Hi 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?
