I need your help.

My application is running on IA32.  I use mkl_malloc(), but, I don't know exactl what  i should enter number is 32 or 64 for IA32.

Jungmin,

A power of 2 is expected. 8 will work on a 32 bit machine. Default is 32 if you enter anything that is not a power of 2.

The alignment matters more when you are working with SSE or AVX, for performance reasons.

I hope that helps.
