Through a\nnovel perspective, we revisit and clarify a subtle but important technical\nissue present in a large fraction of the recent convergence rate proofs for\nasynchronous parallel optimization algorithms, and propose a simplification of\nthe recently introduced \"perturbed iterate\" framework that resolves it. We\nthereby prove that ASAGA can obtain a theoretical linear speedup on multi-core\nsystems even without sparsity assumptions. We present results of an\nimplementation on a 40-core architecture illustrating the practical speedup as\nwell as the hardware overhead.","url_abs":"http://arxiv.org/abs/1606.04809v3","url_pdf":"http://arxiv.org/pdf/1606.04809v3.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":"abstracts"},"code_links":[{"paper_slug":"asaga-asynchronous-parallel-saga","repo_url":"https://github.com/RemiLeblond/ASAGA","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":{"status":"ok"}}],"tasks":[],"methods":[{"method_slug":"saga","method_name":"SAGA"}],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1606.04809","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
