How can I get more detail info from compiler about vectorization status of building a kernel

[susangao]

Hi all,

As using icc, I hope when using Intel OpenCL, I can get more detail infos about auto vectorization status. Now I can get to know which kernel is vectorized, is there a way (OpenCL kernel build option) for me to know more compiler's opinion about the no vectorized kernel?

Seems that options for clBuildProgram are very limited, is there a way to use more options that kernel compiler can understand? (Such as those optimization ones in icc)

Thank you for reading my question.

You can see exactly what optimizations the compiler is doing using the Intel OpenCL Offline Compiler as well as set the instruction sets it builds for.

Hi Susan,

As Jim said, you can use the intel offline compiler and examine the code which is generated by the vectorizer.
