Plain diff
What's in this MR?
- Static schedule now includes early and late logical start for each scheduled element;
- A new multi-threaded
ParallelScheduler; - A new simple thread pooling class
ThreadPool; - The log class allows to specify default values through env variables;
- Updated C-P model to work with both data and tokens (it is now possible to generate a static sheduling without
forwardDims()with the defaultOperatorImplC-P model).
Example:
This is the scheduling obtained for the graph that follows:
