Hey, Guys!
I am using spark for NGS data application.
In my case I have to broadcast a very big dataset to each task.
However there are serveral tasks (say 48 tasks) running on cpus (also 48 cores)
in the same node. These tasks, who run on the same node, could share the same
dataset. But
might look into putting the data
into a fast store like Cassandra - that might help depending on your use case.
Cheers,
Ashic.

When you say tasks, do you mean different applications, or different tasks in
the same application? If it's the same program, they should be able to share
the broadcasted value. But given you're asking the question, I imagine they're
separate
