Re: [Opaltoolkit-users] problem running parallel jobs with MPI

[Sriram K. <sr...@sd...>]

Hi Malcolm,

The AppService is the generic interface on the server-side. To give  
you a more specific answer, we would need to know what language/client  
you are using. All Java documentation can be found here: http://www.nbcr.net/software/opal/docs/2.0/index.html 
, and all Python docs are here: http://www.nbcr.net/software/opal/docs/2.0/opal-py-index.html 
.

Thanks,
Sriram
