We are working with CT scan source images to segment bone. High resolution segments are needed. Each source Cropped Volume is around 1400x600x300 px. Grow from seeds is our actual approach.
Actual configuration:
- Operating system: Win10
- Slicer version: 4.11.0-2019-11-15 r28624
- Graphic card: Nvidia GTX 1060 6G
- RAM: 48Gb DDR3 1333
- 2x Xeon E5 2670
- SATA 3 SSD 240Gb
Each segmentation made with Grow from seeds takes around 10 min. Any paint tast to improve/fix segments takes around a minute so autoupdate is not very usable. Other edit segment tools are affected. Margin Tool - Grow is a full night task, for example.
Checking system monitor, we saw some interesting items:
- Just one core is 100%, the others are most 0%
- RAM is almost full
- Main thread is almost blocked.
Questions:
- How can we improve/change hardware for ideal configuration?
- Have CUDA drivers any role in this task? Which is best Nvidia Driver?
- Any application setting change could improve computation times?
Thanks on advance!
