Re: [mpich-discuss] Two problems about MPI_Publish_name/MPI_Loopup_name?

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.

Two problems about MPI_Publish_name/MPI_Loopup_name?
by haozi 28 Jan '15

28 Jan '15

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.

Yes, you can use these on different nodes as well, but you need to run the hydra_nameserver somewhere and tell mpiexec where the nameserver is using the -nameserver option. Use mpiexec -nameserver -help for more information. -- Pavan > On Jan 25, 2015, at 6:14 PM, haozi <yidanyiji(a)163.com> wrote: > > Also, I run server at node1, and run client at node2, and run client at node3, and ...

Using dynamic processes is not supported in MPICH for singleton init. Can you try running it with mpiexec? Also, note that you should be using MPI publish/lookup functions instead of writing to a file yourself. -- Pavan > On Jan 25, 2015, at 5:26 AM, haozi <yidanyiji(a)163.com> wrote: > > Thanks, Balaji. > > server_port_name.txt is built by the example, not by user. > > > At 2015-01-25 19:24:28, "Balaji, Pavan" <balaji(a)anl.gov> wrote: > > > >> On Jan 25, 2015, at 5:04 AM, haozi <yidanyiji(a)163.com> wrote: > >> Hello, Balaji. > >> > >> The example from OpenMPI is attached. > > > >server_port_name.txt is missing. > > > >-- > >Pavan Balaji ✉️ > >http://www.mcs.anl.gov/~balaji > > > >_______________________________________________ > >discuss mailing list discuss(a)mpich.org > >To manage subscription options or unsubscribe: > >https://lists.mpich.org/mailman/listinfo/discuss > > > > _______________________________________________ > discuss mailing list discuss(a)mpich.org > To manage subscription options or unsubscribe: > https://lists.mpich.org/mailman/listinfo/discuss -- Pavan Balaji ✉️ http://www.mcs.anl.gov/~balaji _______________________________________________ discuss mailing list discuss(a)mpich.org To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
