< 2 Test Cases >

Case 1: Running 3D Model on single node
Case 2: Running 3D Model on GPFS

Case1.1 Access Once

PATH: /home/rock/3D_model
Tool: IvIsee 3.3.RC_5
Using Model: master1260.stl (1.4GB)
Terminal1 Command: rock@gpfs-server:/home/rock/3D_model$ IvIsee master1260.stl (load_3D_model)
Terminal2 Command: rock@gpfs-server:~$ sudo dstat -g -m -t -d -D sda (monitoring)

Example:

---paging-- ------memory-usage----- ---time--- --dsk/sda--
__in_ _out_|_used _buff _cach _free|__epoch___|_read _writ
   0     0 | 208M   18M  622M 2179M|1212050149|  25M    0 
   0     0 | 214M   18M  647M 2149M|1212050150|  25M    0 
   0     0 | 221M   18M  676M 2112M|1212050151|  29M  144k  

Conclusion: It takes total 50 seconds hd times (R/W)

Case2.1 Access Once

PATH: /home/gpfs_mount
Tool: IvIsee 3.3.RC_5
Using Model: master1260.stl (1.4GB)
Terminal1 Command: rock@gpfs-server:/home/gpfs_mount$ IvIsee master1260.stl (load_3D_model)
Terminal2 Command: rock@gpfs-server:~$ sudo dstat -g -m -t -d -D sda -M gpfs -N eth2 (monitoring)

Example:

---paging-- ------memory-usage----- ---time--- --dsk/sda-- --gpfs-i/o-
__in_ _out_|_used _buff _cach _free|__epoch___|_read _writ|_read write
   0     0 | 206M   20M 2050M  752M|1212052121|   0     0 |2048k    0
   0     0 | 209M   20M 2050M  748M|1212052122|   0     0 |  14M    0
