![]() ![]() It will wait for the connection, once connected execute the visualisation pipelines you create, and finally close itself once you disconnect. If all is well, ParaView should have written a message to the terminal indicating that it is waiting for a connection from the client on the given port. # mpiexec -np 8 pvserver -use-offscreen-rendering -server-port=44444 # mpdboot -totalnum=10 -file=/opt/mpich2/osu_ch3_mrail_vapi-gnu/share/nashi.hosts -mpd=/opt/mpich2/osu_ch3_mrail_vapi-gnu/bin/mpd -chkup Execute the following sequence of commands at the bash prompt, of course replace n04 with the values you used in the previous step. Now you will start the ParaView data server that has been configured for the infiniband network. Start the ParaView data server.Īt this point you should have a putty session open connected to nashi with an ssh tunnel established. Putty configure the tunnel from n001 to our workstation. Finally, click the Open button in the lower portion of the window, and log into nashi. In the future you may Load the named configuration. Navigate back to the Session configuration panel and save the configuration so you don't have to do this each time you wish to connect. Make note of your choices of each as they will be passed into ParaView when it is run. These port numbers can be anything and the hostname should be one of the compute nodes. ![]() The destination hostname:port pair specify what host relative to nashi the ParaView data server will run on, and the port it will use to connect back to the client. The source port is used by the ParaView client running on your workstation. For example set the source port to 11111, the destination to n001:44444 and click the Add button. We use this to avoid running on nashi's head node, or to connect to a an assigned node from a batch job. The destination also includes a hostname that can be used to tunnel into the cluster's private network. You will set the Source port and Destination ports to numbers of your choosing. To configure the ssh tunnel navigate to the Connection->Ssh->Tunnels configuration panel, as shown in the following figure. Here you will enter and later save the configuration for use next time. The following figure shows the Session configuration panel. We will use "putty" a freely available ssh implementation for Windows, however any ssh implementation should work fine. Clean up MPI process managers running on the cluster.Įstablishing the ssh tunnel between the workstation and the cluster is the first step in remote data visualization using ParaView.Launch a ParaView client on the workstation.Launch a ParaView data server using mpiexec on the cluster.Launch MPI process managers on the cluster.Craete an ssh tunnel to a specific compute node on the cluster using arbitrary ports.However, there is very likely a firewall between your workstation and the cluster that prevents use of most ports, and therefor you will have to establish an ssh tunnel that will pipe the information through the ssh port which is left open on most firewalls.įor this example we are going to ignore the batch system. ParaView's components connect to each other over sockets at an arbitrary port number that you will choose. This process will transmit data and commands from the client to the other server processes. The client only will connect to the first server process. In the case of remote interactive visualization you will run the client, which is where the user interface resides, on your workstation and the data server on the cluster. ParaView has three major components the client, the data server, and the render server. Introduction: ParaView in client/server mode. 3 Example 2: An interactive run through the batch system.2.3 Start and connect the ParaView client. ![]()
