title: Multiple CPUIDs not showing up in Gem5 simulation
body: <p>I am just starting out with gem5; I ran a program which was statically compiled using m5threads library, and ran using se.py with '-n 64' flag set. This should be simulating the program running on 64 cores [As per <a href="http://pages.cs.wisc.edu/~markhill/cs757/Spring2016/wiki/index.php?n=Main.Homework3]" rel="nofollow noreferrer">http://pages.cs.wisc.edu/~markhill/cs757/Spring2016/wiki/index.php?n=Main.Homework3]</a>, but the Exec traces only show operations from a single CPU. What am I doing wrong ?</p>
