In order to determine performance of program normal form of analysis of program is to just calculate total amount of CPU time needed to execute different part of program it implies procedures. But in case of a parallel algorithm executing on parallel computer performance metric is dependent on numerous factors like memory hierarchy, inter-process communication. There are a lot of tools like INCAS, JEWEL and ANALYZER to provide profiles of utilization of a variety of resources like CPU utilisation, Cache Performance and Disk Operations etc. These tools even give information about different types of overheads. Now let's consider different types of performance analysis tools.
(a) A current of 15A fl ows through a load having a resistance of 4Ω . Determine the power dissipated in the load. (b) A wattmeter, whose current coil has a resistance of
Sketch a graph showing the relationship among the magnetic field around a straight, current-carrying wire, and the distance from the wire. This is a graph of y = 1/x.
Beauty criterion (Dirac) The idea that the more aesthetically pleasant a theory is, the better it is. Of course this criterion does not stand up to the real test whether or no
High resistive materials: The materials which have their resistivity 10 -8 to 10 -6 ohm-m come under this category. These materials are used for making resistance elements fo

The current is an RL circuit drops from 1.1 A to 13 mA in the first second following removal of the battery from the circuit. If L is 12H, find the resistance R in the circuit.
A multimode, step-profile fibre has a core radius of 50 microns, a core index of 1.52 and a cladding index of 1.50. (a) If the fibre end-face is excited by a source with a wave
The average distance of an electron in an atom from its nucleus is of the order of: (1) 10 6 m (2) 10 -6 m (3) 10 -10 m (4)10 -15 m Ans: (3) 10 -10 m
A Plane polarized light is incident on a piece of quartz cut parallel to its axis. Evaluate the least thickness for which ordinary ray and extraordinary ray combine
How to identify a hard-boiled egg Secure a fresh egg and a hard-boiled egg. Give every of them a spinning motion in a soup dish or a plate. View that the hard-boiled one spins
