assume_aligned not recognised by compiler

[Amlesh_K_]

Hi all,

I am getting the following remark while compiling.

remark #7867: This directive is misplaced or not supported on this platform.
!dir$ assume_aligned pnm : 64

Here pnm is an array of dimensions (16,27)

Intel compiler is latest.

Please suggest what is wrong and what to do?

Thanks.

By "latest", do you mean V16.0 ?

The "assume_aligned" directive is only allowed to reference dummy arguments.

What is the declaration for your array pnm?

If this is a local array or one declared in a module, and you want to force/enforce a certain alignment, you can use

!dir$ align : 64 :: pnm

                --Lorri

Hi Lorry,

Actually I have V 15.2.

The array is like this -

real(kind=8), intent(in) :: pnm(16,27)   ,ie, an intent(in) variable. Its been sent from some other module.

!dir$ assume_aligned must be placed in the executable code, close above the first loop or assignment where you want it visible.  I haven't seen it used on other than a single subscripted variable.

[Martyn_C_Intel]

Tim is correct. The documentation doesn't explain that, so I have filed an issue for it to be updated. The same applies also to the ASSUME directive.

Placing the directives in between the declaration and executable sections is also OK.

Okay. I'll check with the suggestions.

Thanks.
