The Memory Bandwidth Allocation (MBA) test iterates through all possible MBA allocations, from 10% (ALLOCATION_MIN) to 100% (ALLOCATION_MAX) with increments of 10% (ALLOCATION_STEP) at each iteration. During each iteration the test measures the actual memory bandwidth NUM_OF_RUNS times to determine the impact of MBA on actual memory bandwidth. After the MBA test completes all the memory bandwidth measurements are parsed into an array. One array for resctrl Memory Bandwidth Monitoring (MBM) measurements and one array for the Integrated Memory Controller (iMC) measurements. Each array has a hardcoded size of 1024 that is large enough to hold the current test data, but this hardcoded value makes the implementation difficult to understand. It will not be clear that this array needs to be reconsidered if any of the test parameters are changed. Replace the magic constant as array size with the test parameters the array size depends on.
