Architecture of Remote Computing
In Remote Computing, four roles are defined as the followings: Client, Portal node, Head node, and Compute node.
Layout 1 (Generalized): All roles are located at different computers.
Layout 2: Portal & Head nodes are located at the same computer. In this layout, Portal & Head nodes are integrated as the Master node.
Layout 3: Portal, Head and Compute nodes are located at the same computer.
Layout 4 (Compact): All nodes are located at the same computer.
In the following section, layout 2 is used for reference, and the word “Master node” is used to indicate Head node plus portal node.
Installation of Remote Computing
The installation of master node is illustrated:
Step 1: Run Moldex3D Setup and choose Stand-alone (Node Locked) or Floating Client
Step 2: Select Moldex3D R15.0 (64-bit) and Parallel Computing Component (MasterNode)
Step 3: Create Moldex3D folder and working folder
Step 4: Create a limited user account and selected IP for parallel computing
Step 5: Input floating license server IP (or host name) and port number
Step 6: Click Install to begin the installation
Step 7: Complete installation and click Finish
Compute nodes are the machines that participates computing activities. They are controlled by the master node to perform computing/analyzing duties. When jobs are submitted to master node by users, the master node will assign compute nodes to perform job analyses. The master node itself will automatically participate in computing as a compute node only if there is no other compute node. Before installing compute node, please make sure that the parallel computing component (Master Node) is already installed on master node. The installation of compute nodes is illustrated as the followings.
Step 1: Run Moldex3D Setup and choose Licensing & Parallel Computing Components
Step 2: Select Parallel Computing Component (Computing Node)
Step 3: Choose the disk and the folder on the master node where acc.ini is located
Step 4: The firewall setting for Windows will be automatically configured
Step 5: Click Install to begin the installation
Step 6: Complete the installation by clicking Finish. Users can install another compute node by the same procedure from Step 1 to Step 7
Step 7: Start Job Scheduler on the master node. In the Nodes tab, make sure the Status of nodes participated in computing is shown as “Online”. Users can change the status of nodes to online by the Online button
