Scheduling Method:

avoid distribution of statements:

Try to avoid constants in the first dimension of a statement's schedule. In many cases this leads to more compact schedules (default).

only non-negative coefficients:

The coefficients in the schedule will be strictly non-negative. This is a real restriction, so do not use it if you do not need it (intended for internal use).

shift schedules:

With this option enabled, the schedules will be non-negative in all dimensions (default).
