some little news, now i'm *authorised to post this:
1, MaxxPI² MultiCore ( Pre Alpha
screen with an Q6600 at 4100mhz, first 1core below 4cores (scaling)
will support 2,3,4 and 8cores (for now), calculate up to 256M (for now)
chudnovsky used, incl. splitting.
put about >78%! constant load (PMU),
on *all cores, so be carefull. has no CPU-specific optimizations for any
CPU manufaturers. uses mmx/sse
main problem was, load balancing (especially with chudnovsky) and not
to prefer any CPU manufacturer.
this both slow down the calc. speed, but i think at CPU/PC -benchmarking,
this doesn't matter at all, because comparability is the key.
optimized for an major CPU manufacturer a performance
gain from +12% to +18% is possible.
@allegratorial, i know it's important for you:
MaxxPI² MultiCore ( Pre Alpha
256M, with i7 at 4ghz, with 4cores/4threads (not 8): 473sec.
256M, same machine, with 4cores/4threads (not 8): QPI: 402sec.
256M, same machine, with 4cores/??threads, (not 8??): y-chruncher: 229sec.
2, much more intressing I think, is this:
this will released soon
