On running VTune on a 3.4Ghz system, I notice the following on one particular module.</DIV> <DIV></DIV> <DIV>Clocktick Events: 10,529,800,000</DIV> <DIV>Bus Data Ready from the processor events: 168,200,000</DIV> <DIV></DIV> <DIV>Here's my analysis on this. The total time this module spends on "bus" (i.e getting data from memory onto cache) is 168,200,000/800Mhz (FSB is 800 MHz and the Bus data ready event is in bus clocks). Itturns out to be .21s. The total run was about ~4sec. Can I conclude that FSB is not being saturated because of this ? Are there any better ways to know how much of FSB is being used ?</DIV> <DIV></DIV> <DIV>Any help is greatly appreciated.</DIV> <DIV></DIV> <DIV>Thanks</DIV> <DIV></DIV> Sat, 19 Mar 2005 01:21:33 GMT https://community.intel.com/t5/Analyzers/VTune-Counters-Help/m-p/993898#M11630 gayu1 2005-03-19T01:21:33Z
