Usually both VisIt and ParaView require to use the same version between the local client and the remote host, please try to stick to that to avoid having incompatibility issues, which might result in potential problems during the connections.īoth, VisIt and ParaView, allow for batch processing using scripting in different languages. Salloc -ntasks=N*40 -nodes=N -time=1:00:00 module load NiaEnv/2019b paraview-offscreen/5.9.1 either submit a job script or request a job using Open a file in ParaView (it will point you to the remote filesystem) and visualize it as usual.įor performing parallel rendering using multiple CPUs, pvserver should be run using mpiexec, ie.The first terminal window that read Accepting connection. Once the remote server is added to the configuration, simply select the server from the list and click Connect.Then click Configure, select Manual and click Save. You will need to point ParaView to your local port 11111, so you can do something like Start ParaView on your local computer, go to "File -> Connect" and click on 'Add Server'.This will establish a tunnel mapping the port 11111 in your computer ( localhost) to the port 11111 on the Niagara's compute node, niaXYZW, where the ParaView server will be waiting for connections. Open a new terminal without closing your debugjob, and ssh into Niagara using the following command,.Now, you have to wait a few seconds for the server to be ready to accept client connections.Ĭonnection URL: cs://:11111Īccepting connection(s): :11111.Note: if using the module paraview-offscreen/5.6.0 run pvserver with the -mesa-swr-avx2 flag as it has been reported to offer faster software rendering using the OpenSWR library. Module load NiaEnv/2019b paraview-offscreen/5.9.1 After getting a compute node, let's say niaXYZW, load the ParaView "offscreen" module and start a ParaView server,.Launch an interactive job (debugjob) on Niagara,.Similarly to VisIt you will need to start a debugjob in order to use a compute node to files and compute resources. In order to be able to use VisIt's parallel rendering capabilities, the following command must be issued after loading the corresponding VisIt module:Įxport LD_LIBRARY_PATH=$/2.13.1/linux-x86_64/lib run your favourite visualization program, eg.This will connect you to a node, let's say for the argument "niaXYZW" ssh into with the -X/-Y flag for X-forwarding.Runtime is limited on the login nodes, so you will need to request a testing job in order to have more time for exploring and visualizing your data.Īdditionally by doing so, you will have access to the 40 cores of each of the nodes requested.įor performing an interactive visualization session in this way please follow these steps: Notice that Niagara does not have specialized nodes nor specially designated hardware for visualization, so if you want to perform interactive visualization or exploration of your data you will need to submit an interactive job (debug job, see ]).įor the same reason you won't be able to request or use GPUs for rendering as there are none! Notice that for using ParaView you need to explicitly specify one of the mesa flags in order to avoid trying to use openGL, i.e.,Īfter loading the paraview module, use the following command: The NiaEnv/ 2018a environment additionally has modules for VisIt (2.13.1) and ParaView (5.5.0, and 5.6.0 for offscreen rendering only). We have recent versions of the open source visualization suites installed on Niagara: VMD (1.9.4) is available as a module in the default NiaEnv/ 2019b environment. 4.2 ParaView Client-Server Configuration.4 Remote Visualization - Client-Server Mode.
