1.7 [15] < §1.6> compilers can have a profound impact on the performance of an application. assume that for a program, compiler a results in a dynamic instruction count of 1.0e9 and has an execution time of 1.1 s, while compiler b results in a dynamic instruction count of 1.2e9 and an execution time of 1.5 s.(a) find the average cpi for each program given that the processor has a clock cycletime of 1 ns.(b) assume the compiled programs run on two different processors. if the executiontimes on the two processors are the same, how much faster is the clock of theprocessor running compiler a’s code versus the clock of the processor runningcompiler b’s code?

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned
