Suppose a subroutine has two loops
loop1
loop2
Which way of writing the OpenACC directives is better? and why?
method 1
!$acc kernels
loop1
loop2
!$end acc kernels
method 2
!$acc kernels loop
loop1
!$acc kernels loop
loop2
Thanks,

Neither is better than the other. It's more personal preference and what works better for the particular context.
