SimGrid (3.31.1) NOT RELEASED YET (v3.32 expected June 21. 2022, 09:13 UTC)
+S4U:
+ - Added the xbt_enforce macro. This has the same syntax as xbt_assert. The only difference is that an AssertionError
+ exception is thrown if the condition is not satisfied, instead of calling abort().
+
Python:
- Added the following bindings / examples:
- Comm (now 100% covers the C++ interface):
- Engine:
- Engine.host_by_name [example: examples/python/comm-host2host/]
- Engine.mailbox_by_name_or_create [example: examples/python/comm-pingpong/]
+ - Engine.set_config
- Mailbox: Mailbox.ready [example: examples/python/comm-ready/]
+ - Ptask [example: examples/python/exec-ptask/]:
+ - this_actor.exec_init
+ - this_actor.parallel_execute
+ - Exec.suspend
+ - Exec.wait_for
+ - Added an AssertionError exception that may be thrown in case of error. For instance, creating tow hosts with the
+ same name will now throw this exception instead of killing the interpreter.
Platform description & visualization:
- More robust sanity checks for platforms, to reject unallowed topologies with
demonstrates how we can generate a nice graphical representation of the
platform.
+General:
+ - SimGrid now requires a compiler with C++17 support.
+ - Modified the host_by_name functions:
+ - Now, they return only hosts, not VMs, and in a much more efficient way.
+ - If one wants to find a VM by name, he now needs to know the host on
+ which it runs and call vm_by_name (or manually iterate over the list of hosts)
+
Tools:
- Enhancements to the graphicator tool:
- Allow to dump the platform topology as a CSV file representing the edges
(FG: issues on Framagit; GH: issues on GitHub)
- FG#105: "Variable penalty should not be negative!" with in-flight messages and bandwidth profiles
- FG#109: Application time reported by --cfg=smpi/display-timing:yes is wrong
+ - FG!109: Trigger new engine solve upon host events such as host on/off
- FG#110: Wait_any does not trigger new model solve when host events occur
+ - FG#111: Wrong execution time in rare cases when using multicore
