pycuda install help
by nhieu duong
hi,
ive been endlessly trying to install pycuda on a red hat dist. machine, but
to no avail. it would be much appreciated if i could get some help.
i am able to get past the configure part of the installation, but the when i
"make" , the problem occurs. here is my siteconf.py file
BOOST_INC_DIR = ['/usr/local/include/boost/']
BOOST_LIB_DIR = ['/usr/lib']
BOOST_COMPILER = 'gcc4.1.2'
BOOST_PYTHON_LIBNAME = ['boost_python']
BOOST_THREAD_LIBNAME = ['boost_thread']
CUDA_TRACE = False
CUDA_ROOT = '/usr/local/cuda/'
CUDA_ENABLE_GL = False
CUDADRV_LIB_DIR = ['/usr/lib']
CUDADRV_LIBNAME = ['cuda']
CXXFLAGS = ['-DBOOST_PYTHON_NO_PY_SIGNATURES']
LDFLAGS = []
i beleive i built boost with gcc version 4.1.2
the error im getting is.....
/usr/local/include/boost/type_traits/remove_const.hpp:61: instantiated
from ‘boost::remove_const<<unnamed>::pooled_host_allocation>’
/usr/local/include/boost/python/object/pointer_holder.hpp:127:
instantiated from ‘void* boost::python::objects::pointer_holder<Pointer,
Value>::holds(boost::python::type_info, bool) [with Pointer =
std::auto_ptr<<unnamed>::pooled_host_allocation>, Value =
<unnamed>::pooled_host_allocation]’
src/wrapper/mempool.cpp:278: instantiated from here
/usr/local/include/boost/type_traits/detail/cv_traits_impl.hpp:38: internal
compiler error: in make_rtl_for_nonlocal_decl, at cp/decl.c:5067
i only included the ends. if you want the entire thing let me know. but the
error seems to point to a gcc problem. ive read thru
your archives but doesnt seem to solve this problem
if someone could shed some light on this issue, i would very appreciate it.
thanks

ImportError: No module named _driver
by Riccardo Taormina
Hi everybody,
I am new on PyCuda. I just installed everything on Windows XP and, from the installation log, I think that I did it properly. However, I tried to run the test files provided with pycuda and I get this error
Traceback (most recent call last):
File "C:\PyCuda\test\test_gpuarray.py", line 2, in <module>
import pycuda.autoinit
File "C:\PyCuda\pycuda\autoinit.py", line 1, in <module>
import pycuda.driver as cuda
File "C:\PyCuda\pycuda\driver.py", line 1, in <module>
from _driver import *
ImportError: No module named _driver
how can I solve it?
thanks and sorry for the newbieness of this post

Ubuntu 9.10 installation issue
by Simone Mannori
Bonjour,
I'm using UBUNTU 9.10 64bit distro on a NVDIA based laptop (Sony F11).
CUDA 3.0 has been installed and woks perfectly.
I have tried to install "stable" pycuda-0.93.tar.gz using the instructions
available on your web site (including gcc downgrade) without success.
I have tried also to install "git" version
In both cases the error looks the same (see below for the details). I have
tried all the hints available on-line without success.
Where is the mistake ?
Do you suggest to concentrate on 0.93, git or whatever?
Do I need to use another distro? 10.04 is incompatible with NVDIA-CUDA
driver, so I have stepped back to 9.10 (suggested by NVIDIA).
I'm a really green on Python, so I'm feeling lost. Pycuda looks great. I'm
working on thermonuclear fusion simulation (www.iter.org) using custom MHD
code: Pycuda could simplify A LOT the development.
Thanks in advance for your help

Re: [PyCUDA] pycuda test failures
by Peter Schmidtke
Hey,
thanks, I came accross your post to the mailing list but I thought it was a different issue in the beginning.
Now the test_driver.py is running. Also my own testing things seem to run OK...however seen the imprecision issues with gpuarrays I suppose I'd better not use them on Fermis right now?

