In this exercise, we examine the effect of the interconnection network topology on the clock cycles per instruction (CPI) of programs running on a 64-processor distributed-memory multiprocessor. The processor clock rate is 3. 3 GHz and the base CPI of an application with all references hitting in the cache is 0. 5. Assume that 0. 2% of the instructions involve a remote communication reference. The cost of a remote communication reference is (100 + 10h) ns, where h is the number of communication network hops that a remote reference has to make to the remote processor memory and back. Assume that all communication links are bidirectional.


a. Calculate the worst-case remote communication cost when the 64 processors are arranged as a ring, as an 8x8 processor grid, or as a hypercube. (Hint: The longest communication path on a 2n hypercube has n links. )


b. Compare the base CPI of the application with no remote communication to the CPI achieved with each of the three topologies in part (a).


c. How much faster is the application with no remote communication compared to its performance with remote communication on each of the three topologies in part (a)

Answer:

torque to raise the load = 16.411 Nm

torque to lower the load = 8.40 Nm

overall efficiency = 0.24

Explanation:

Given:

max load on vertical direction of the screw = Force = F = 5kN

frictional  diameter of the collar = 45 mm

Diameter = 25 mm

length of pitch = 5 mm

coefficient of friction for thread µ  = 0.09

coefficient of friction for collar µ\(_{c}\) = 0.06

To find:

torque to "raise" the load

torque to and "lower"

overall efficiency

Solution:

Compute torque to raise the load:

\(T_{R} = \frac{ Fd_{m}}{2} (\frac{L+(\pi ud_{m}) }{\pi d_{m}-uL }) +\frac{Fu_{c} d_{c} }{2}\)

where

\(T_{R}\) is the torque

F is the load

\(d_{m}\) is diameter of thread

\(d_{c}\) is diameter of collar

L is the thread pitch distance

µ is coefficient of friction for thread

µ\(_{c}\)  is coefficient of friction for collar

Putting the values in above formula:

\(T_{R}\) = 5(25) / 2 [5+ (π(0.09)(25) / π(25)-0.09(5)] + 5(0.06)(45) / 2

    = 125/2 [5 + (3.14)(0.09)(25)/ 3.14(25)-0.45] + 13.5/2

    = 62.5 [(5 + 7.065) / 78.5 - 0.45] + 6.75

    = 62.5 [12.065 / 78.05 ] + 6.75

    = 62.5 (0.15458) + 6.75

    = 9.66125 + 6.75

    = 16.41125

\(T_{R}\) = 16.411 Nm

Compute torque to lower the load:

\(T_{L} = \frac{ Fd_{m}}{2} (\frac{(\pi ud_{m}) - L }{\pi d_{m}-uL }) +\frac{Fu_{c} d_{c} }{2}\)

     = 5(25) / 2 [ (π(0.09)(25) - L / π(25)-0.09(5) ] + 5(0.06)(45) / 2

     = 125/2 [ ((3.14)(0.09)(25) - 5) / 3.14(25)-0.45 ] + 13.5/2

     = 62.5 [ (7.065 - 5) / 78.5 - 0.45 ] + 6.75

    = 62.5 [ 2.065 / 78.05 ] + 6.75

     = 62.5 (0.026457) + 6.75

     = 1.6535625 + 6.75

     = 8.40 Nm

Since the torque required to lower the the load is positive indicating that an effort is applied to lower the load, Hence the thread is self locking.

Compute overall efficiency:

overall efficiency = F(L) / 2π \(T_{R}\)

                             = 5(5) / 2(3.14)( 16.411)

                             = 25/ 103.06108

overall efficiency = 0.24

Option C. The correct statement about the static pressure p₂ relative to p₁ and the velocity V₂ relative to V₁ along the streamline down the center of the pipe is p₂ > p₁ and V₂ < V₁.

When fluid flows without friction through a horizontal pipe and enters a section where the cross-sectional area is smaller, the static pressure at the smaller area decreases relative to the static pressure at the larger area, whereas the velocity increases. Therefore, the correct statement about the static pressure p₂ relative to p₁ and the velocity V₂ relative to V₁ along the streamline down the center of the pipe is p₂ > p₁ and V₂ < V₁.

This is because the mass flow rate is conserved across any cross-section of the pipe, and this leads to an increase in fluid speed as the cross-sectional area decreases (and vice versa). As a result, the fluid experiences an increase in velocity head and a decrease in pressure head as it moves from the larger area to the smaller area.

Therefore the correct option is C.

As the angle of the ramp is increased, the force parallel increases. Hence, option (a) can be considered as the correct answer.

