Note that all these salloc parameters need to be explicitly given, otherwise the script para581-multi.sh will not work Nine GB memory in total is allocated for the pvservers, and one GB for the client. The salloc example below allocates resources for one client and nine pvservers, each with two threads, so 20 CPUs are reserved. The script reserves one GB memory for the client, and the rest is divided between the pvservers. Ntasks is the number of pvservers plus one client, and cpus-per-task is the number of threads for each of these tasks, so the number of CPUs reserved is ntasks x cpus-per-task. Reservation is for the client and the pvservers combined. Resources should be reserved via salloc command. (After copying a script, check that is has execute permission - use chmod u+x to grant it.) The script needs no editing. The example script para5101-multi.sh, below, starts several pvservers and one client (front-end), and connects them. ParaView's D3-filter can be used to distribute work more evenly between the cores. You can check how much each pvserver is being used by opening Memory Inspector window in ParaView (file menu: View/Memory Inspector). Note that if most of the work is done by only one pvserver, using parallel setup can actually make ParaView run slower, due to extra time taken to parse data from different CPUs. The client connects to one of the pvservers, which communicates with the rest of the pvservers. Parallel mode - client using several servers (pvservers) and threadsįor demanding jobs, ParaView can be run in parallel mode: one client and many pvservers, each running on separate CPUs. ![]() Srun -ntasks=1 -cpus-per-task=5 -partition=small -time=01:00:00 -mem=32G -account= -x11=first -pty bashĪs previously, once directed to a compute node, load module and start ParaView. When resources become available, the session is directed to a compute node. You can use sinteractive -i command to reserve one CPU and up to 16 GB memory for your interactive session. Note that ParaView should not be run on the login node. Standalone ParaView needs no pvserver reservation. This mode is sufficient for basic visualization tasks and is a good starting point also for more complex tasks. The most straightforward way to use ParaView is to run it in standalone mode. ParaView uses a permissive BSD license that enables the broadest possible audience, including commercial organizations, to use the software, royalty free, for most purposes. There are many ways to run ParaView, to suit different needs. ParaView is designed to run parallel tasks, and consists of one client and one or several servers (pvservers). ![]() In this case, select Accelerated visualization instead of Desktop You can now also enable interactive visualization with GPU
