Ansys HPC Support
ANSYS HPC Packs are a flexible way to license parallel processing capability. For single users who want the ability to run simulations on a workstation, a single ANSYS HPC Pack provides great value with increased throughput of up to 8 times. For users with access to larger HPC resources, multiple HPC Packs can be combined to enable parallel processing on hundreds or even thousands of processing cores. ANSYS HPC Packs offer virtually unlimited parallel processing for the biggest jobs, combined with the ability to run multiple jobs using everyday parallel capacity.
Ansys Job Submission:
- For Ansys there is no graphical user interface provided
- You must submit your job in batch mode using qsub
- Linux script is provided and you may change source file name and output file name
- You can change number of processors and number of nodes according to your need
- In your input.txt file that call model file from inside, you can add the following lines on the top
/BATCH
resume, modle.db
your script begins here
#!/bin/sh
#name the program, your default output error file are Test_ansys.oJobid
#and Test_ansys.eJobid
#PBS -N Test_ansys
#follwing 2 lines ensures that you'll be notified by email when your job is done
#PBS -M user_id@tigermail.auburn.edu
#PBS -m e
#you are asking for 1 node 16 processor each, 16 processor as a total for 50hrs
#after 50 hours your job will be killed
#PBS -l nodes=1:ppn=16,walltime=50:00:00
#your directory path that can be obtained by pwd
#PBS -d /home/your_directory_path/
#loading variables do not change this
export PATH=/export/apps/ansys_inc/v130/ansys/bin:$PATH
#writing mpd_nodes to boot mpd in these nodes and conf_file to select processors
`sort -u $PBS_NODEFILE > mpd_nodes`
#assignin nhosts variable to number of nodes
nhosts=`cat mpd_nodes | wc -l`
#generating conf_file to select processors
`sort $PBS_NODEFILE > conf_file`
proc=`cat conf_file | wc -l`
#printing initial timestamp

#printing which host performed computation

#executing ansys with 16 processor, < your input file that call model file inside from it >> your output file

#end time stamp

end of your script
- Create a directory using "mkdir testing"
- Go to that directory using "cd testing"
- Write a script file in vi editor similar to these
- Make sure it is executable by "chmod 744 file_name.sh"
- Submit the job using "qsub ./file_name.sh"
- Give a "showq" to see if your job is running
- You can terminate the session using "exit" but your job will be running and you can check back the results after 1-2 days whenever your job is done (you'll also be notified by email)
