  • princeton university — (body, education)   Chartered in 1746 as the College of New Jersey, Princeton was British North America's fourth college. First located in Elizabeth, then in Newark, the College moved to Princeton in 1756. The College was housed in Nassau Hall, newly built on land donated by Nathaniel and Rebeckah FitzRandolph. Nassau Hall contained the entire College for nearly half a century. The College was officially renamed Princeton University in 1896; five years later in 1900 the Graduate School was established. Fully coeducational since 1969, Princeton now enrolls approximately 6,400 students (4,535 undergraduates and 1,866 graduate students). The ratio of full-time students to faculty members (in full-time equivalents) is eight to one. Today Princeton's main campus in Princeton Borough and Princeton Township consists of more than 5.5 million square feet of space in 160 buildings on 600 acres. The University's James Forrestal Campus in Plainsboro consists of one million square feet of space in four complexes on 340 acres. As Mercer County's largest private employer and one of the largest in the Mercer/Middlesex/Somerset County region, with approximately 4,830 permanent employees - including more than 1,000 faculty members - the University plays a major role in the educational, cultural, and economic life of the region.
  • priority inheritance — (parallel)   A technique for avoiding priority inversion by temporarily raising the prioriry of all processes that want to access a shared resource to the highest priority level of any of them. Priority inversion occurs where a low priority process, L is holding a resource required by a high priority process, H, but L is not running because a medium priority process, M is running. Under priority inheritance, L temporarily inherits H's priority, allowing L to run and release the resource H is waiting for. For example, an ambulance (H) is stuck behind a lorry (L) waiting at a junction (the shared resource) for a gap in a line of cars (M) using the junction. Applying priority inheritance, the cars give way to the lorry as they would to the ambulance, thus allowing the lorry and then the ambulance to use the junction.
