This paper contributes a new, lock-free, amortized constant-time memory reclamation scheme called \\emph{Stamp-it}, and compares it to five well-known, selectively efficient schemes from the literature, namely Lock-free Reference Counting, Hazard Pointers, Quiescent State-based Reclamation, Epoch-based Reclamation, and New Epoch-based Reclamation. An extensive, experimental evaluation with both new and commonly used benchmarks is provided, on four different shared-memory systems with hardware supported thread counts ranging from 48 to 512, showing Stamp-it to be competitive with and in many cases and aspects outperforming other schemes.","url_abs":"http://arxiv.org/abs/1712.06134v1","url_pdf":"http://arxiv.org/pdf/1712.06134v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"a-new-and-five-older-concurrent-memory","repo_url":"https://github.com/mpoeter/emr-benchmarks","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
