Date: Fri, 16 Mar 2007 17:13:08 +0100 From: "Guerreiro da Luz" <g.da.luz@...il.com> To: linux-kernel@...r.kernel.org Subject: decrease L2 cache size used by Linux? Am benchmarking dumb matrix multiplication in trying to perceive performance drop in case when matrix cannot fit in L2 cache. However, on my machine L2 cache is large - 2MB, so 512x512 matrix of double numbers is needed to fill the cache, and in that case multiplication is taking rather long time. So I'm wondering is there a way to control (decrease) L2 cache size used by Linux? Apologies if question inappropriate for the list.
