Fwd: Re: square, naca results
by Islam El Salawi
Hallo Andreas,
thanks for your fast respond. First of all I still receive
unsatisfactionary results, no matter if I watch them with paraview or
visit(axial velocity doesn't become null at the noslip boundary). What
about the warnings I get(I sent to you last time)? Are they supposed to
appear by running the square.py or naca.py example?
Secondly, trying to run hedge with cuda by writing out silo, I get an
error:
Traceback (most recent call last):

PyCUDA ERROR: The context stack was not empty upon module cleanup.
-------------------------------------------------------------------
A context was still active when the context stack was being
cleaned up. At this point in our execution, CUDA may already
have been deinitialized, so there is no way we can finish
cleanly. The program will be aborted now.
Use Context.pop() to avoid this problem.
-------------------------------------------------------------------
Aborted
And my .aksetup-default.py looks like:
#BOOST_INC_DIR = ['${HOME}/pool/include/']
BOOST_INC_DIR = ['/usr/include']
#BOOST_LIB_DIR = ['${HOME}/pool/lib']
BOOST_LIB_DIR = ['/usr/lib']
BOOST_BINDINGS_INC_DIR = ['${HOME}/pool/include/boost-numeric-bindings/']
BOOST_COMPILER = 'gcc44'
# WITH_SPARSE_WRAPPERS = True
BOOST_PYTHON_LIBNAME=["boost_python"]
BOOST_THREAD_LIBNAME=["boost_thread"]
SILO_INC_DIR = ['${HOME}/pool/include']
SILO_LIB_DIR = ['${HOME}/pool/lib']
If I change BOOST_INC_DIR and type in /usr/include/boost instead, I receive
the same error message. This problem is already posted in the pycuda
mailing list, though it couldn't help me out solve my problem. Maybe you
have an idea? Is there any trick to compile silo? I followed the
instructions introduced on scicomp. If you need any more information, just
give me a sign.
Regards,
Islam

Attribute Error on Staging: 'int' object has no attribute 'shape'
by Daniel Gempesaw
Hi,
I'm encountering a strange error on the staging branch of hedge. I created a
new virtualenv with distribute and no-site-packages and made a new clean
install according to the wiki instructions in case it was something strange
on my side, and I got the same error again. Checking out my local copy of
the master branch and doing setup.py install makes the error go away.
Traceback (most recent call last):

*AttributeError: 'int' object has no attribute 'shape'*
Is this error message familiar to anyone? I guess if no one recognizes the
error I'll try to checkout older commits of staging until I find one that
works.
Thanks!
