    Dear FLUKA users,

    I was able to answer my own question, but thought it might be useful to
    others.

    I have successfully linked FLUKA on an opteron machine, and all that was
    required was to add the compiler flag -m32 to the lfluka script. This flag
    forces the use of the 32bit libraries instead of the default 64bit
    libraries.

    Kerry

    Dear FLUKA users,

    Has anyone tried to link FLUKA on an AMD-Opteron machine running Red Hat
    Enterprise linux?
    I can compile on a P4 machine running RHEL3, but get a compatability
    error on the Opteron. I was under the impression that there should be
    no compatability problems. I am thinking maybe the libraries I need are
    not used by the g77 compiler by default on the Opteron system.

    Any help is appreciated.

    Thanks
    Kerry

    Hi,

    I would like to run different FLUKA runs on multiple
    processors/machines,
    but want to avoid the overlapping of random seed sequences. I saw the
    following in the fluka-discuss archive.

    Alfredo responded to this message saying that this mechanism was not in
    place yet but would be there in the next release. Since this was almost
    3
    years ago I assume this mechanism exists now in the April 2004 release,
    is
    that correct?

    If I understand what Alberto said in his mail, I should be able to put
    in
    any number less than 9.E8 in what(2) of RANDOMIZE and not have to worry
    about repeating random sequences for different runs as long as I use
    different values in what(2) of RANDOMIZE. Is that correct?

    Thanks
    Kerry
