Haozi, I re-ran your example with mpich 3.1.3 and saw the behavior you described in #2. The current mpich/master does not behave like this. Can you try a nightly tarball to confirm? http://www.mpich.org/static/downloads/nightly/master/mpich/ Ken On 02/02/2015 08:02 PM, haozi wrote:

Haozi,
I'm not sure I understand the issue you are seeing. Can you include output from this code that illustrates the issue? I tried running with strings both less than and greater than 7 characters with no issue. The port_name is the same length in all cases on my laptop.

Hi, guys. My example code is the attachment.
1. What is the naming convention of service_name ? The hydra_nameserver CAN'T accept those strings whose length is less than 7. What's the exact naming convention?
2. The length of port_name by MPI_Loopup_name is different with MPI_Publish_name! You can test my code.
With best regards. Haozi
