cMSG:
* Interface improvement:
- Rename MSG_host_is_avail(h) to MSG_host_is_on(h)
+ - Sanitize the interface in MSG_task_ module:
+ - Merge two functions that were close enough but misleading:
+ set_compute_duration(t) -> set_flops_amount(t)
+ get_remaining_computation(t) -> set_flops_amount(t)
+ - set_data_size(t) -> set_bytes_amount(t)
+ get_data_size(t) -> get_bytes_amount(t)
- Massive cleanups in the functions related to the energy
jMSG:
* Interface improvement:
- Rename Host.isAvail() to Host.isOn()
+ - Rename Process.currentProcess() to Process.getCurrentProcess()
+ - Rename Task.setDataSize() to Task.setBytesAmount()
+ - Merge Task.getRemainingDuration() and Task.getComputeDuration() into Task.getFlopsAmount()
+ * Bug fixes:
+ - #18874: Actually allows the GC to reclaim tasks
SIMIX:
* New functions
For example, a communication is a sort of synchronization involving
the communicating processes (that may block until the exchange) and
the platform. The same can be said from computations, etc.
+ * Bug fixes:
+ - #18888: segfault when a process ends before its kill_time
SMPI:
* New functions
- Constant times can be injected inside MPI_Wtime and MPI_Test through options smpi/wtime and smpi/test
- InfiniBand network model added : Based on the works of Jerome Vienne (http://mescal.imag.fr/membres/jean-marc.vincent/index.html/PhD/Vienne.pdf )
- When smpi/display_timing is set, also display global simulation time and application times
+ - Have smpirun, smpicc and friends display the simgrid git hash version on --git-version
* Collective communications
- SMP-aware algorithms are now dynamically handled. An internal communicator is created for each node, and an external one to handle communications between "leaders" of each node
- MVAPICH2 (1.9) collective algorithms selector : normal and SMP algorithms are handled, and selection logic is based on the one used on TACC's Stampede cluster (https://www.tacc.utexas.edu/stampede/).
- Add a xbt_heap_update function, to avoid costly xbt_heap_remove+xbt_heap_insert use
- Add a xbt wrapper for simcall_mutex_trylock (asked in [#17878])
- Add two new log appenders : rollfile and splitfile. Patch by Fabien Chaix.
-
+ Build System
+ * Tracing is now always enabled (no way to turn it out)
+ * Move headers around to sort them out on installed systems:
+ - instr/instr.h -> simgrid/instr.h
+ - instr/jedule/* -> simgrid/jedule
+ - simdag/datatypes.h was removed
+ - simdag/simdag.h -> simgrid/simdag.h
+ - msg/datatypes.h was removed
+ - msg/msg.h -> simgrid/msg.h
