[Starpu-devel] StarPU v1.3.3 available

[Nathalie Furmento <nathalie.furmento@labri.fr>]

All,

The release 1.3.3 of StarPU is available, with the following changes

New features:
  * New semantic for starpu_task_insert() and alike parameters
    STARPU_CALLBACK_ARG, STARPU_PROLOGUE_CALLBACK_ARG, and
    STARPU_PROLOGUE_CALLBACK_POP_ARG which set respectively
    starpu_task::callback_arg_free,
    starpu_task::prologue_callback_arg_free and
    starpu_task::prologue_callback_pop_arg_free to 1 when used.
    New parameters STARPU_CALLBACK_ARG_NFREE,
    STARPU_CALLBACK_WITH_ARG_NFREE, 
    STARPU_PROLOGUE_CALLBACK_ARG_NFREE, and
    STARPU_PROLOGUE_CALLBACK_POP_ARG_NFREE which set the corresponding
    fields of starpu_task to 0.
  * starpufft: Support 3D.
  * New modular-eager-prio scheduler.
  * Add 'ready' heuristic to modular schedulers.
  * New modular-heteroprio scheduler.
  * Add STARPU_TASK_SCHED_DATA
  * Add support for staging schedulers.
  * New modular-heteroprio-heft scheduler.
  * New dmdap "data-aware performance model (priority)" scheduler

Changes:
  * Modification in the Native Fortran interface of the functions
    fstarpu_mpi_task_insert, fstarpu_mpi_task_build and
    fstarpu_mpi_task_post_build to only take 1 parameter being the MPI
    communicator, the codelet and the various parameters for the task.

Small features:
  * New starpu_task_insert() and alike parameter STARPU_TASK_WORKERIDS
    allowing to set the fields starpu_task::workerids_len and
    starpu_task::workerids
  * New starpu_task_insert() and alike parameters
    STARPU_SEQUENTIAL_CONSISTENCY, STARPU_TASK_NO_SUBMITORDER and
    STARPU_TASK_PROFILING_INFO
  * New function starpu_create_callback_task() which creates and
    submits an empty task with the specified callback
  * Use the S4U interface of Simgrid instead of xbt and MSG.

Small changes:
   * Default modular worker queues to 2 tasks unless it's an heft
     scheduler
   * Separate out STATUS_SLEEPING_SCHEDULING state from
     STATUS_SLEEPING state
     When running the scheduler while being idle, workers do not go in
     the STATUS_SCHEDULING state, so that that time is considered as
     idle time instead of overhead.

The 1.3 release serie brings among other functionalities

- a MPI master-slave support,

- a tool to replay execution through SimGrid,

- a HDF5 implementation of the Out-of-core,

- a new implementation of StarPU-MPI on top of NewMadeleine,

- implicit support for asynchronous partition planning,

- a resource management module to share processor cores and accelerator
devices with other parallel runtime systems, ...
