-align array64byte

[Joe_C_4]

When attempting to use the switch "-align array64byte", I get the following error message:
          ifort: command line error: Unrecognized keyword 'array64byte' for option '-align'
Admittedly, I'm not using v13 of the compiler. (I am using v12.) Is that the cause of my problem?

Yes, it is. That's a newer option. You can use !DEC$ ATTRIBUTES ALIGN for individual arrays if you wish.

[Joe_C_4]

Follow-up question...  Is it "!DEC$ ATTRIBUTES ALIGN" or "!DIR$ ATTRIBUTES ALIGN"?

[Steven_L_Intel1]

Either will work. !DEC$ is traditional (for us), but we support !DIR$ too.
