The Fluent application is now started with this CPU core count number, and the flag “-cnf=nodes” as follows. ~]$ cat nodes | wc -lĢ4 Mulit-node Step 7: Starting the Fluent Application The result is the total number of lines in the file, in this case, 24. The “cat” command outputs the file contents, which is then piped to the “wc” utility. Using the linux utility “wc -l” to count the number of lines that are in the file you created.
On Wendian to run the expands utiltiy ~]$ /sw/utility/local/expands $SLURM_NODELIST > nodes pre-Step 7b: CPU Core Count On Mio to run the expands utility ~]$ /opt/utility/expands $SLURM_NODELIST > nodes Then count the line to using “wc -l” to known the number of cpu core that are available in your Slurm job. The utility “expands” was written to produce this file on Mines HPC platforms using the Slurm nodelist variable as the argument and direct the output to a file. pre-Step 7: Preparing Fluent Node Connection Listįluent uses a file with a list of hostnames for each cpu that will run an MPI fluent process, one per line. Or using Slurm’s srun command: ~]$ srun -N2 -exclusive -pty bashĪnd continue through steps 2-6. In step 1, request an interactive session with multiple nodes. module load utility/standard/TurboVNC/2.2.4.If can also use MacOS terminal and Screen Sharing App that uses VNC protocols.įor newer version of Fluent use the direction at Ansys Remote Visualization Client Startup Guide in this example, a vnc client on your local computer will connect to a remote vnc server (vncserv.tech recipes :0) using port forwarding with an ssh connection to another remote host (sshd. using tunnels with ssh is a powerful method to access services on systems behind a firewall or that are otherwise inaccessible.
This tutorial uses Putty SSH tunnel settings for MobaXterm reference the other access guides for SSH Tunnel setup. Creating a putty ssh tunnel the urban penguin.
USE VNC THROUGH SSH TUNNEL INSTALL
Install putty or MobaXterm on windows, and TurboVNC (or your favorite VNC viewer. For Ansys Fluent version 19 and above consider using Ansys Remote Visualization Client Software Requirements Ansys Workbench and Ansys Electronics Desktop are also available. The application GUI Ansys Fluent version 18.2 is started as an example.
USE VNC THROUGH SSH TUNNEL FULL
This guide uses the vncserver TurboVNC installed on Mines HPC platform to access a full graphics environment in a Linux desktop.
