If everything has set up correctly you should see a printout of the hostnames with the resources requested. You will then be presented with the launcher, make any necessary changes then click launch. Once you have your allocation, run the command fluent Include all the commands you would usually use in your slurm header here. Salloc: Waiting for resource configuration Salloc: job 10270935 has been allocated resources Salloc: job 10270935 queued and waiting for resources Will return salloc: Pending job allocation 10270935 If you only require a few CPUs for a short while you may run the fluent on the login node, otherwise use of an slurm interactive session is recommended.įor example. While it will always be more time and resource efficient using a slurm script as shown above, there are occasions where the GUI is required. #SBATCH -hint nomultithread # No hyperthreading #SBATCH -licenses aa_r:1 # One license token per CPU, less 16 This can be d one by using cat to make a file from a ' heredoc'.īelow is an example of this from a fluent script. It is of ten useful to create this journal file in your SLURM script (tidiness, submitting jobs programmatically, etc). Some ANSYS applications take a 'journal' text file as input.
Make sure you set preferences using the same version as in your script. License preferences are individually tracked by each version of ANSYS.
prefer_research_license prefer_teaching_license Note The license order can be changed in workbench under tools > license preferences (provided you have X11 forwarding set up), or by running either of the following (ANSYS module must be loaded first using module load ANSYS). If your job is greater than the node limit, not switching to the research license before submitting a job will cause the job to fail. Whether to use a teaching or research license must be set manually. One of these is required for each CPU over 16 when using a research license. Can be used on up to 16 CPUs, for every additional CPU over 16 you must request additional 'aa_r_hpc' licenses. This is the default license type, it can be used on up to 6 CPUs on models with less than 512k nodes
