The widely used GNU OpenMP implementation of the popular OpenMP parallel programming model incurs high overhead for fine-grained, short-running tasks due to time spent on runtime synchronization. In this work, we introduce and analyze three key advances that collectively achieve significant performance gains. First, we introduce XQueue, a lock-less concurrent queue implementation to replace GNU's priority task queue and remove the global task lock. Second, we develop a scalable, efficient, and hybrid loc","authors_text":"Haochen Pan, Ian Foster, Ioan Raicu, Kyle Chard, Maxime Gonthier, Poornima Nookala, Wenyi Wang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.DC","submitted_at":"2025-02-07T19:53:29Z","title":"Optimizing Fine-Grained Parallelism Through Dynamic Load Balancing on Multi-Socket Many-Core Systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.05293","kind":"arxiv","version":2},"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:ba9741280fa8d9f3115e855ce23e74e0ed2eede4f58857b6c78e6d64134c8597","target":"record","created_at":"2026-07-05T10:34:42Z","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":"2ed2e09d4d38e1de8539d1de8070809e3ba0aae7d1c95693dffd3051a4a64370","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.DC","submitted_at":"2025-02-07T19:53:29Z","title_canon_sha256":"7c6cc8b4ba63f2db37927ea694fe314fe2cd5b9786c9215d787c7cd2041f7792"},"schema_version":"1.0","source":{"id":"2502.05293","kind":"arxiv","version":2}},"canonical_sha256":"137fd0ec35fb20d89e020dc72da083bd2a685a798b102497c39ee299e7d6e007","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"137fd0ec35fb20d89e020dc72da083bd2a685a798b102497c39ee299e7d6e007","first_computed_at":"2026-07-05T10:34:42.430833Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:34:42.430833Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"m5EGBfZ9YU4KYGgafMdAWMUQpzXawT0ee5MXy7aznTfQQC9qs5lruv5lFEO/oaeG3945WjErguR2zDXngHoeBA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:34:42.431453Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.05293","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ba9741280fa8d9f3115e855ce23e74e0ed2eede4f58857b6c78e6d64134c8597","sha256:72debb44a60e56998fb4ae169295bcf8ec4ca8c3f509a5aec608d8b665af390d"],"state_sha256":"e3d6f239fab3c0e56e3dd3acbd21afcc340a71beecf487e6ce00a84cedf0ce89"}
