EXPERIMENTAL STUDY
using equation (iii). The effect of the number of
failed nodes on the turnaround time for varying
number of modules of the job and cluster architec-
ture is presented in Figure 1. For the same job and
cluster architecture, effect on the reliability of the
job execution is shown in Figure 2. Result of the
experiment with 15 number of modules resulted in
reliability values as low as 0.021. Since the value
Simulation experiments were carried out to ob-
serve the behavior of the model. Using equation
(i), the turnaround time of the job is observed
corresponding to the different number of failing
nodes. For each allocation pattern, reliability with
which the job can be executed is also calculated
