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 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!
