Approximate Computing leverages the inherent error tolerance of many applications to trade computational accuracy for gains in performance and energy efficiency. Unlike prior OpenMP\u2010based approximation proposals, which typically focus on a single technique, our constructor provides a unified and portable interface that integrates multiple software approximation strategies. The proposed construct provides native support for software Approximate Computing strategies, including\n                    <jats:italic>task dropping<\/jats:italic>\n                    ,\n                    <jats:italic>loop perforation<\/jats:italic>\n                    ,\n                    <jats:italic>floating\u2010point relaxation<\/jats:italic>\n                    , and\n                    <jats:italic>memoization<\/jats:italic>\n                    , enabling developers to selectively apply these techniques with minimal code disruption. The experimental evaluation across a set of representative benchmark applications reveals performance improvements of up to 1272.90%, with a degradation of 83.3% accuracy and energy savings reaching up to 99.34% in specific configurations. These results underscore the viability of Approximate Computing alongside parallel programming models and open the door for further exploration of compiler and runtime support for controlled inaccuracy in high\u2010performance computing.\n                  <\/jats:p>","DOI":"10.1002\/cpe.70584","type":"journal-article","created":{"date-parts":[[2026,2,10]],"date-time":"2026-02-10T03:13:36Z","timestamp":1770693216000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Multithread Approximation: An\n                    <scp>OpenMP<\/scp>\n                    Constructor"],"prefix":"10.1002","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-6383-8691","authenticated-orcid":false,"given":"Jo\u00e3o Briganti","family":"de Oliveira","sequence":"first","affiliation":[{"name":"Universidade Tecnol\u00f3gica Federal do Paran\u00e1 (UTFPR)  Campo Mour\u00e3o Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7020-6723","authenticated-orcid":false,"given":"Rog\u00e9rio","family":"Aparecido Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Universidade Tecnol\u00f3gica Federal do Paran\u00e1 (UTFPR)  Campo Mour\u00e3o Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6036-4031","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Fabr\u00edcio Filho","sequence":"additional","affiliation":[{"name":"Universidade Tecnol\u00f3gica Federal do Paran\u00e1 (UTFPR)  Campo Mour\u00e3o Paran\u00e1 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,2,9]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/3282307"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/2893356"},{"key":"e_1_2_14_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2024.3467375"},{"key":"e_1_2_14_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/MDAT.2015.2505723"},{"key":"e_1_2_14_6_1","doi-asserted-by":"publisher","DOI":"10.1145\/3716845"},{"key":"e_1_2_14_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/3711683"},{"key":"e_1_2_14_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11390\u2010023\u20102537\u2010y"},{"key":"e_1_2_14_9_1","doi-asserted-by":"publisher","DOI":"10.1145\/3394885.3431551"},{"key":"e_1_2_14_10_1","doi-asserted-by":"publisher","DOI":"10.1109\/SBAC-PAD53543.2021.00030"},{"key":"e_1_2_14_11_1","doi-asserted-by":"publisher","DOI":"10.1109\/HICSS.2016.710"},{"key":"e_1_2_14_12_1","doi-asserted-by":"publisher","DOI":"10.1109\/ICCMC51019.2021.9418401"},{"key":"e_1_2_14_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/pro.767"},{"key":"e_1_2_14_14_1","doi-asserted-by":"publisher","DOI":"10.1145\/2742482"},{"key":"e_1_2_14_15_1","doi-asserted-by":"publisher","DOI":"10.1137\/0719025"},{"key":"e_1_2_14_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cam.2005.10.013"},{"key":"e_1_2_14_17_1","doi-asserted-by":"publisher","DOI":"10.6028\/jres.049.006"},{"key":"e_1_2_14_18_1","doi-asserted-by":"publisher","DOI":"10.1145\/3458817.3476216"},{"key":"e_1_2_14_19_1","volume-title":"SC: International Conference for High Performance Computing, Networking, Storage and Analysis","author":"Fink Z.","year":"2023"},{"issue":"2","key":"e_1_2_14_20_1","first-page":"1","article-title":"Accept: A Programmer\u2010Guided Compiler Framework for Practical Approximate Computing","volume":"1","author":"Sampson A.","year":"2015","journal-title":"University of Washington Technical Report UW\u2010CSE\u201015\u201001"},{"key":"e_1_2_14_21_1","unstructured":"LLVM \u201cLLVM\/OpenMP 22.0.0git Documentation \u201d2025 https:\/\/openmp.llvm.org\/."},{"key":"e_1_2_14_22_1","first-page":"49","volume-title":"Anais da XV Escola Regional de Alto Desempenho de S\u00e3o Paulo","author":"Oliveira J.","year":"2024"},{"key":"e_1_2_14_23_1","doi-asserted-by":"publisher","DOI":"10.5753\/sscad.2024.244776"},{"key":"e_1_2_14_24_1","volume-title":"The OpenMP Common Core","author":"Mattson T.
