Re: [Hedge] LBM-DG

Andreas,
I hope you had a pleasant summer. I apologize for not keeping touch since
our last meeting. I have been at the Oak Ridge National Lab in Tennessee on
a summer Internship. I am now back in NYC. Unfortunately, my computer
crashed over the summer and I had to reformat my hard drive. That said, I
need to re-install hedge. I am going to follow the installation
instructions on the HEDGE website. I have been getting familiar with using
a UNIX shell so I hope the installation will NOT be like pulling teeth - as
you witnessed last time.
Speak to you soon.
Best,
Saumil

Running Examples with CUDA
by Tubbs, Kevin
Hi,
I've installed hedge with pycuda. I got the Install OK message after ./repotool start-over. I can run examples on CPU, but when I try to run on CUDA with "-f cuda". I get the follow error:
/src/hedge/examples/advection$ python advection.py -f cuda
Traceback (most recent call last):
File "advection.py", line 164, in <module>
main()
File "advection.py", line 77, in main
discr = rcon.make_discretization(mesh_data, order=4)
File "/home/ktubbs/HEDGE/src/hedge/hedge/backends/__init__.py", line 125, in make_discretization
return self.discr_class(mesh_data, *args, **kwargs)
File "/home/ktubbs/HEDGE/src/hedge/hedge/backends/__init__.py", line 144, in discr_class
from hedge.backends.cuda import Discretization
File "/home/ktubbs/HEDGE/src/hedge/hedge/backends/cuda/__init__.py", line 30, in <module>
import pycuda.gpuarray as gpuarray

ImportError: No module named compyte.array

Paul and I tracked down a leak in PyCUDA. If you were using GPU support,
then that might've been the source of the leak.
