single_node($bin);Prepares and returns the command to run as string for a single host (localhost). bin is required. need_interpreter boolean will tell if the bin is actually a source code where needs invoke _python_ interpreter.
all_nodes($bin);Prepares and returns the command to run as string for all the nodes in the cluster. bin is required. need_interpreter boolean will tell if the bin is actually a source code where needs invoke _python_ interpreter. TODO: improve the identification of the bin
slave_nodes($bin);Prepares and returns the command to run as string for assigning only the compute nodes of the cluster. bin is required. need_interpreter boolean will tell if the bin is actually a source code where needs invoke _python_ interpreter. TODO: improve the identification of the bin
n_nodes($bin, $n);Prepares and returns the command to run as string without pass --host variable. Instead defines the number of nodes which the code should run on. bin is required. n is required need_interpreter boolean will tell if the bin is actually a source code where needs invoke _python_ interpreter. TODO: improve the identification of the bin
