Finite Difference Example for T3E Cache Use II

• AA(I,J) = -B

• DD(I,J) = B+B+A*REL

• PXX = X(I+1,J)-2.*X(I,J)+X(I-1,J)

• QXX = Y(I+1,J)-2.*Y(I,J)+Y(I-1,J)

• PYY = X(I,J+1)-2.*X(I,J)+X(I,J-1)

• QYY = Y(I,J+1)-2.*Y(I,J)+Y(I,J-1)

• PXY = X(I+1,J+1)-X(I+1,J-1)-X(I-1,J+1)+X(I-1,J-1)

• QXY = Y(I+1,J+1)-Y(I+1,J-1)-Y(I-1,J+1)+Y(I-1,J-1)

• RX(I,J) = A*PXX+B*PYY-C*PXY

• RY(I,J) = A*QXX+BCa*QYY-C*QXY
