I basically have the graph I want with each node being a two node cycle graph
Task <-> Tag.

Is there no way to merge those two ? and have the DAG with task names in the
nodes (from task ?) and the dependences (from tags ?) ?

Also, I now have a lot of messages at the end of my program's execution.
And what looks like the same messages fro starpu_fxt_tool:
94 warnings of the form
profiling:/.../StarPU/src/.libs/libstarpu_1.0_la-footprint.gcda:Merge
mismatch for summaries

It seems the relation between tags and tasks was not implemented. You
can try the latest svn, or the attached patch.
