Insights AVX-512 Programming: Extracting Column Subtotals from a Table

I hope that the example I'm presenting here will be of interest to some of you. The program in the article uses a list of monthly expenses for four months in eight categories, such as mortgage, homeowner insurance, utilities, and so on. The example program can calculate the subtotals of any combination of the eight categories in a loop that has three lines of code. The heart of the loop reads all eight values for a given month in one operation, but writes only the ones of interest into a 32-byte destination register (that could hold all eight values, if necessary). The remainder of the loop adds the items of interest to an accumulator, and starts the loop body again until the data is exhausted.
