Subject: Re: [OMPI devel] OpenMPI on Cell BE
From: George Bosilca (bosilca_at_[hidden])

At UTK we had a cluster of PS3. We wrote a documentation on how to use
the PS3 cluster, including how to configure and install Open MPI there
(there is a configuration file in the platform directory). You can use
the following link http://www.netlib.org/utk/people/JackDongarra/PAPERS/scop3.pdf

However, the application running on the PPE is in charge of starting
whatever you want on the SPE. In other words, Open MPI is unable to
start MPI processes on the SPE.
