Hi there,

We are starting to look at possibly using StarPU as a runtime/backend for a
compiler that we are developing. I have a question regarding edges connecting
codelets to one another.
Does StarPU have support for "gated" functionality between the different
incoming/outgoing edges from a codelet. For example, given a node that has
two incoming edges (dependences), is there
a way to cause the codelet to execute when only one of the incoming edges
resolves rather than executing when both are resolved. Intel TBB flow graphs
have this support, and I was wondering
if there is something similar in StarPU. If so, can you point me to some
examples/documentation where this used?

thanks
