Cache-Friendly Matrix Multiplication Visualization

Matrix multiplication: Tiled, B transposed A B C × = Totals: mem:27 cache hits:18 ≅66% Totals: mem:762 cache hits:682 ≅89% Totals: mem:1497 cache hits:1345≅89% Totals: mem:2232 cache hits:2010≅90% Totals: mem:2967 cache hits:2671≅90% Totals: mem:3702 cache hits:3331≅89% Totals: mem:4437 cache hits:3999≅90% Totals: mem:5172 cache hits:4668≅90%

An animated technical visualization shows tiled matrix multiplication with a transposed matrix B. Red and pink blocks move through the A, B, and C grids while memory accesses and cache hits steadily increase, reaching about 90% efficiency; the punchline is the unexpectedly beautiful, almost musical choreography of a cache-friendly algorithm. It is shared as an ironic reaction to elegant, mesmerizing engineering diagrams or overly enthusiastic praise of computer-science infrastructure.
