hi,

is there a way to jump through ganglia and plant jobs? so the situation is: i have this cluster which consists of 5 nodes(ganglia). the cluster has Rocks OS installed on it. so what i would like to do now is to somehow execute a job on each and every node of the cluster, and i would like to make the whole process totally automatic, so i do not have to ssh through nodes and manually start the jobs on every node. my idea was to retrieve the names of all the nodes, and then through system function jump to that node and start the job on it. but this is not working


chomp(my $host = qx(hostname -s));
foreach (@$ganglia_name){
  system("ssh $_") unless ($_ eq $host);
  # run the job
}

the result i get is: logging the the node and exiting the program
