Example
This example shows how to run the Memory Access analysis on a Linux*
myApplication
app, collect data on dynamic memory objects, and evaluate maximum achievable local DRAM bandwidth before the collection starts:
vtune -collect memory-access -knob analyze-mem-objects=true -knob dram-bandwidth-limits=true -- home/test/myApplicationWhat's Next
When the data collection is complete, do one of the following to view the result:
