I'm tring to calculate the L2 miss ratio of a program on the platform of Intel Core2 michroarchitecture.
I use vtune to find out the hotspot of the program, but when I try to edit the code through double-click the hotspot code line it says that"
I'm still confused by how to calculate the L1, L2 cache miss ratio after reading many related posts.
I'm trying to use Vtune to get the L1I, L1D, and L2 cache miss ratio on the platform of Intel Xeon core microarchitecture.
I try to use VTune™ Amplifier XE 2011 to test the performance hardware issues of my C code project.
Recently,I've been using Vtune to get each cache level miss ratio on different platforms.
I try to use hardware sampling event to calculate the L1,L2 miss, but it says that" unable to open shared library:libivytown.so
I try to use hardware sampling event to calculate the L1,L2 miss.
I've learned the following formula to calculate the L1,L2,L3 Miss rate from another post which is given by @Kirill Rogozhin (Intel):
My machine is Ivybridge E5-2692v2, but when I try to use -collect snb-memory-access ,it says that "This analysis type is not applicable to the current machine michroarchitecture".
I want get 'cpu stall' using vtune.which event should i use?How to use? I have found two events.
I installed vtune_amplifier xe 2013 in my PC ( Intel 4core CPU) with Ubuntu kernel. Below are my quetions.
The event ‘L2_LINES_IN.SELF.ANY’ used to get L2 cache can’t be found in linux
