Parallelized preparation across nodes, cores, and SIMD lanes

Twelve parallel insert batches start in two rows, with A on the left and B on the right. Four enter each compute node. The core close-up crops the upper row and keeps the bottom two batches. Only B fades out; A stays fully visible and is drawn twice. The original A moves into ordering across CPU cores 1 and 3, and its identical copy moves right into pre-aggregation across CPU cores 2 and 4. Both operations process the same input A in parallel. No batches merge. Each complete data graphic spans its two cores. The existing synchronized transition into SIMD and +1 example remain: 74, 48, 100 and 32 become 75, 49, 101 and 33 in four blue outlined value cards. Core roles and values are illustrative.
