No, the scheduler in 3.1 is the same as 3.0.
However, it already does support a type of multi-threading. If a flow
graph has "islands of connectivity", the runtime will detect that and
run each of them in a separate thread. For example, a transceiver
application typically has a receive path and transmit path that are not
connected to each other in any way. In this case, a thread will be
allocated for each, and multi-core processors will run them truly in
A "thread per block" scheduler was implemented for the mblock/in-band
development on the trunk, but it has some performance limitations due to
excessive thread switching behavior at runtime. When those are solved,
we will unify the scheduler between gr-blocks and mblocks, as part of
the 3.2 release series.
