where is instruction throughput menu - Visual Profiler Version 3.1 Display the summary profiler tabl

The help file says
“Display the summary profiler table. It has the following columns for each GPU method:

instruction throughput”

If I import a .csv
goto “view|summary table”
I get a table with a row per kernel and 2 rows for memory transfers
BUT I can never get a column of data for instruction throughput.

Has anybody got this to work under Linux (I have Centos)?
I am probably missing something obvious but the help and
doc do not seem to tie up exactly with version 3.1 of the profiler.
And its difficult to prevent the profiler crashing
(I suspect it does this when it tries to divide by zero…)

Any help would be most welcome
