Small interface issue in Kernel Builder... the y-axis of the EU chart only shows 7 threads on Ivy Bridge EUs.
I thought IB EUs have 8 threads and Haswell EUs have 7 threads?
The chart shows the number of threads that were active on your kernel execution. If you are certain that all 8 HW threads were active, can you please share with me a Kernel Builder session file + kernel code so I can try it myself?
Also - if you can specify the exact model of your Ivy Bridge unit and driver version, that could be helpful.
It's a Celeron 1037U (Ivy Bridge with 6 EUs).
I'll DM you the kbsess file.
Not a bug.
Oren pointed out that the clicking again on the plot reveals an EU HW thread chart.
