How can I ALLOCATE an array so that it aligned with a 32-byte boundary? I need to do this for optimum performance when calling Intel's vectorized math libraries...

thanks!

You can't specify alignment with ALLOCATE. Best I can recommend is to malloc n+32 bytes, add 31 to the base address and then AND off the low five bits. Assign this to an integer POINTER for your array pointer. Don't forget to save the original allocated address for the free/
