    Hi,

    First, please excuse me, because i dont speak english very well.

    I need your help, i have been tested a simple  MPI application. If i set a host´s list as argument  for example

    mpiexec.ex -hosts 2 a b  app.exe

    MPI enviroment is initialized fast but if i set

    mpiexec.ex -hosts 2 b a  app.exe

    is initialized so slow :-/, this take long time.

    Can you help me?

    The two commandline seems the same to me (You swapped a and b). Can you double check your questions?

    They are different in the host order "a b" " b a". 

    My problem is with some servers, Do i need to make something to the servers for MPI runs successfully? I added firewall rules.

    Thank you

    Hi Berny7,

    Have you been able to resolve this issue? If not, I would like to get some more information so I can try to reproduce this.

    a) Is mpiexec running on host a or host b (or in a different host altogether)?

    b) What is the output of ipconfig on host a and host b (and if mpiexec is running on a different host, I would like to have the ipconfig output of that host as well)?

    c) Does the same problem happens when you replace app.exe with "hostname"?

    Thanks
