TLNS3D Hand Restructuring

• DELTAW needed restructuring --

  • The only non directive change
  • Artificial cross iteration dependence
  • A scalar optimization
    • Wraparound variable
  • Introduced redundant scalar computation to allow parallel loop

C BEFORE

x = f(min-1,min)

do j = min, max

y = g( x )

x = f( j, j+1 )

z = h( x )

enddo

C AFTER

do j = min, max

x = f( j-1, j )

y = g( x )

x = f( j, j+1 )

z = h( x )

enddo
