Subject: Re: [OMPI users] Help: OpenMPI Compilation in Raspberry Pi
From: George Bosilca (bosilca_at_[hidden])
Date: 2013-01-21 06:50:01


Great, I pushed everything upstream:
 - trunk (r27882)
 - prepared a patch for the 1.6 (https://svn.open-mpi.org/trac/ompi/ticket/3469)
 - requested a CMR for the 1.7 (https://svn.open-mpi.org/trac/ompi/ticket/3470)

Thanks for your help,
  George.
