"Task parallel": compute a() in parallel with b().
"Data parallel": compute a(0), a(1), ..., a(N) in parallel.
"Task concurrent" (not idiomatic, but hear me out): handle mouse events concurrently with keyboard events.
"Data concurrent" (again not idiomatic): handle events from 1000 sockets concurrently.
compute a() in parallel with b() and
handle mouse events concurrently (could be a()) with keyboard events (could be b())
differ and how does
compute a(0), a(1), ..., a(N) in parallel differ from
handle events from 1000 sockets concurrently which would be something like a(event0) a(event1)?
Don't we require the same tools for "task parallel" and "task concurrent" as well as "data parallel" and "data concurrent"? To me they don't seem orthogonal but I believe they are very much the same thing.
