I even submit tasks inside codelet's functions, at the end, without callback 
function, is that bad ?
I submit a HETRF + TRSM only when all GEMM updates on it have been executed 
and the unlocked list of GEMM when a HETRF + TRSM finishes.
I did that to reduce the number of task that StarPU has to manage at a time 
(but as far as I remember it was not really significant).
Do you think it's better to submit all the graph from the main thread than 
inside tasks ?
