SimGrid (3.29.1) NOT RELEASED YET (v3.30 expected December 21. 2021, 15:59 UTC)
Main user-visible changes:
- - The SimDag API for the simulation of the scheduling of Directed Acyclic
- Graphs has been dropped. It was marked as deprecated for a couple of years.
- We finally complete the implementation of what has been called SimDag++
- internally, i.e., porting the different features of SimDag on top of S4U.
- The new way to simulate the execution of dependent activities directly by

S4U:
- Introduce on_X_cb() functions for all signals, to attach a new
callback to the signal X. The signal variables are now hidden and
only these functions should be used.
- Rational: this enables the usual deprecation schema where functions
+ Rationale: this enables the usual deprecation schema where functions
remain for 4 releases if we need to modify the signals, while the
current code with the signal variables directly visible prevents any
smooth transition.
- FG#95: Wrong computation time for multicore execution after pstate change
- FG#97: Wrong computation time for ptask+multicore+pstates
- FG#99: Weird segfault when not sealing an host
