I downloaded 1.3 the day its release was announced :)
I now wanted to try it, so i pieced it together from orte-iof --help:
- started an mpirun with 4 process
- opened a new terminal
- did ps to find the mpirun's pid
- then: orte-iof --pid 8449 --rank 0 --stdout
but nothing happens...
So did i misunderstand its usage?
I quickly glanced at the code - i guess
orte_iof.pull(&target_proc, stream, 1)
is the heart of the matter. But i was unable to fnd where this
orte-iof struct fas actually defined. COUld you give me a hint?
