Cluster Computing
Here we introduce you how to perform cluster performing and batch management of engine nodes.
Note:
(1) Before performing cluster computing on multiple computers, please make sure that each computer is connected to same LAN and can connect each other. Each machine has read and write permission to other computers.
(2) Get3D Mapper software contains two modules: Get3D Mapper (UI for user to operate) and Get3D Engine runs at background (algorithms for automatic modeling).
1 Download & Installation
First, download and install Get3D Mapper on each computer.
The Get3D Mapper installation process will automatically accompany the installation of Get3D Engine.
2 Login Account & Activate License
After finishing the installation,
(1) Open the Get3D Mapper software on each of the computers,
(2) Log in to your account and activate the licence to each computer.
For more details on license activation, refer to the section Newbie Guide > License Acquisition
3 Start Engine
Start the engine on all computers:
Click Setting>Engine Setting in the menu bar.
Then click Start Local Engine to access the Get3D Engine interface.
4 Create Project
After obtaining license and starting the engine on all computers.
Select a computer as the master computer and create project.
Please set the project path to a network path that can be accessed by other computers. Subsequent operations can be completed on the project of this master computer.
Note:
All operations except Collaborative Marking Ground Control Points can be performed only on the main project of the master computer:
Creation of the project;
Import of the images;
Positioning of the images;
Submission of the Relative Orientation;
Submission of the Absolute Orientation;
Submission of Reconstruction (generation of the 3D mesh model).
Similarly, mobilizing the computational power of each engine node, managing the start or pause of the engine nodes, etc., can be done from a single engine interface.
For more details on create project, refer to the section Newbie Guide > Create Project & Open Project
5 Set Job Queue Directory
After creating the project, set the job queue directory for project. Make sure the Job Queue Directory to be network path.
Note:
There are four paths in the cluster calculation that need to be network paths:
① 【Create & Open Project】 Project Path
② 【Job Queue Setting】 Job Queue Path (for both project and engine)
③ 【Import & Read Image】 Image Path
For more details on setting job queue, refer to the section Newbie Guide > Job Queue & Engine Setting
6 Import Image & Positioning
For more details on importing images and positioning, refer to the section Newbie Guide > Impot Image, Newbie Guide > Photo Positioning
7 Submit Job & Distribute Engine Nodes
Job submission:
After completing the image import and positioning, and correctly filling in the Camera Information (Sensor Size and Focal Length), click Submit AT.
Distribute Engine Nodes:
(1) Open the engine interface. In the Engine Information list, you can see the current state of the Engine (Waiting, Running, Stop).
(2) Select all engines, right click and select Modify Job Queue Directory. Set all the engines to the job queue path where the main project submits the job.
Once the job queue is set correctly, all engines will start running. You can view the number and status of the running engines either in the engine interface or in the engine monitoring panel of Get3D Mapper.
