=== Case1.1 Access Once ===
PATH: /home/rock/3D_model [[BR]]
Tool: IvIsee 3.3.RC_5 [[BR]]
Using Model: master1260.stl (1.4GB) [[BR]]
Terminal1 Command: rock@gpfs-server:/home/rock/3D_model$ IvIsee master1260.stl    (''load_3D_model'')[[BR]]
Terminal2 Command: rock@gpfs-server:~$ sudo dstat -g -m -t -d -D sda      (''monitoring'') [[BR]]
