SimGrid (3.11) NOT RELEASED; urgency=low
- TENTATIVE RELEASE GOALS for 3.11:
- * Switch to tesh.pl, and kill the now unused parts of xbt that seem fragile
- * Clean up CMake files (may need a full rewrite).
- Non exhaustive list of subgoals:
- - Use genuine cmake mechanisms and variables when available,
- instead of reinventing the wheel.
- - Correctly determine system and architecture (e.g. x32).
- - Correctly determine compiler type and version (e.g. clang).
- - Correctly set compiler flags according to compiler type and version.
- - Correctly set compiler flags for C++, Java, and Fortran compilers too.
- - Use git to generate the dist archive. Either use git-archive to
- generate the tarball, or keep using cmake -E tar, but use git-ls-files
- to get the list of files to pack.

+ several times
- Simcalls:
- * Simcalls are now generated by a python script
- - generate files include by simgrid
- - check that all the functions exists and propose prototypes
+ SIMIX:
+ * Protect context stacks against stack overflow. The number of protected memory
+ pages allocated on the top of each stack (1 by default) can be configured
+ with the new command line option --cfg=contexts/guard_size:<value>.
+ * Simcalls are now generated by a python script that
+ - generates files included by SimGrid
+ - checks that all the functions exist, and proposes prototypes
* Clean simcalls
- remove sem_destroy, file_set_data, comm_destroy, vm_set_state,
host_set_data, host_get_data
+ * New simcalls
+ - simcall_process_join(smx_process_t process, double timeout)
+ * Fix bug where sleeping processing could not be suspended.
SURF:
* Translate surf models from C to C++
- Generic classes for all models: Model, Resource, Action
- - A generic interface for each kind of model (cpu, network, storage
- workstation, workstationvm)
+ - A generic interface for each kind of model (CPU, Network, Storage
+ Workstation, WorkstationVM)
- C bindings
* Translate surf routings from C to C++
* Add callbacks using sigc++ or boost::signals2
- Add callback functions for resource creation/destruction
- - Add callback finctions for action state change
+ - Add callback functions for action state change
- Handle Energy as a plugin
* Replace swag by boost::intrusive
- * Add new routing model for torus clusters
+ * Add new routing model for torus clusters
+ - topology="TORUS" and topo_parameters="ndim1,ndim2,...,ndimn" parameters
+ for cluster tag
+ - see examples/platforms/torus_cluster.xml
* More documentation
SMPI:
- * hostfiles support host:nb_processes construct to deploy several processes on
- one node
+ * Hostfiles support host:nb_processes construct to deploy several processes on
+ one node.
* Collective communication algorithms should not crash if used with
improper number of nodes and report the error.
+ * SMPI now partially supports MPI_Topologies : MPI_Cart_create, MPI_Cart_shift,
+ MPI_Cart_rank, MPI_Cart_get, MPI_Cart_coords, MPI_Cartdim_get,
+ MPI_Dims_create, MPI_Cart_sub are supported.
+ * New interface to use SMPI programmatically (still depends on MSG for
+ some parts, see examples/smpi/smpi_msg_masterslave) :
+ - SMPI_app_instance_register(const char *name, xbt_main_func_t code,
+ int num_processes)
+ - SMPI_init()
+ - SMPI_finalize();
+ * Global variables privatization in MPI executables is now performed at runtime
+ with the option smpi/privatize_global_variables (default:no).
+ Limitations : Linux/BSD only, with mmap enabled. Global variables inside
+ dynamic libraries loaded by the application are not privatized (static
+ linking with these libraries is advised in this case)
+
+ Tracing:
+ * Options defined in XML work correctly now.
Java:
* New cmake option, enable_lib_in_jar, to control whether native libraries are
copied into simgrid.jar or not (ON by default). Use this option if you want
to reduce the size of the installed simgrid.jar, *and* the native libraries
are kept installed elsewhere.
+ * Surf binding with SWIG (code generated in maintainer mode only):
+ - plugin to handle callbacks
+ - CPU model only for the moment
Build System:
* Supernovae build mode is definitively removed. It was used to improve
inlining and inter-module optimizations. It is nowadays superseded by
link-time optimizations commonly available in compilers.
- * Update ns3 find lib
+ * Update ns-3 find lib. Bindings for ns-3 should work again now.
* Add boost dependency for surf++
+ * Add new macro for tests
+ - ADD_TESH(name <tesh_args>)
+ - ADD_TESH_FACTORIES(name "thread;ucontext;raw" <tesh_args>)
+
+ XBT:
+ * New functions
+ - xbt_bar_t XBT_barrier_init(unsigned int count)
+ - int XBT_barrier_wait(xbt_bar_t barrier)
+ - void XBT_barrier_destroy(xbt_bar_t barrier)
+ * Make the xbt_os_time module public
-- $date Da SimGrid team <simgrid-devel@lists.gforge.inria.fr>
* New option "enable_mallocators" to disable mallocators, for debugging
purpose ("on" by default).
- Simix:
+ SIMIX:
* Bug fixes around the resource failures: don't let the processes
survive the host they are running onto.
* Add an interface to auto-restart processes when the host in which they are
