EU Array Stalled/Idle: 34.5% of Elapsed time with GPU busy

The percentage of time when the EUs were stalled or idle is high, which has a negative impact on compute-bound applications.

GPU L3 Bandwidth Bound: 91.0% of peak value

L3 bandwidth was high when EUs were stalled or idle. Consider improving cache reuse.
