Hi everyone !
I have to submit you a question,
I write a little code that does and MPI_Comm_spawn_multiple on a specific
set of node.
The node where to run on are specified using the "host" attribute of the
That attribute is filled with the string get from MPI_Get_processor_name.
Is this the correct way of working ?
I have a strange behavior when I use alias in the /etc/hosts file.
(I run jobs in a linux cluster, with CentOS 5).
If I use the alias in the hostfile the spawn process throws me an error;
instead the spawning process (run with the same hostfile) runs correctly.
It seems that is necessary, when using the spawn function with INFO object,
to run the spawning process with a hostfile filled with the "real" and
Or I have to use a different function to get the host name?
Thank you very much,
