Grimshaw anticipated that gigabit networks will make possible the realization of very large nationwide virtual computers comprised of a variety of geographically distributed high-performance machines and workstations. To realize the potential of the physical infrastructure , software must be developed that is easy to use , supports large degrees of parallelism in applications code , and manages the complexity of the underlying physical system for the user. Grimshaw’s early research projects include Mentat and ELFS. Mentat was an early object-oriented parallel processing system designed to simplify the task of writing parallel programs. ELFS (Extensible File Systems) addresses the I\/O crisis brought on by parallel computers. These projects laid the foundation for the creation of Legion<\/a> , a collaborative project to realize the potential of the NII by constructing a very large virtual computer that spans the globe. Legion addresses issues such as parallelism , fault-tolerance , security , autonomy , heterogeneity , resource management , and access transparency in a multi-language environment. The Legion project helped set the standards for current Grid Computing research , and has also formed the technological basis of Avaki Corporation (now merged with Sybase<\/a>)<\/p>\n","protected":false},"featured_media":1734243,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false,"_links_to":"","_links_to_target":""},"otheraff":[],"phd-degree":[],"primary":[2358],"research-discipline":[],"research-opportunity":[],"training-grant":[],"class_list":["post-1730683","faculty-listing","type-faculty-listing","status-publish","has-post-thumbnail","hentry","primary-computer-science"],"acf":[],"yoast_head":"\nGrimshaw, Andrew - Research Faculty Directory<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/med.virginia.edu\/faculty\/faculty-listing\/ag8t\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Grimshaw, Andrew - Research Faculty Directory\" \/>\n<meta property=\"og:description\" content=\"Grimshaw anticipated that gigabit networks will make possible the realization of very large nationwide virtual computers comprised of a variety of geographically distributed high-performance machines and workstations.
