2010-09-24 18:32:50 +0100 | answered a question | Sage and CUDA Okay I found some time and build now a package for pycuda. (see Ticket #10010 for details) on Ticket #10009 I provide also a package for PyOpenCL which can also used with ATI cards as well. The PyCUDA package can be downloaded from: http://code.google.com/p/spkg-upload/downloads/detail?name=pycuda-0.94.1.spkg (direct link: http://spkg-upload.googlecode.com/files/pycuda-0.94.1.spkg ) Installation Notes: - Install CUDA on your machine: http://developer.nvidia.com/object/cu...
set the SAGE_CUDA variable in your shell with: `export SAGE_CUDA =/where/you/have/installed/cuda` (i wrote this in .bashrc) - install package. (Download it from the links above)
- IMPORTANT: After installation the setuptools package has to be reinstalled!! Because the installer uses the distributed egg package. This messes somehow with setuptools and will be removed after the installation. But this destroys setup tools!
- enjoy!
It works for me. Hope it's usefull! |

2010-09-16 19:35:02 +0100 | commented answer | Sage and CUDA Ah I thought that no one's interested in it, so I'm decided to start attempts to get it up and running! I already bought a new graphics card. I hope in the next weeks I will start to get it built on my sage. I will try to get PyOpenCl also running. If there's interest I can start a ticket on this! |

2010-09-08 05:53:39 +0100 | commented answer | linking libraries in cython Thanx that worked! Is then the last code line in this tutorial ( http://docs.cython.org/src/tutorial/external.html ) false, outdated or does sage handle this different? |

2010-09-07 19:22:49 +0100 | asked a question | linking libraries in cython Hi! I have the following problem: I want to link an extern library like for example -lm to cython. If I now write for example the following problem: I get the following errors: So now my questions: Why does this fail? Am I able to link labraries anyhow? Can I link external libraries into sage that are installed on my system but not in sage like fftw? Or have I to install them somehow into sage before using it? Thanx in Advance! Maldun |

2010-09-07 11:04:13 +0100 | asked a question | Sage and CUDA Hi there! Is it possible to use CUDA within Sage. I didn't find any good answers yet. Can it somehow be linked, or is it even possible to use PyCUDA? |

2010-08-26 12:12:06 +0100 | asked a question | Latest versions of numpy+scipy Hi, I want to use the latest versions of numpy and scipy in Sage, but they are not up-to-date yet. My question is now: is it possible for me just to build the packages and install them (I guess not, because updating seems to be a time intense procedure) If someone is working on the Issues for numpy 1.5b and scipy 0.8 can he give me some infos? (I only found tickets for 1.4 or 1.7.1 which aren't ready yet) I also would provide help, if there is something todo, like testing. If nobody is working on this perhaps I have to start the tickets myself... |

2010-08-24 19:23:47 +0100 | commented answer | problems with symbolic integration and then numerical evaluating that's an interesting behavior. Thanks for your quick response! |

2010-08-24 19:08:05 +0100 | asked a question | problems with symbolic integration and then numerical evaluating can anyone explain this: from approximation one know's that the legendre coefficients converge exponentially to zero and not to infinity! and indeed with mpmath I get a better answer: Is there an overhead happening, when I numerically evaluate large rationals or something??? Thanks in advance, maldun |
