PPCG 0.07 was released containing one main change:

Support hybrid tiling
Basic hybrid tiling can now be enabled using the
hybrid
option. It currently only applies to stencils with a single statement.For example, hybrid tiling can be applied to the input (say
heat2d.c
)#define N 3072 #define T 512 void heat(float A[2][N][N]) { #pragma scop for (long t = 0; t < T; t++) { for (long i = 1; i < N  1; i++) for (long j = 1; j < N  1; j++) A[(t+1)%2][i][j] = (1/9.0f) * (A[t%2][i][j] + A[t%2][i1][j1] + A[t%2][i1][j] + A[t%2][i1][j+1] + A[t%2][i][j1] + A[t%2][i][j+1] + A[t%2][i+1][j1] + A[t%2][i+1][j] + A[t%2][i+1][j+1]); } #pragma endscop }
by invoking
