Figure 5.

Performance and strong scaling of the parallel correlation function. Top graph shows the executing time of the correlation function. The dashed horizontal line is the time taken for R to execute the correlation on a single processor. The solid line shows the time for the parallelised version within SPRINT. The bottom graph shows the strong scaling (same data, different number of processors) for the parallel correlation function within SPRINT. The straight, dashed line shows linear scaling based on the execution time of R running on a single processor.
