[Starpu-devel] Strange error " <starpu_task_submit> returned unexpected value: <-19>"

[Keisuke Fukuda <fukuda@matsulab.is.titech.ac.jp>]

Dear all,

I've been seeing a strange error,

StarPU function <starpu_task_submit> returned unexpected value: <-19>

My code is calling starpu_task_submit() as the samples do,  like

int ret = starpu_task_submit(task_ulist);
STARPU_CHECK_RETURN_VALUE(ret, "starpu_task_submit");


The failing task uses partitioning and combined workers features.
I set STARPU_SCHED=pheft and it seems to be causing the problem,
because everything's fine with STARPU_SCHED=heft .

The error still happens even if I stop using partitioning feature on the task.

Is there something wrong with pheft scheduling or any point that I
should take care?
I searched the StarPU source code but couldn't find what -19 or 19 means.

Please tell me if further information is necessary.

Thank you.
