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!

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.

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.
