The GIPSY coordinate system is implemented in terms of a collection of mostly FITS-compatible GDS descriptor items. ... The axis name is uniquely related to the physical coordinates of the pixels along the axis. ... For this position the physical coordinate is precisely defined in CRVAL i , and therefore we call this position the projection centre. ... The GIPSY coordinate system also recognizes secondary axis descriptors, which relate grid positions to a different type of physical units. ...

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 . ...
