Hi all,
I'm having difficulties passing data from the master to the children. I
haven't seen any complete tutorial, all the tutorial broadcast data where
I would like to send parts of my big tablechip list.
Everytime I run this, the last line always jams. I even tried to reduce
the number of rows in data to 10 and still doesn't work. I even tried to
do a remote.exec(ls()) and doesn't work.
Any tips?
#sending my function
mpi.bcast.Robj2slave(forSlaves)
#sending a message to all children so they wait for data
mpi.bcast.cmd(cmd={data = mpi.recv.Robj(mpi.any.source(),mpi.any.tag())})
# Now, send the data to the children
for( i in 1:nrow(adds)){
print(paste("sending part:",i))
data =
data.frame(tablechip[[1]][adds[i,1]:adds[i,2]],tablechip[[2]][adds[i,1]:adds[i,2]],tablechip[[3]][adds[i,1]:adds[i,2]])
mpi.isend.Robj(data,i,i)
}
#next line jams
results = mpi.remote.exec(forSlaves())
Thanks,
Remi
