This is to our knowledge the first implementation of a parallel search structure that is work-optimal with respect to the finger bound and yet has very good parallelism (within a factor of O( (log p)^2 ) of optimal). We utilize an extended implicit batching framework that transparently facilitates the use of FS by any parallel program P that is modelled by a dynamically generated DAG D where each node is either a unit-time instr","authors_text":"Seth Gilbert, Wei Quan Lim","cross_cats":["cs.DC"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2019-08-07T17:35:50Z","title":"Parallel Finger Search Structures"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.02741","kind":"arxiv","version":4},"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":"sha256:3619a1e14bfa00e7e2085c309aa6b3ed0d4ffeed0d2cab5c415654528219851c","target":"record","created_at":"2026-07-05T00:11:15Z","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":"e1e9015dd466505562f12b190cdb3b8c7b77d6b240ed76918a3035306c057fe3","cross_cats_sorted":["cs.DC"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2019-08-07T17:35:50Z","title_canon_sha256":"f0fe6cbcd5fb743efdf472536386e385ce1bfddc637b331f34c8c40010f48240"},"schema_version":"1.0","source":{"id":"1908.02741","kind":"arxiv","version":4}},"canonical_sha256":"9c1e2735ec5d3e51ad4254be44cf739cd1e5abcdc48a59be42516f9d6aab13dc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9c1e2735ec5d3e51ad4254be44cf739cd1e5abcdc48a59be42516f9d6aab13dc","first_computed_at":"2026-07-05T00:11:15.209471Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:11:15.209471Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Lzocb2v65LV3JjowjnfDX8G01o9/WX35vdEFXnBOjF0F0DaJSfEMil+hjS3RgJ1hWkfouC1qFQtDU23Bk/4ZCA==","signature_status":"signed_v1","signed_at":"2026-07-05T00:11:15.209918Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.02741","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3619a1e14bfa00e7e2085c309aa6b3ed0d4ffeed0d2cab5c415654528219851c","sha256:0f7f11b182915a5cfaa1b1bcd43d774b06729b9ae8e51387b4b7e330319f95a9"],"state_sha256":"231dadabdecf34511bfa3a036ee1a769ab9fda068ceaa8e9702b8cfac2f6c2f5"}
