There are two horizontal rows and six columns with six rectangular blocks each and both rows are connected via dashed lines. The first row is labeled C P U 0 and the second row is labeled C P U 1. The dashed lines depict the Time slots between the columns that start from 0 to 600 in an increment of 100 units. Row 1 (C P U 0) has elements A subscript 0, B subscript 0, A subscript 0, B subscript 0, A subscript 0, B subscript 0. Row 2 (C P U 1) has elements B subscript 1, A subscript 1, B subscript 1, A subscript 1, B subscript 1, A subscript 1. Every alternate column in two rows is highlighted. There is a forward arrow labeled Request 1 from row 1, column 1 A subscript 0 to row 2, column 1 B subscript 1. There is an upward arrow labeled Reply 1 from row 1, column 2 A subscript 1 to row 2, column 2 B subscript 0. Again, there is a forward arrow labeled Request 2 from row 3, column 3 A subscript 0 to row 3, column 3 B subscript 1. There is an upward arrow labeled Reply 2 from row 4, column 4 A subscript 1 to row 4, column 4 B subscript 0. Row 1, column 3, is labeled Thread A subscript 0 is running.
