//  the following paron command starts up P-GENESIS with 4 nodes
//    ("-parallel" indicates that all nodes are in the same zone, i.e.,
//     their simulation times are advanced synchronously)
//    ("-output hello.out" indicates that the output from all nodes (except
//     node 0) will be written to the file hello.out; the output from
//     node 0 always goes to the terminal)
