    See https://arxiv.org/html/2504.08009v1 . Looks quite interesting...

    The original "abs" page format has links to other papers
    by the same authors.

    https://arxiv.org/abs/2504.08009v1

    It is often worthwhile to check what else they have written
    but arxiv indexes on last name and first initial so
    watch out for authors with the same name. e.g.

    https://arxiv.org/search/cs?searchtype=author&query=Ozaki,+K

    I've looked for more information about this.

    Although it's an efficient way to perform some FP64 computations
    through the use of a resource that only supports FP8... it has the
    limitation of only working at its most efficient if one is working
    with square matrices.

    So it is still useful to have a computer with real FP64, even if this
    technique allows people doing scientific computations to bask in a
    subsidy from people doing AI work.
