New Revision: 15591
URL: http://svn.gna.org/viewcvs/relax?rev=15591&view=rev
Log:
Implemented the mpi4py processor fabric data_upload() method.
This currently sends the data out into the ether using an MPI.COMM_WORLD.send()
call with the
tag 10 which will be reserved for sending data into the data store. Somehow
this needs to be caught
and stored by the slaves.
