[ExM Users] scaling Turbine on Vesta

Hi,

Trying to scale up a simple leaf function on Vesta. It seems that the leaf
function runs at max 259 times and beyond that either it does not return
any results or crash, but I do not see any error messages or other
indications either.

On Vesta, an example is at /home/ketan/turbine-output/2014/04/14/23/04/06

Any clue on this?

The Swift source looks as follows:

import io;

@dispatch=WORKER
(int v) leaf_main(string A[]) "leaf_main" "0.0" "leaf_main_wrap";
main
{
  int rc[];
  foreach i in [0:9999:1]{
    rc[i] = leaf_main([fromint(i)]);
  }
}


Thanks,
Ketan
