The HyperNews Linux KHG Discussion Pages . ... Keywords: scheduler overhead . ... From: Jasleen Kaur < jks@cs.utexas.edu > . Hi, I am implementing a different scheduling policy in the scheduler of Linux 2.0.0. I need to measure the time taken for choosing the next task to be scheduled, i.e., the actual time spent in the schedule() function, without the actual context switch having taken place. Since I clear interrupts in schedule(), how do I measure the time? ... Thanks, Jasleen Kaur . ...

Authors: V.A. Marsakov , T.V. Borkova , . ... It is shown that general populations of globular clusters and metal-poor field stars are components at least of three subsystems occupying different volumes in the Galaxy. The thick disk and proto-disk subsystems are genetically associated with the Galaxy. ... It is argued that heavy-element enrichment and the collapse of the proto-galactic medium occurred mainly in the period between the formation of the proto-disk halo and thick disk subsystems. ...
