Subject: [OMPI users] Spawning processes through MPI::Intracomm::Spawn_multiple
From: vipin kumar (vipinkumar41_at_[hidden])

Hi all,

 I am trying to spawn dynamically processes in remote as well as local
machine using MPI::Intracomm::Spawn_multiple. I am using MPI::Info object to
tell where to launch processes using "host" key and "<ip_address>" as its
value but but I am getting the error

There are no allocated resources for the application
that match the requested mapping:

Verify that you have mapped the allocated resources properly using the
--host or --hostfile specification.

I tried with "<hostname>" too.
but its not working.

It works fine if I give the value "localhost" to "host:" key. It launches
successfully processes in local machine.

any help will be greatly appreciated.
