感谢！！解决了我的问题

1、去掉 第六行的 allocatable;
2、MODULE Global_variables 放在最开始;      
3、主程序 use Compute。

    MODULE Compute
    USE Global_variables
    IMPLICIT NONE
    
    CONTAINS
    attributes ( global ) SUBROUTINE Age_add(People_d)
    INTEGER		:: I,N1
    type(Person),       allocatable              :: People_d(:)
    
    I=(BLOCKIDX%X-1)*BLOCKDIM%X+THREADIDX%X
    N1=SIZE(People_d,1)
    
    IF (I>N1) RETURN
    People_d(I)%age = People_d(I)%age + 1
 
    END SUBROUTINE
    END
    
    MODULE Global_variables
    IMPLICIT NONE

    type Person
        integer(kind=4)                        ::     age                    ! 年龄
        integer(kind=4)                        ::     height                 ! 身高
        integer(kind=4)                        ::     weight                 ! 体重
    end type
    END


    program Test
    use cudafor
    use Global_variables
    implicit none
    integer , parameter :: PersonNum = 10000
    type(Person),       allocatable              :: People(:)
    type(Person),device,allocatable              :: People_d(:)
    integer :: i
    
    allocate(People(PersonNum))
    allocate(People_d(PersonNum))
    DO i = 1, PersonNum
        People(i)%age = i
        People(i)%height = i
        People(i)%weight = i
    ENDDO
    
    People_d = People
    CALL Age_add<<<CEILING(REAL(PersonNum)/256),256>>>(People_d)
    People = People_d
    
    write(*,*) People(500)%age
    write(*,*) SIZE(People, 1)
    
    end program Test
