Hi Nolan, The (2D) test cases that ship with PyFR are all pathological on terms of their ability to assess performance since they are so small.
You should try using one of the bigger 3D cases from one of our recent papers (setup files should be available as supplementary material) Thanks for your interest in PyFR!

I changed the precision to 'single' in the .ini file, and the Couette flow took slightly longer than the double precision case (5:39 vs 5:43)! I don't really know what's going on right now so I'm going to start by testing my CUDA installation, pycuda, and pyfr, respectively to see what the issue is. Do you have any ideas off the top of your head? Considering that you could trade 4 Nvidia Tesla P100 cards for a Tesla Model 3 at current market values, I don't think there will be any just lying around at school. However, if I can get some of my cases working, the new graham cluster is equipped with a bunch of heterogeneous computing nodes with Tesla P100s.

Re: "weird command-line printout...", I run Visual Studio 2015 on Win7, and saw that sort of output when stepping under Visual Studio debugger. For normal runs, I get a neat console-mode "progress bar" by adding the following block near the end of pyfr/progress_bar.py: # Write the progress bar and pad the remaining columns if sys.platform == 'win32': # NN: for windows console sys.stdout.write('\b' * 80) sys.stdout.write('\r') sys.stdout.write(s) sys.stdout.flush() else: sys.stderr.write('\x1b[2K\x1b[G') sys.stderr.write(s) sys.stderr.flush() # Update the last render time self._last_wallt = wallt Nigel On Saturday, July 1, 2017 at 6:39:58 AM UTC+10, Nolan Dyck wrote: Hello PyFR community, -- You received this message because you are subscribed to the Google Groups "PyFR Mailing List" group.
