Hi,
How can we achieve work isolation among the nodes of a dependency graph or generally a flow graph? I am defining the node as :
tbb::flow::continue_node<tbb::flow::continue_msg> nd (g,[=](const tbb::flow::continue_msg &msg)
{
int tid = tbb:this_task_arena::current_thread_index();
tbb::this_task_arena::isolate([& {
// do some work with nested parallelism or nested subgraphs
});
});
Defining a node as above and using isolate does not prevent tid to get when idle other nodes of the graph? How can we prevent tid to jump out of this node?
Thank you.
