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
slaveprocess
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.

Regards,
