Limited CPU resources have traditionally forced VEs to be simplified for real-time performance. Multi-core processors greatly increase the computational capacity of computers and are quickly becoming standard. However, developing non-application specific methods to fully utilize all available CPU cores for processing VEs is difficult. The paper describes a pipeline VE architecture designed for multi-core CPU systems. The architecture enables development of VEs that leverage the computational resources of all CPU cores for VE simulation. A VE's workload is dynamically distributed across the available CPU cores. A VE can be developed once and scale efficiently with the number of cores. The described pipeline architecture makes it possible to develop complex physically-based VEs for medical simulations. Initial results for a craniotomy simulator being developed have shown super-linear and near-linear speedups when tested with up to four cores.<\/jats:p>","DOI":"10.3233\/978-1-58603-964-6-10","type":"book-chapter","created":{"date-parts":[[2025,2,22]],"date-time":"2025-02-22T23:19:26Z","timestamp":1740266366000},"source":"Crossref","is-referenced-by-count":0,"title":["A Multi-core CPU Pipeline Architecture for Virtual Environments"],"prefix":"10.3233","author":[{"family":"Acosta Eric","sequence":"additional","affiliation":[]},{"family":"Liu Alan","sequence":"additional","affiliation":[]},{"family":"Sieck Jennifer","sequence":"additional","affiliation":[]},{"family":"Muniz Gilbert","sequence":"additional","affiliation":[]},{"family":"Bowyer Mark","sequence":"additional","affiliation":[]},{"family":"Armonda Rocco","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Medicine Meets Virtual Reality 17"],"original-title":[],"deposited":{"date-parts":[[2025,2,22]],"date-time":"2025-02-22T23:41:06Z","timestamp":1740267666000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0926-9630&volume=142&spage=10"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-58603-964-6-10","relation":{},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[2009]]}}}
