    Amint mondtam nem sokat kellet várni :) a válasz megjött:

    "Dear Andras,

    Thank you for your mail.

    The BG/L nodes have 2 FPU units.

    64-bit FPUs are a defacto standard for scientific calculations today
    because of performance and scalability.

    "An 80-bit FPU is typically slower or more expensive than either a 32-bit
    or a 64-bit FPU.
    Since some intermediate results are computed with 80-bit precision, and
    others with only 32-bit or 64-bit precision, answers depend on exactly how
    the code is written, what optimization level is selected, the compiler
    version, and other factors not under your control. Results tend to vary,
    making it harder to validate the software, and so forth."

    tehát csakis 64 bites az FPU...
