| c Cache blocking params. These values are good for most |
| c RISC processors. |
| c FFT parameters: |
| c fftblock controls how many ffts are done at a time. |
| c The default is appropriate for most cache-based machines |
| c On vector machines, the FFT can be vectorized with vector |
| c length equal to the block size, so the block size should |
| c be as large as possible. This is the size of the smallest |
| c dimension of the problem: 128 for class A, 256 for class B and |
| c 512 for class C. |
