Ah, don't worry. You must be on a power PC Mac instead of an Intel one, and the mismatch is simply in the endianness of the data. I just failed to account for the possibility of a Big Endian chip in the tests. So the failure is just in my test, your setup is OK. Sorry about that! Cheers, f

OK, this one you do need to fix. I'm attaching below the instructions on how to fix this... I'll be offline for a few hours, but let us know if you have any problems, I should be back in the evening. Cheers, f ar tutorial attendees, here are some notes regarding the tutorial requirements. I am sending this to all of you, though some of it may only apply to those attending the advanced track. - If you had troubles with the testing scripts, please note that I've fixed a few small issues. The current versions are (intro, advanced and pycuda-specific): https://cirl.berkeley.edu/fperez/tmp/intro_tut_checklist.py https://cirl.berkeley.edu/fperez/tmp/adv_tut_checklist.py https://cirl.berkeley.edu/fperez/tmp/pycuda_tut_checklist.py - For those of you on OSX, you may need to install Apple's XCode to get a working compiler on your system. XCode is free to download, but it's a very large download and you do need to register in their developer site to access the file. - For those of you using the Enthought Python Distribution (EPD henceforth), and attending the advanced tutorial track, you may need to manually add updated versions of Cython and Sympy, as those included by default are a bit old to demo all the features the speakers want to cover. Below are the instructions for this (if you are attending the introductory tutorials, the default EPD install is sufficient). - If you have a laptop with a CUDA-capable GPU, and you install the necessary requirements, you'll be able to follow the interactive parts of the tutorial. The tutorials page has links to all necessary prerequisites: http://conference.scipy.org/advanced_tutorials ================================================================ Instructions for an EPD-based setup for the advanced tutorials ================================================================ The current version of EPD has most of what you need, except for updated SymPy and Cython. 1. Install sympy 0.6.5, available at: - Source: http://sympy.googlecode.com/files/sympy-0.6.5.tar.gz - Windows installer: http://sympy.googlecode.com/files/sympy-0.6.5.win32.exe 2. Install Cython 0.11.2. On OSX you can do a source build, for Windows, binary installers are available: - Source: http://cython.org/Cython-0.11.2.tar.gz - Windows installer: https://cirl.berkeley.edu/fperez/tmp/Cython-0.11.2.win32-py2.5.exe 3. Then, edit the easy-install.pth file for EPD, located at: - Windows: c:/Python25/Lib/site-packages/easy-install.pth - OSX: /Library/Frameworks/Python.framework/Versions/4.3.0/lib/python2.5/site-packages/easy-install.pth Comment out the lines that read: ./cython-0.9.8.1.1n1-py2.5-win32.egg ./sympy-0.6.2n2-py2.5.egg By prepending a # mark at the beginning. 4. At this point, the advanced tutorials checklist script: https://cirl.berkeley.edu/fperez/tmp/adv_tut_checklist.py should run to completion without errors, let us know otherwise.
