More specifically, we parallelize using a Vertex-Centric (VC) computational model on a modern SIMD powered multicore architecture. We design a new VC-PLL algorithm that resolves the apparent mismatch between the inherent sequential dependence of the PLL algorithm and the Vertex- Centric (VC) computing model. Furthermore, we introduce a novel batch execution model for VC computation and the BVC-PLL algorithm to reduce the com","authors_text":"Bin Ren, Feodor Dragan, Gagan Agrawal, Ruoming Jin, Wendell Wu, Zhen Peng","cross_cats":["cs.DC"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DB","submitted_at":"2019-06-28T02:19:19Z","title":"Pruned Landmark Labeling Meets Vertex Centric Computation: A Surprisingly Happy Marriage!"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1906.12018","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:be6d6648694cf6cbf57f3115cd6833df91b0046e7f4400c44cc873af0cb46eed","target":"record","created_at":"2026-05-17T23:41:59Z","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":"f824b594070f4b177eb6c7ebd598cb71d461a48758a4acefaea78264e18dd39d","cross_cats_sorted":["cs.DC"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DB","submitted_at":"2019-06-28T02:19:19Z","title_canon_sha256":"dfe8933b96c7ef6dd0efcd555d1ef2809fbac28dc2199e4ef3e101f881460985"},"schema_version":"1.0","source":{"id":"1906.12018","kind":"arxiv","version":1}},"canonical_sha256":"719a4efc6bb29e5d4596dad98194dfd7a29674fe37624f1eec43bbf50aeb9d62","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"719a4efc6bb29e5d4596dad98194dfd7a29674fe37624f1eec43bbf50aeb9d62","first_computed_at":"2026-05-17T23:41:59.514765Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:41:59.514765Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fdeAipjhLXkS7HaARug05Q7IPz7AaLRegG2VdX6W9UpMtK+o82gwwQAP4+HQ53iZ7UV6ArKX3dsd0ELPng1LDw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:41:59.515382Z","signed_message":"canonical_sha256_bytes"},"source_id":"1906.12018","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:be6d6648694cf6cbf57f3115cd6833df91b0046e7f4400c44cc873af0cb46eed","sha256:7a8abaa03ce21019892db9fffe92e69cf8c0535ab2eb0e61d56a1f2a0c8c47ef"],"state_sha256":"eb0420e9fbf45b511a89031b9d29b10933b85d47b400092081d7cb20f9736359"}
