Scientists, increasingly fighting for valuable resources on conventional high-performance computing (HPC) facilities\u2014often with a limited customizable user environment\u2014are increasingly looking to hardware acceleration solutions. We describe here a heterogeneous CPU\/GPGPU\/FPGA desktop computing system (the \u201cChimera\u201d), built with commercial-off-the-shelf components. We show that this platform may be a viable alternative solution to many common computationally bound problems found in astronomy, however, not without significant challenges. The most significant bottleneck in pipelines involving real data is most likely to be the interconnect (in this case the PCI Express bus residing on the CPU motherboard). Finally, we speculate on the merits of our Chimera system on the entire landscape of parallel computing, through the analysis of representative problems from UC Berkeley\u2019s \u201cThirteen Dwarves.\u201d<\/jats:p>","DOI":"10.1155\/2012\/241439","type":"journal-article","created":{"date-parts":[[2012,3,22]],"date-time":"2012-03-22T11:09:40Z","timestamp":1332414580000},"page":"1-10","source":"Crossref","is-referenced-by-count":30,"title":["The \u201cChimera\u201d: An Off-The-Shelf CPU\/GPGPU\/FPGA Hybrid Computing Platform"],"prefix":"10.1155","volume":"2012","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0256-7938","authenticated-orcid":true,"given":"Ra","family":"Inta","sequence":"first","affiliation":[{"name":"The Centre for Gravitational Physics, Department of Quantum Science, The Australian National University, Canberra, ACT 0200, Australia"}]},{"given":"David J.","family":"Bowman","sequence":"additional","affiliation":[{"name":"The Centre for Gravitational Physics, Department of Quantum Science, The Australian National University, Canberra, ACT 0200, Australia"}]},{"given":"Susan M.","family":"Scott","sequence":"additional","affiliation":[{"name":"The Centre for Gravitational Physics, Department of Quantum Science, The Australian National University, Canberra, ACT 0200, Australia"}]}],"member":"311","reference":[{"issue":"1","key":"1","doi-asserted-by":"crossref","first-page":"46","DOI":"10.1086\/306308","volume":"507","year":"1998","journal-title":"Astrophysical Journal"},{"issue":"1","key":"2","first-page":"L1","volume":"396","year":"1992","journal-title":"Astrophysical Journal"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1086\/377226"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1126\/science.1195253"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1126\/science.1200970"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1088\/0264-9381\/27\/13\/135009"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2966.2010.17257.x"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1007\/s10686-011-9217-6"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1051\/0004-6361:20065415"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1109\/MCSE.2009.11"},{"key":"40","year":"2008"},{"key":"43","year":"1997"},{"key":"44","doi-asserted-by":"publisher","DOI":"10.1109\/5.284733"},{"key":"49","doi-asserted-by":"publisher","DOI":"10.1155\/2010\/357978"},{"key":"50","doi-asserted-by":"publisher","DOI":"10.1002\/cpa.20124"},{"key":"51","year":"2008"},{"key":"54","year":"2004"},{"key":"56","doi-asserted-by":"publisher","DOI":"10.1038\/324446a0"}],"container-title":["International Journal of Reconfigurable Computing"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijrc\/2012\/241439.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijrc\/2012\/241439.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijrc\/2012\/241439.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,20]],"date-time":"2017-06-20T11:55:36Z","timestamp":1497959736000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/ijrc\/2012\/241439\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":18,"alternative-id":["241439","241439"],"URL":"https:\/\/doi.org\/10.1155\/2012\/241439","relation":{},"ISSN":["1687-7195","1687-7209"],"issn-type":[{"value":"1687-7195","type":"print"},{"value":"1687-7209","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012]]}}}
