You can ignore this. This just means that the memory pool tests allocate more
memory than is on your card. I'll fix this eventually, promise. :)

Hello,
at the end of the install :
$ cd PyCuda-VERSION/test
$ python test_driver.py
need a gcc on the node with the GPU ?
Here, we have a cluster with login node (on wich i've compil+link) and
executions nodes with GPU (but whithout compiler).
Thank you.

Hello,
i try to install Pycuda on a host with python 2.4.
All is good (boost, numpy), until i fall on a problem during the make of
pycuda. There's a test on the version of python (for version >= 2.5 ...), and
that break my compil :
src/cpp/cuda.hpp: In member function ‘void
cuda::memcpy_2d::set_src_host(boost::python::api::object)’:
src/cpp/cuda.hpp:942: error: ‘Py_ssize_t’ was not declared in this scope
src/cpp/cuda.hpp:942: error: expected `;' before ‘len’
src/cpp/cuda.hpp:942: error: ‘len’ was not declared in this scope
Any idea ?

Maybe I've just caught the repo in the midst of changes, but in trying
to run the examples/plot_random_data.py, I get:
$ python plot_random_data.py

Unrelated, and off-topic, does anyone happen to use git inside

Hi Jyh-Shyong,
first off, for your own benefit and that of "posterity", please keep the list
cc'd on your replies.

Weird. Quick request before we move into debugging mode: Please do 'rm -Rf
build' in the PyCuda directory, then reinstall and try again. Distutils is not
exactly good at figuring out when it needs to recompile stuff.

Hi,
I just installed pycuda-0.90.2 on my computer and I got the following
error message when I ran the program test_drive.py:
python test_drive.py
Traceback (most recent call last):
File "test_driver.py", line 2, in <module>

The OS is OpenSuSE 11.0, and Cuda 2.1 Beta is installed.
Do I miss something?
Thanks.

Greetings,
I'm trying to build pycuda for my first time and have hit a snag
already. Thought I'd ask this list while I go off and search for
solutions on my own also. The first obvious problem is that my
'ctags' doesn't have a "-R" option. I'm on OSX 10.5.5 and using gcc
4.2 (although the system python 2.5.1 was built using 4.0.1, fwiw).
I attempted/get the following:
$ ./configure --boost-inc-dir=/usr/local/include/boost-1_37 --cuda-
root=/usr/local/cuda
$ make
ctags -R src || true
ctags: illegal option -- R

Hello,
I noticed in the pycuda documentation that it is possible to pass
command-line parameters to nvcc for compilation of source modules. My
question is whether it is possible to use the -deviceemu flag to have a
source module run in emulation mode? If so, what would be the syntax for
the source module, maybe using this as an example:
mod = drv.SourceModule("""
__global__ void multiply_them(float *dest, float *a, float *b)
{
const int i = threadIdx.x;
dest[i] = a[i] * b[i];
}
""")

Thanks very much. boost had indeed linked against the default Leopard
python version (2.5.1) instead of the later update I have been using
(2.5.2). Truth is, I had forgotten there was an "original" version and
that's what threw me off (/System/Library/Frameworks vs
/Library/Frameworks for the newer stuff from python.org). It shouldn't
have mattered but it did. Works now. Thanks again.
