Hi Jitrayut,

 

This is a problem with your MPI implementation. You should check the
documentation for the version of MPI you are using. If someone manages your
machine or queuing system then check with them to see what specific
requirements there are for running parallel jobs on your system.

 

You should also try some of the simple mpi examples that came with the mpi
implementation you are using since if you canít get these to run there will
be no chance of getting amber to run in parallel.

 

Note from the error message you may need to check that the line:

 

127.0.0.1 localhost.localdomain localhost

 

Exists in /etc/hosts

 

Although you should also carefully check the mpi documentation to make sure
there is nothing else you need to add.

 

Good luck,

Ross

what is my problem and how to solve this problem ?
