Figure 1: The scalability of IRSmk on a 48-core AMD machine. The x-axis is the number of cores, while the y-axis is the execution time in seconds.
Table 1 shows how ScaAnalyzer monitors these three types of data objects. ScaAnalyzer identifies each of the monitored data objects using a unique ID and records the associated memory range allocated
Figure 2: The workflow of ScaAnalyzer. There are three components: data collector, analyzer, and  vi-sualizer
Figure 3 shows the scalability test of LULESH from 1 to 48 cores available in the AMD machine
