+SimGrid (2.96) unstable; urgency=low
+
+ AKA SimGrid 3 rc 2.
+
+ XBT:
+ * New! Exception handling with setjmp or such (code from OSSP ex) [MQ]
+ This deprecates the xbt_error_t mecanisms.
+ It modifies (simplifies) all XBT and GRAS API.
+ MSG API keeps unchanged (exceptions raised by XBT are catched from
+ within MSG and masked with existing error handling facilities)
+
+ SURF:
+ * New! Add a FATPIPE model. [AL]
+ * New! Add a parallel task model. [AL]
+ * New! Add automatically a loopback interface (in the default
+ network model) if none was precised.
MSG
- * Implement MSG_get_msgload [MQ, AL]
+ * Bugfix: MSG_process_resume now works with the current running process.
+ [AL]
+ * New! Add MSG_parallel_task_create and MSG_parallel_task_execute. [AL]
+ * Modification of MSG_task_get_compute_duration. Once a task has been
+ processed, the value returned by this function is now equal to 0. [AL]
+ * New! Add double MSG_task_get_remaining_computation(m_task_t task) and
+ MSG_error_t MSG_task_cancel(m_task_t task). Add a state
+ (MSG_TASK_CANCELLED) to MSG_error_t corresponding to the cancelation
+ of a m_task. For now, MSG_task_cancel only works with computation
+ tasks. [AL]
+ * New! Add double MSG_get_host_speed(m_host_t h) that returns the speed
+ of the processor (in Mflop/s) regardless of the current load on the
+ machine. [AL]
+ * API Change: use proper naming convention for MSG_getClock and
+ MSG_process_isSuspended: MSG_get_clock and MSG_process_is_suspended.
+ [AL]
+ * New! Add void MSG_task_set_priority(m_task_t task, double priority).
+ This function changes the priority of a computation task. This priority
+ doesn't affect the transfer rate. A priority of 2 will make a task
+ receive two times more cpu power than the other ones. This function
+ has been added to suit the needs of Nguyen The Loc and hasn't been that
+ much tested yet. So if it fails, please report it and send me your code.
+ [AL]
+ * API Change: removed all functions and types that were marked "deprecated"
+ since many months. Renamed MSG_global_init_args to MSG_global_init.

+SimGrid (2.95) unstable; urgency=low
+
+ XBT
+ * Steal some nice code to GNU pth to fix context detection and usage [AL]
+ * Cleanup in the xbt_config API; add configuration callbacks. [MQ]
+ * Cleanup in the initialization API: the unused "defaultlog" is dead. [MQ]
SURF
* Bugfix: Allow absolute paths for platform description files [MQ]
* Bugfix: do free the variables after use. Leads to drastic performance
improvement [AL]
+ * Implement max_duration (ie, timeouts) on resources [AL]
+
+ MSG
+ * Implement MSG_config to configure MSG at runtime. xbt_cfg test on a real
+ case ;) [MQ]
+ * Implement MSG_channel_select_from() to help GRAS now that SURF provide
+ the needed support (timeouts) [AL]
GRAS (new features)
+ * Implement measurement sockets. You can now get the bandwidth between two
+ hosts thanks to AMOK (see below). [MQ]
* gras_datadesc_dynar() builds a dynar type descriptor, allowing to send
dynar over the network (yeah) [MQ]
* Real (even if simplistic) implementation of gras_os_myname() on RL [MQ]
* simple/static token-ring example. [Alexandre Colucci and MQ]
+ * Use MSG_channel_select_from() and remove the *slow* hack we had to put
+ in place before [MQ]
GRAS (bug fixes)
* Differentiate the types "char[22]" and "unsigned char[22]" in automatic
the ones which are less than 100k; bigger messages still have the issue)
* Array size pushed by the field, not by the field type (or each
and every long int will push stuff to the cbps) [MQ]
+ * use select() to sleep since it allows to portably sleep less than one
+ second. [MQ]
GRAS (minor cleanups)
* <project>.Makefile.local (generated from gras_stub_generator) |MQ]:
- Do clean .o files
- Compile with -g
- * Callbacks now receive the gras_datadesc_type_t they work on as argument.
+ * Type Callbacks now receive the gras_datadesc_type_t they work on as argument.
* type category 'ignored' killed as it was never used and were difficult
to transmit.
* whether a type can cycle or not is now a flag, leaving room for more
flags (as "ignored", if we feel the need one day ;)
* Rename raw sockets to measurement sockets since "raw" has another
- meaning in networking community.
+ meaning in networking community.
- --
+ AMOK
+ * Advanced Metacomputing Overlay Kit introduction. It is based over GRAS
+ and offers features not belonging to GRAS but that most applications
+ need. One day, it may be a set of plugins loadable at runtime.
+ * New module: bandwidth
+ bandwidth measurement between arbitrary nodes running this module. [MQ]
