Hello everyone, this is my first post here. I work
with a Beowulf cluster, and i'm starting to
parallelize some aplications. And at this time i have
two questions:
1. When I pack data whit MPI_TYPE_STRUCT and send it
to the nodes, how i access the variables inside this
new type at the nodes? What i must do when the nodes
receive the message(via BCAST or MPI_RECV)?
2. When I make a MPI_SCATTER and the size of data is
not divisible by the numbers of nodes, what this
MPI_SCATTER do? exemple: sizedata=100; nodes=6;
local_n = sizedata/nodes. Whats happen if i call
MPI_SCATTER in this case?
Thanks
Mathias
