While DiLoCo communicates infrequently, its outer synchronization remains bandwidth-heavy and brittle to stragglers and transient failures. We relax exact synchronization to approximate synchronization via mixing/gossip, which degrades gracefully under delays and communication failures. This allows us to factorize DiLoCo synchronization into a non-blocking mixing step that overlaps computation with no staleness, and a blocking mixing step that tightens wo","authors_text":"Alexander Long, Chamin Hewa Koneputugodage, Gil Avraham, Hadi Mohaghegh Dolatabadi, James Snewin, Karol Pajak, Sameera Ramasinghe, Shamane Siriwardhana, Thalaiyasingam Ajanthan, Violetta Shevchenko","cross_cats":["cs.DC"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2026-06-22T02:15:13Z","title":"Factored Gossip DiLoCo: Reducing Blocking Communication in DiLoCo"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.22768","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:524104cb8c4f34954f7d1b022e8d4620fc051fbb6edafb48bf2e0f3b8d966744","target":"record","created_at":"2026-06-23T02:13:54Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"0e7583f29f03d65997f69aa1ddd08dc1d7355551fee66feb683e5622c2441234","cross_cats_sorted":["cs.DC"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2026-06-22T02:15:13Z","title_canon_sha256":"d315880a3ee4ff044fb82d664e500456ed9ab3b1273c7f7d59dfab98076a3766"},"schema_version":"1.0","source":{"id":"2606.22768","kind":"arxiv","version":1}},"canonical_sha256":"4184f05ecadcf969450c0116e6add33a54cdee2d0752d241fc953aae147beabe","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4184f05ecadcf969450c0116e6add33a54cdee2d0752d241fc953aae147beabe","first_computed_at":"2026-06-23T02:13:54.037927Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-23T02:13:54.037927Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"p5vOL6TDvhGId2ugB38cY33y3Ok3XlV44KnJ2kHFX+4vs95WZZmDnJq0E77iAbYFroSMCivbqafi6J7BNTkSCg==","signature_status":"signed_v1","signed_at":"2026-06-23T02:13:54.038351Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.22768","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:524104cb8c4f34954f7d1b022e8d4620fc051fbb6edafb48bf2e0f3b8d966744","sha256:1a08f5b5fc8cad235d2544000faa4d1cc9a64fd187b0b7b1c33c6bea077ce752"],"state_sha256":"3443e23e763e8f8bd3306fd1775c7b3fbb18d21f18cf909dfd1ac7a66f8b53e5"}
