    I just started a new WU, and before it started it had to download core version 79, which it calls "Folding@Home Double Gromacs Core". Anyone done one of these units before? Any performance/speed/points issues?

    EDIT: now working on protein p971_fkcomp_dock

    Yes, I've had one months ago, although the latest is dated February 19th. It's a double-precision core for more precise work. Apparently, it doesn't use AltiVec for that part as AltiVec can't do double-precision numbers.

    If I remember, it takes longer for them to run but that would make sense since they're using it for precision. It should handle those protein WUs that end with simulation instability because of a lack of space between elements.

    That would explain it all right. Two out of my last 7 units (same protein) ended with simulation instability, first at 41%, then at 95%. Although it's doing a completely different protein now.
