XcalableMP Fortran

!$xmp template t(10,10)
!$xmp distribute t(block,block) onto p

integer :: a(10,10)
!$xmp align a(j,i) with t(j,i)
!$xmp loop on t(j,i)
do i=1, 10

do j=1, 10
a(j,i) = i * 10+j

3.3 array Construct
The array construct is for work mapping of array assignment statements.
XcalableMP C
#pragma xmp align a[i] with t[i]
:
#pragma xmp array on t[0:N]
a[0:N] = 1.0;
XcalableMP Fortran
!$xmp align a(i) with t(i)
:
!$xmp array on t(1:N)
a(1:N) = 1.0
