Follow the steps below: 1.Copy Toread to nodes vxargs -a /home/tsinghua_wgd/wangguodong/experiment/1111/nodelist.txt scp /home/tsinghua_wgd/wangguodong/experiment/Toread.tar.gz {}:/home/tsinghua_wgd/Toread.tar.gz 2.Uncompress vxargs -a /home/tsinghua_wgd/wangguodong/experiment/1111/nodelist.txt ssh {} tar -zxvf /home/tsinghua_wgd/Toread.tar.gz 3.Startup vxargs -a /home/tsinghua_wgd/wangguodong/experiment/1111/nodelist.txt ssh {} /home/tsinghua_wgd/1111/startup.sh 4.Get NCs cd Toread python gethostnc.py if you want to get the information of pharos, use the following command vxargs -a /home/tsinghua_wgd/wangguodong/sandbox/nodelist.txt -t 30 -o vxargxResult/ ssh {} 'nohup sh /home/tsinghua_wgd/sandbox/evaluatePHAROS.sh' 5.Terminate vxargs -a /home/tsinghua_wgd/wangguodong/experiment/1111/nodelist.txt ssh {} /home/tsinghua_wgd/1111/terminate.sh NOTICE: 1.All the above should be done when you're in the same directory as this README 2.Make sure that all your nodes have twisted installed.