GPUArray slices in CUDA Kernels
by Bryan Catanzaro
Hi All -
I needed to slice a GPUArray and then pass the gpudata of the resulting slice to a CUDA kernel expecting a pointer.
The current slicing logic in pycuda.gpuarray.GPUArray calculates the gpudata of the slice as an integer, which causes problems if I try to pass it as a pointer to a CUDA Kernel, due to the type mismatch between int and pointer.
I've solved this problem for myself by changing a couple things:
1. Adding a constructor to cuda.hpp/device_allocation: device_allocation(CUdeviceptr devptr, bool valid). This allows me to create a device_allocation object which will not be freed upon destruction. Obviously, the resulting pointer from a slicing operation that constructs a view of a gpuarray should never be freed.
2. Changing the constructor on wrap_cudadrv.cpp/DeviceAllocation from py::no_init to py::init<CUdeviceptr, bool>(), which allows me to instantiate a DeviceAllocation object from within python. Andreas, I have the feeling you won't like exposing this, but it was a quick solution that worked for me.
3. Changing the way the new gpudata is calculated in pycuda.gpuarray.GPUArray.__getitem__(), to create an "invalid" DeviceAllocation object that will not be freed upon destruction:
gpudata=drv.DeviceAllocation(int(self.gpudata) + start*self.dtype.itemsize, False)
I've attached the patch, in case it's useful.

2 Patchs: npy_* type and Elementwise kernel call
by Frédéric Bastien
Hi,
I'm modifying Theano to allow it to use the code generated by pycuda.
While doing so I needed 2 modifications to pycuda.
1) elemwise1.patch: This modification allow to pass the block and grid
to the ElementwiseKernel generated fct. If not provided, it continue
as before.
2) tools1.patch: recognize the npy_[u]{int}[8,16,32,64] and
npy_float[32,64] data type.
Do you have any questions/comments about those patch?
I don't use the gpuarray class that are passed to the pycuda fct. I
modified mine to mimic its interface. While doing so, I saw that you
use the attribute size and mem_size that seam to always have the same
value? Is that true? If so, why both?
thanks

64-bit cuda 3.1 on mac?
by Art
Is it now possible to use 64-bit CUDA on Mac OS X 10.6 with pycuda?
With CUDA 3.1, I can build and run pycuda tests fine with a 32-bit python,
boost. The Nvidia SDK examples default to build as 32-bit and work. But
with a 64-bit python and boost, I can build, but almost all tests fail.
My siteconfig.py with macports python 2.6 and boost 1.42, pycuda from git,
and output of 'python test_driver.py' attached:
BOOST_INC_DIR = ['/opt/local/include']
BOOST_LIB_DIR = ['/opt/local/lib']
BOOST_COMPILER = 'gcc42'
BOOST_PYTHON_LIBNAME = ['boost_python-mt']
BOOST_THREAD_LIBNAME = ['boost_thread-mt']
CUDA_TRACE = False
CUDA_ROOT = '/usr/local/cuda/'
CUDA_ENABLE_GL = False
CUDADRV_LIB_DIR = []
CUDADRV_LIBNAME = ['cuda']
CXXFLAGS = []
LDFLAGS =

Fwd: installing/upgrading issue with siteconf.py, setup.py and 0.94rc
by Vince Fulco
CC:ed to list
Sure I've missed something but here goes:
1) compiler invocation line
>From the siteconf.py file: BOOST_COMPILER = 'gcc44'
2) all errors leading up to (and including) the first header-not-found error?:
as an attempted fix, tried 'git'-ing the submodules init/update and
received a new error still related to headers.

“the possibility does not necessarily lead to materialization”

installing/upgrading issue with siteconf.py, setup.py and 0.94rc
by Vince Fulco
Hey PyCuda Gang-
Doing a clean install of 0.94rc after a previously working 0.93, i.e.
wiped out all Pycuda site-packages in python 2.6 directory prior to
new install. 'make' raises errors related to not being able to find
the boost headers, i.e. '/usr/include/boost /boost/ python .hpp'. My
siteconf.py file indicates BOOST_INC_DIR = ['/usr/include/boost'] same
as before and posted previously to this list, changed gcc42 to gcc44
in BOOST_COMPILER and that is it for changes. setup.py file indicates
it attaches a subpath like so :
# BOOST_INC_DIR/boost/python.hpp
if 'BOOST_INC_DIR' in sc_vars:
verify_path (
description="Boost headers",
paths=sc_vars['BOOST_INC_DIR'],
subpaths=['/boost/'],
names=['python'],
extensions=['.hpp']
);
but I can't seem to find where the additional '/boost/' label is being
attached if at all as indicated in the error message when the setup.py path
search executes. And my boost library is one level up
@ '/usr/include/boost/python.hpp'. Tried removing the subpath line
completely then error repeats but with '/usr/include/python.hpp'
suggesting path is not being modified further.
Running on F12 with boost1.39.0, cuda 3.1, gcc4.4.4. TIA, Vince.

Conjugate Gradient
by Dave Reynolds
Hi,
I would like to make use of your sparse conjugate gradient solver to speed
up some python code I am working on, however I am having no end of trouble
getting it to work. Can somebody please explain to me exactly what I need to
do to get the conjugate gradient solver in pycuda working?
Regards
