Hi Chris,

FYI, I just verified that TPR#16479 has been fixed in 10.2.

- Mat

Code:
% pgf90 -Minfo=accel loop.F -fast -ta=nvidia -o loop.out -V10.2; loop.out
looptest:
     87, Generating copyin(ubar(1:nx,3:ny-2,2:nz-2))
         Generating copyin(u(1:nx,3:ny-2,2:nz-2,1:3))
         Generating copyout(u(3:nx-2,3:ny-2,2:nz-2,2))
     89, Loop is parallelizable
     90, Loop is parallelizable
     94, Loop is parallelizable
         Accelerator kernel generated
         89, !$acc do parallel
             Cached references to size [260x3] block of 'u'
             Cached references to size [260] block of 'ubar'
         90, !$acc do parallel
         94, !$acc do vector(256)
