\brief This section describes the interface supplied by StarPU to interoperate with other runtime systems.

\enum e_starpurm_drs_ret
\ingroup API_Interop_Support
StarPU Resource Manager return type.
\var starpurm_drs_ret::starpurm_DRS_SUCCESS
  Dynamic resource sharing operation succeeded.
\var starpurm_drs_ret::starpurm_DRS_DISABLD
  Dynamic resource sharing is disabled.
\var starpurm_drs_ret::starpurm_DRS_PERM
  Dynamic resource sharing operation is not authorized or implemented.
\var starpurm_drs_ret::starpurm_DRS_EINVAL
  Dynamic resource sharing operation has been called with one or more invalid parameters.

@name Initialisation
\ingroup API_Interop_Support

\fn void starpurm_initialize(void)
\ingroup API_Interop_Support
Initialize StarPU and the StarPU-RM resource management module. The \ref starpu_init function should not have been called before the call to \c starpurm_initialize. The \c starpurm_initialize function will take care of this

\fn void starpurm_shutdown(void)
\ingroup API_Interop_Support
Shutdown StarPU-RM and StarPU. The \ref starpu_shutdown function should not be called before. The \c starpurm_shutdown function will take care of this.


@name Spawn
\ingroup API_Interop_Support

\fn void starpurm_spawn_kernel_on_cpus(void *data, void(*f)(void *), void *args, hwloc_cpuset_t cpuset)
\ingroup API_Interop_Support
Allocate a temporary context spanning the units selected in the cpuset bitmap,
set it as the default context for the current thread, and call user function \c f.
Upon the return of user function \c f, the temporary context is freed and the previous
default context for the current thread is restored.

\fn void starpurm_spawn_kernel_on_cpus_callback(void *data, void(*f)(void *), void *args, hwloc_cpuset_t cpuset, void(*cb_f)(void *), void *cb_args)
\ingroup API_Interop_Support
Spawn a POSIX thread and returns immediately. The thread spawned will allocate
a temporary context spanning the units selected in the cpuset bitmap, set it as
the default context for the current thread, and call user function \c f. Upon
the return of user function \c f, the temporary context will be freed and the
previous default context for the current thread restored. A user specified callback \c cb_f
will be called just before the termination of the thread.
