Figure 1. Makespan comparison for different grid environments when number of processing nodes is
fixed to 16 and number of task varies from 8 to 100

SPMinMin. Under this grid environment, if we
keep on increasing the tasks while keeping grid
size constant, makespan of SPMinMin improves as
shown in Figure 1a. For the same grid environment
performance of SPMinMin is much better than
MinMin for smaller grid as shown in Figure 2a.

In a situation when heavy task demand less
security but high speed nodes are more secured,
the two behaves similar for larger grid as shown in
Figure 1b. For the same situation, it is also observed
that for fewer grid nodes, SPMinMin behaves bet-
ter than MinMin as depicted in Figure 2b.
