vexprofile command

Turns profiling of VEX functions on/off

All Usages Options Examples

Usages

  1. vexprofile [-n] [-a] [-s] [-p] [-c] [-h] [-S] [start]

Running the command with the word “start” after the options (if any) start profiling. If you don’t specify any flags, profiling is turned on for all functions.

Running the command again without arguments and without the word “start” turns profiling off. The command prints the profiling statistics when you turn off profiling. So, to save the results, redirect the output when you turn profiling off.

Options

-n

(Numbers) Checks that all input and output variables are valid floating point numbers.

Certain operations on invalid arguments can result in a value of “NAN” (“not a number”). This check will warn you about occurrences of this in your VEX code.

-a

Profile all loaded functions.

-s

Profile surface (SOP) functions.

-p

Profile particle (POP) functions.

-c

Profile compositing (COP) functions.

-h

Profile channel (CHOP) functions.

-S

Profile shading functions.
