Crisped on the outside, thoughtful enough on the inside.
Summary
The article discusses the use of blocking to optimize cache access patterns for higher performance in matrix operations, achieving significant speed-ups for matrices exceeding the machine's cache size.
Key quotes
· 2 pulledThe first step towards higher performance is employing blocking to optimize cache access patterns.
Speed-ups of approximately sixfold are achievable for matrices that exceed the machine's cache size.
