[Starpu-devel] [PATCH 0/5] Merge heft and dmda.

[Cyril Roelandt <cyril.roelandt@inria.fr>]

Hi,

The following five patches merge heft and dmda. They work well on my machine, 
I
just haven't run any benchmark. Samuel, the last time I hacked  the 
schedulers,
you ran a benchmark on Plafrim, could you run it again and tell me if these
patches affect the performance ?

The patches mostly consist in moving pieces of code from heft.c to
deque_modeling_policy_data_aware.c. In the second patch, you may notice this
code in _starpu_fifo_pop_first_ready_task:


if (STARPU_UNLIKELY(!task))
        return NULL;

It is a workaround for a bug I discovered recently (and probably introduced
myself) that I will be bothering you with soon enough. Anyway, I do not think
it is a bad thing to check whether the task is NULL, plus it should not cost
much CPU cycles if the compiler is good at branch prediction.

I have not tested the StarPU-Top support, but, well, it should be working.

Cyril Roelandt.
