Q: (Version 1.0.0 ) I have N nodes in my nodes list but I cannot use all the nodes.
A: In version 1.0.0 of the mpi API, the node list declared in the file /ldas_outgoing/mpiAPI/LDASmpi.rsc must be declared in such a way that ALL node names first appear once before ANY node name is declared a second time. For example: This will NOT WORK:
set ::NODENAMES [ list node0 node0 node1 node1 node2 node2 ]
This WILL WORK:
set ::NODENAMES [ list node0 node1 node2 node1 node0 node2 ]
This error is generated when the list is declared incorrectly:
mpirun: cannot start /ldas/bin/wrapperAPI on n8: invalid node
Where 'n8' can have any integer value following the 'n'.
