TITLE: Back End 1 Uop Executed

ISSUE_NAME: Backend^CoreBound^Cycles1PortsUtilized

DESCRIPTION:

Cycles where the core executed 1 uop

RELEVANCE:

This metric represents how often the core executed 1 uop in a cycle.  Depending on the instruction mix, when only 1 uop is executed, this may indicates a bottleneck since the maximum bandwidth of uops in execution was not achieved.

EXAMPLE:

SOLUTION:

If this metric is high, and you expect more than 1 uop executed per cycle you will want to look at the other Backend metrics to try and root cause why the core executed 1 uop in a cycle.
