this network-centric view is incomplete. It equates provisioned link speeds with practical, sustainable data movement capabilities. It is a common observation that lower-than-desired data rates manifest even on 10 Gbps links, with higher-speed networks only amplifying their visibility. We investigate six paradigms -- from network latency and TCP congestion control to host-side factors such as CPU performa"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"principal bottlenecks often reside outside the network core, and that a holistic hardware-software co-design enables consistent, predictable performance for moving data at scale and speed","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"That the six investigated paradigms capture the dominant constraints across heterogeneous production environments and that the Drainage Basin Pattern model provides a sufficiently complete framework for identifying them","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Bottlenecks in large-scale data movement usually sit outside the network core, and a new Drainage Basin Pattern model helps identify them for better hardware-software co-design.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Bottlenecks in high-speed data movement often lie outside the network core in host-side factors.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"0a2157501fb8c2c8aab926b9c5fc241c7e04243f4ba80170c14caa52590a1a7b"},"source":{"id":"2512.15028","kind":"arxiv","version":7},"verdict":{"id":"13f9e253-1559-4bb8-99fa-3b06446d59ef","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-16T22:17:38.890694Z","strongest_claim":"principal bottlenecks often reside outside the network core, and that a holistic hardware-software co-design enables consistent, predictable performance for moving data at scale and speed","one_line_summary":"Bottlenecks in large-scale data movement usually sit outside the network core, and a new Drainage Basin Pattern model helps identify them for better hardware-software co-design.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"That the six investigated paradigms capture the dominant constraints across heterogeneous production environments and that the Drainage Basin Pattern model provides a sufficiently complete framework for identifying them","pith_extraction_headline":"Bottlenecks in high-speed data movement often lie outside the network core in host-side factors."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2512.15028/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
