If your ParaView server gets killed when processing these data, you will need to increase the number of cores. a structured to unstructured dataset conversion will increase your memory footprint by ~3X) depending on your workflow, you may want to start this rendering with 32 cores or 64 cores. In addition, it is important to allocate some memory for filters and data processing (e.g. Since software rendering is CPU-intensive, we do not recommend allocating more than 4GB/core. a single timestep) would require at least 12 cores just to hold the data. For example, a 40GB dataset (that you load into memory at once, e.g. The easiest way to estimate the number of necessary cores is to look at the amount of memory that you think you will need for your rendering and divide it by ~3.5 GB/core. Due to additional complications with GPU rendering, we strongly recommend starting with CPU-only visualization, allocating as many cores as necessary to your rendering. On Cedar, Graham, Béluga and Narval, you can do client-server rendering on both CPUs (in software) and GPUs (hardware acceleration). Please use the tabs below to select the remote system.Ĭlient-server visualization on Cedar, Graham, Béluga and Narval For example, to use ParaView server version 5.10.0 on the cluster, you need client version 5.10.x on your computer. NOTE 2: ParaView requires the same major version on the local client and the remote host this prevents incompatibility that typically shows as a failed handshake when establishing the client-server connection. Experiment with the threshold to find a suitable value. If you set it to 0MB, all rendering will be remote including rotation, so you will really be using the cluster resources for everything, which is good for large data processing but not so good for interactivity. If you set it to default (20MB) or similar, small rendering will be done on your computer's GPU, the rotation with a mouse will be fast, but anything modestly intensive (under 20MB) will be shipped to your computer and (depending on your connection) visualization might be slow. NOTE 1: An important setting in ParaView's preferences is Render View -> Remote/Parallel Rendering Options -> Remote Render Threshold. 2 Remote VNC desktop on Graham VDI nodes.
