The IoT applications generally take the form of directed acyclic graphs (DAGs), where vertices represent interdependent functions and edges represent data streams. The status quo of minimizing the makespan of the DAG motivates the study on optimal function placement. However, current approaches lose sight of proactively mapping the data streams to the physical links between the heterogenous edge servers, which could affect the makespan of DAGs significantly. To solve this problem, we study both function placement and stream mapping with data splitting simultaneously, and propose the algorithm DPE (Dynamic Programming-based Embedding). DPE is theoretically verified to achieve the global optimality of the embedding problem. The complexity analysis is also provided. Extensive experiments on Alibaba cluster trace dataset show that DPE significantly outperforms two state-of-the-art joint function placement and task scheduling algorithms in makespan by 43.19% and 40.71%, respectively.","url_abs":"https://arxiv.org/abs/2012.04158v1","url_pdf":"https://arxiv.org/pdf/2012.04158v1.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":"placement-is-not-enough-embedding-with","repo_url":"https://github.com/hliangzhao/Dependent-Function-Embedding","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