When the angle of a ramp is increased, the force parallel to the ramp, also known as the parallel component of the gravitational force, does increase. This is because the component of gravity acting parallel to the ramp increases with the angle. However, it's important to note that the total gravitational force acting on an object remains constant regardless of the angle of the ramp.As the angle of the ramp increases, the force required to push or pull an object up the ramp against gravity increases. This is due to the increase in the vertical component of the gravitational force, which opposes the motion up the ramp. The parallel force required to overcome this increased vertical force also increases.

The Reynolds number is a dimensionless parameter used in fluid mechanics to predict flow patterns in different fluids. It can be calculated using the formula pVD/u.

The Reynolds number, represented by Re, is a dimensionless number used to predict the flow behavior of fluids. It is determined by the ratio of the inertial forces to the viscous forces in a fluid.

The equation for Reynolds number is Re = pVD/u, where p is the density of the fluid, V is the velocity of the fluid, D is the diameter of the pipe, and u is the dynamic viscosity of the fluid.

Given the flow velocity of 2 m/s and pipe diameter of 5 inches (0.127 m), we need to find the dynamic viscosity of ethyl alcohol and density to calculate the Reynolds number. At 20°C, the dynamic viscosity of ethyl alcohol is 1.2 x 10⁻³ Pa·s and the density is 789 kg/m³.

Therefore, the Reynolds number for ethyl alcohol flowing at 2 m/s through a 5-inch diameter pipe is:

Re = (789 kg/m³) x (2 m/s) x (0.127 m) / (1.2 x 10⁻³Pa·s) = 1.05 x 10⁶  

So, the Reynolds number for this flow is relatively high, indicating that the flow will be turbulent.

To calculate the shear stress on the pipe wall, we can use the Hagen-Poiseuille equation, which relates the shear stress to the velocity distribution in a pipe. The Hagen-Poiseuille equation is given by:

In this case, the velocity distribution is given as U(r) = 5 [1 - (r^2/16) × 10^6] m/s.To calculate the velocity gradient, we need to find dU/dr. Taking the derivative of U(r) with respect to r, we get:

dU/dr = (-10r/8) × 10^6 m/s

Now we need the dynamic viscosity of water at 20°C. The dynamic viscosity of water at 20°C is approximately 1.002 × 10^(-3) Pa·s or kg/(m·s).Plugging in the values into the Hagen-Poiseuille equation, we have:

τ = (1.002 × 10^(-3) Pa·s) * [(-10r/8) × 10^6 m/s]

Simplifying further:

τ = -0.1252 * r * 10^3 Pa

Therefore, the shear stress on the pipe wall is given by -0.1252 * r * 10^3 Pa, where r is the radial distance from the center of the pipe.Note that the negative sign indicates that the shear stress acts in the opposite direction to the flow direction. Also, the units are in Pascals (Pa).

Boosting the strain rate or decreasing the temperature has the effect of raising the flow stress and decreasing ductility. The less uniform elongation before necking begins is what causes the poorer ductility; however, significant plastic flow may still be seen within the necked region.

Note that the primary distinction between yield strength and tensile strength is that the former refers to the lowest stress at which a material would permanently deform, whilst the latter refers to the highest tension at which a material will withstand before failing.

Tech A and Tech B are correct

Explanation:

Given data:Pressure of the two flows, P = 200 kPaFlow rate of 1st flow, m₁ = 1 kg/sFlow rate of 2nd flow, m₂ = 2 kg/sTemperature of 1st flow, T₁ = 400 KTemperature of 2nd flow, T₂ = 290 KLet the exit temperature be T.

Energy balance equation at the insulated box can be given as:

m₁Cp₁T₁ + m₂Cp₂T₂ = (m₁ + m₂)Cp.T.

(Where Cp₁ and Cp₂ are the specific heats of the gases)Also, the mass flow rate should be conserved:m₁ + m₂ = m₃ (where m₃ is the mass flow rate of the exit flow).

Therefore, the specific heat of the exit flow can be expressed as:

Cp.T = (m₁Cp₁T₁ + m₂Cp₂T₂)/(m₁ + m₂)

Substituting the given values,

Cp.T = (1 x 1005 x 400 + 2 x 1005 x 290)/(1 + 2) = 324.33 J/kg

KAgain, applying energy balance equation,Q₃ - W₃ = 0 (where Q₃ is the heat transferred to the system and W₃ is the work done by the system)Since the process is adiabatic, Q₃ = 0Therefore, W₃ = 0Also, from the second law of thermodynamics, the rate of entropy generation can be expressed as:σ = m₃S.

(Where S is the entropy per unit mass of the exit flow)Now, the entropy balance equation can be given as:

(m₁S₁ + m₂S₂) = m₃S

Where S₁ and S₂ are the specific entropy of the gasesTherefore,

S = (m₁S₁ + m₂S₂)/m₃
