My machine crunch currently MW@h WUs with the stock v1.00 CPU app. If I remember correct, MW@h results don't need wingmen for confirmation .. But, all CPU results of my machine need 2 wingman for confirmation. Is the stock CPU app buggy? Are optimized CPU apps available which use the CPU instructions? Or use the stock CPU app these already? Thanks. |

If I remember correct, MW@h results don't need wingmen for confirmation .. Not always, but they increased the sensitivity of the thing that decides when to send out the WU once more, so many WUs are send to 2-3 computers. Also IIRC at the beginning a new computer/app is tested a bit more than usuall untill it has shown, that it's working OK, so eventually that will be less after some validated results. Are optimized CPU apps available which use the CPU instructions? They are little bit optimized, they have different paths for different CPUs, yours is for example "Using SSE4.1 path" as stated in the std_err. But of course they are not as good as the old Gipsel apps, for my AthlonXP they needed just 2/3 ot the time the stock app needed. |

So I understood it correct, that currently are no optimized CPU apps available? Currently are the stock CPU apps the only solution? Is someone working at optimized CPU apps? Are MW@h *cuda23* apps (maybe 3rd party) available? (The stock OpenCL app need at least NVIDIA driver 266.58, if I remember correct. But, I need to sticky with NVIDIA driver 190.38) Thanks. |

So I understood it correct, that currently are no optimized CPU apps available? Yes. Is someone working at optimized CPU apps? No idea, I didn't heard anything about it so far. Are MW@h *cuda23* apps (maybe 3rd party) available? Hmm... haven't seen any so far, but OTOH I didn't search for anything like that since I don't have any usable nVidia cards. Maybe some nVidia users can tell you more. |
