    Please recommend a 64-bit distribution

    Hi all,

    I need a 64-bit Linux distribution to help beta test TeraChem, a GPU-based quantum chemistry package. I have never personally used Linux, however, and I don't know anything about the available distributions. I was wondering if I could get some recommendations.

    My system specifications:

    CPU: Xeon W3520
    GPU: NVIDIA GTX 275
    Motherboard: GIGABYTE EX-58 UD5
    Current OS: Windows 7 64-bit

    I would not use Linux as my sole OS but would want to dual-partition (I think that is the term?). However, I think I would end up using the distribution for more than just running TeraChem. I may even become a convert!

    What am I looking for in a distribution? Ease of use, efficiency, 64-bit. What do I know how to do? I can build computers, code in C++, comfortably use a command line and tell you anything you'd like to know about chemistry (well, almost).

    Hopefully this is enough info about my knowledge and needs to allow for some good recommendations. Thank you and let me know if any more info is needed.

    They dont say, it wont work on other linuxes, but you will have the fewest problems with RedHat Enterprise 5.3 64bit, as this is the development platform.

    It is safe to use the newest version 5.4
    and also CentOS 5.4 64bit.
    CentOS is *almost* the same as redhat enterprise (it is built from the same sources) but lacks some redhat branding and the redhat commercial support.
    You must always face the curtain with a bow.

    Welcome to the forums, parisha!

    Ditto what he said... this would also be my recommendation if you don't want to purchase Red Hat Enterprise Linux

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    I would generally concur with the use of CentOS 5.4 x86_64. I am currently running that with an nVidia 8800GT GPU on a high-end workstation. There is nVidia support for the CUDA extensions and libraries on that system as well.
    Sometimes, real fast is almost as good as real time.

    Thanks for the recommendations. I have downloaded the 64-bit CentOS (5.4 x86_64) as well as 64-bit Ubuntu, onto another PC with an Intel i5-750 and NVIDIA 9800GTX. I am going to try out both OS's and see which one works best for my wants. I will report which I select and how they feel, as well as how they work for my HPC needs.
