[Swift-user] regarding Swift/Turbine compiler

[Hao Yang]

Hi, all:

I am trying Swift/Turbine Compiler (STC). It seems that for foreach loops,
the default mode is to run  every iteration locally, if @async annotation
is provided, then the iterations will be launched on other remote turbine
engines, if there is app function inside a iteration, the iterations will
be launched on workers. I am wondering what is the criteria for making
these decisions (whether to run locally, on other engines or on workers) if
the goal is to optimize the performance?  If @unroll annotation is used to
optimize performance, how can one choose a good unrolling factor?

Thank you.
