I followed the steps on page http://mpjexpress.org/docs/guides/linuxguide.pdf, and I can start daemons on all machines. If I just run program on single server, it runs successfully
[ip1,master] MPJ Daemon started successfully with process id: xxx
[ip2,node] MPJ Daemon started successfully with process id: xxx
But when I use command mpjrun.sh -np 2 -dev niodev HelloWorld, it shows java.net.ConnectException: Connection refused and Multi-threaded starter: exceptionnull, but I can Ping this IP successfully.
Is anything wrong? Thanks for your comments.
