SimGrid (3.11) NOT RELEASED; urgency=low
TENTATIVE RELEASE GOALS for 3.11:
- * Consider the removal of Supernovae mode if no user has manifested since the
- release of version 3.10.
* Switch to tesh.pl, and kill the now unused parts of xbt that seem fragile
- * Switch to surf++, and reintegrate the hypervisor branch on top of it
* Clean up CMake files (may need a full rewrite).
Non exhaustive list of subgoals:
- Use genuine cmake mechanisms and variables when available,
- 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.
- - For Java, add an option to enable/disable the inclusion of the native
- libraries in the jar file, and avoid to duplicate these files.
+
+ The Class Release.
+
+ Tools:
+ * Normalizing pointers addresses tool for better diff between logs
+
+ Examples:
+ * Add cloud examples using new VMs
+ - examples/msg/cloud/two_tasks_vm.tesh
+ - examples/msg/cloud/simple_vm.tesh
+ - examples/java/cloud/cloud.tesh
+ - examples/java/cloud/migration/migration.tesh
+ * Add java surf examples:
+ - examples/java/surfPlugin/surf_plugin.tesh
+ - examples/java/reservationSurfPlugin/reservation_surf_plugin.tes
+ - examples/java/surfCpuModel/surf_cpu_model.tesh
+
+ TeshSuite:
+ * Add tests:
+ - msg process test
+ - msg task destroy cancel test
+ - msg_host on/off test
+ * Move all tests in testsuite to teshsuite (adding tesh files)
+ * Restructure teshsuites
+ - one folder for each kind of test
+ * Restructure AddTests.cmake
+ - unify tests names
+ - structure the order of tests (with sections)
+
+ MSG:
+ * Add virtual machine
+ - creation of a VM on a PM
+ - migration of a VM from a PM to another PM
+ * New function
+ - MSG_process_join(msg_process_t process, double timeout)
+ * New option "msg/debug_multiple_use" to help debugging when a task is used
+ several times.
+
+ 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)
+ - 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 functions for action state change
+ - Handle Energy as a plugin
+ * Replace swag by boost::intrusive
+ * Add new routing model for torus clusters
+ * More documentation
+
+ SMPI:
+ * 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.
+
+ 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 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>)
-- $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
