authpath = fullfile (a = pkg ("prefix"), "parallel-srp-data")
Copy server files to servers, authpath is assumed to be
"/home/test/octave/parallel-srp-data/", the same directory is assumed to
exist on the servers. From the system shell, do e.g.:
scp -r /home/test/octave/parallel-srp-data/server server1:/home/test/octave/parallel-srp-data/
scp -r /home/test/octave/parallel-srp-data/server server2:/home/test/octave/parallel-srp-data/
Start server at remote machines. From the system shell, do e.g.:
ssh server1 'octave --eval "pserver"'
ssh server2 'octave --eval "pserver"'
# From Octave prompt, connect the cluster.
conns = pconnect ({"server1", "server2"})
# And perform some parallel execution. Single function calls take 1
# second each.
results = netcellfun (conns, (x) {x, pause(1)}{:}, num2cell (1:30))
# Close network.
sclose (conns)
