-SimGrid (3.22) NOT RELEASED (Release Target: December 21. 2018, 22:23 UTC)
+SimGrid (3.23) NOT RELEASED (Release Target: June 21. 2019, 15:54 UTC)
-Java:
- - Expose host load plugin: loadInit, getCurrentLoad, getComputedFlops, getAvgLoad
- - Hide the examples into examples/deprecated. New users should use Python.
+XBT:
+ - Drop xbt_dict_dump.
+
+Fixed bugs:
+ - #326: Valgrind-detected error for join() when energy plugin is activated
+
+----------------------------------------------------------------------------
-Core:
- - Replace our own code to display a backtrace (that was forking addr2line)
+SimGrid (3.22) April 1. 2019
+
+The Easter Chrismas Release (this one is somewhat late).
+
+Python:
+ - We are excited to introduce the SimGrid/S4U interface to your neighborhood
+ - Not complete yet: asynchronous activities (amongst others) are still missing
+ - Still ongoing: the interface may change in the future. We need more
+ testers! Please report any glitches.
+ - No new project using Java should start now. Please switch to Python.
+
+General:
+ - Some of the internal cleanups may lead to speed improvements:
+ - The hard limitation on the amount of simulated actors with
+ Java+Mac was removed. Now, the available memory is the only limit.
+ - Our refcounting was tidyied, leading to 10% speedups in some cases.
+ - We are still working on making our code robust to the actor kills
+ and hosts' churn. Things are improving, but it's not perfect yet.
+ - Replaced our own code to display a backtrace (that was forking addr2line)
with the Boost.Stacktrace library.
You won't see your backtraces without this optional dependency.
- Bump cmake dependency to 3.5 (provided by Ubuntu 16.04).
+ - Stop setting random seed with srand() at initialization.
+
+XML
+ - In <host> and <peer>, 'availability_file' is now 'speed_file'.
+ XML file version remains 4.2 since old files are still compatible.
+
+Java:
+ - Process termination which was broken at version 3.21 has been repaired.
+ - Expose host load plugin: loadInit, getCurrentLoad, getComputedFlops, getAvgLoad
+ - Hide the examples into examples/deprecated. New users should use Python.
MSG:
- Drop MSG_process_create_from_stdfunc() from the API.
This C++ function was a pimple in the C API, made necessary at some
point by the Java bindings. This is fixed now.
- Hide the examples into examples/deprecated. New users should use S4U.
+ - MSG_process_create and MSG_process_attach now crash if the host used
+ to run this process is off.
+ - Fix the protype of MSG_process_on_exit()
+ Now use (int,void*) callbacks instead of (void*,void*) ones.
+ The implementation was ways too messy to actually work, I guess.
+
+SMPI:
+ - Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache
+ too often and provide more accurate timings.
+ - Add -gdb, -lldb, and -vgdb shortcuts to help debug MPI codes with smpirun
+ - MPI_Alltoallw support
+ - Partial MPI nonblocking collectives implementation: MPI_Ibcast, MPI_Ibarrier,
+ MPI_Iallgather, MPI_Iallgatherv, MPI_Ialltoall, MPI_Ialltoallv, MPI_Igather,
+ MPI_Igatherv, MPI_Iscatter, MPI_Iscatterv, MPI_Ialltoallw.
+ - MPI_Request_get_status, MPI_Status_set_cancelled, MPI_Status_set_elements
+ support
+ - Basic implementation of generalized requests (SMPI doesn't
+ allow MPI_THREAD_MULTIPLE) : MPI_Grequest_complete, MPI_Grequest_start
XBT:
- Drop sg_cmdline. Please use xbt_cmdline instead.
-fsplit-stack is the way to go nowadays when using threads.
- Drop the xbt_os_thread_t module (now unused)
- Drop xbt_ex_display(), use simgrid::xbt::log_exception() instead.
+ - Drop xbt_str_join_array().
+ - Drop cunit, use Catch2 instead.
+
+Kernel:
+ - Many cleanups in the kernel::activity namespace. This was long
+ overdue, and shall open the path to many future endeavors.
Fixed bugs:
+ - #132: Java: a process can not shut down its own host
+ - #220: S4U: detached send causes exception if sender terminates soon after sending
- #261: Document the parameters of parallel execution's constructor
+ - #300: [s4u] BarrierPtr is missing
- #314: SMPI args internal cleanup
- #316: Fix a bug related to the CPU utilization of multi-core VM
+ - #318: Invalid trace file when using option --cfg=tracing/smpi/display-sizes:yes
+ - #324: S4U: Attempting to create an actor on turned off host segfaults instead of throwing
+ - #325: Turning off a host has different behavior on sleeping actors and computing actors
----------------------------------------------------------------------------
* VM I/O related things:
- Ignored parameter of vm_create: core_nb, disk_path and disk_size.
- Unimplemented save/restore methods
- * MSG_as_router_get_property_value() was redundent with
+ * MSG_as_router_get_property_value() was redundant with
MSG_environment_as_get_property_value().
- Removed MSG_as_router_*propert*() functions
- Added MSG_environment_as_set_property_value() for consistency
flops that a <host>, <peer>, <cluster> or <cabinet> can deliver per second.
- In <trace_connect>, attribute kind="POWER" is now kind="SPEED".
- In <host> and <link>, attributes availability and state are gone.
- It was redundent with state and availability traces, and with peak values.
+ It was redundant with state and availability traces, and with peak values.
- In <cluster>, attributes availability_file and state_file are gone.
It was too complex and unused.
- Kill <gpu>. Was not doing anything.
