For a Win XP x64 system. v0.37 & v.38 have a check box for the cpu ss level. the processor in the system is a P4 3.8GHZ HT with SS2 support. The Lunitic x64 installer starts with SS3. Can I use the x64 SS3 Generic or must I install the x32 version and use the SS2 option? The x64 SS3 Generic seems to work. The cuda card is a GTX 550Ti and I will be moving up to a GTX 560 in a few days Delta-V |

If your CPU supports SSE3 then you probably want to use that, or the SSSE3 app if you support that. You can use the x86 or x64 application in a x64 OS. I haven't seen any advantage of one over the other on my systems. If you use CPUz it will tell you exactly what your CPU supports.

From a quick look at this, http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors, it would indicate all 3.8GHz P4's are SSE3 capable. |

In either x64 version installer Under Multibeam (CPU.....) one of the check boxes is "SSE3 (x64, generic)". There is no SSE2 option in the x64 installers only in the 32 bit version. I'm running the 64 bit version of Seti. I'll try the 32 bit optimized version of Lunatic with the Seti x64. Thanks Delta-V |

I'm running the 64 bit version of Seti. I'll try the 32 bit optimized version of Lunatic with the Seti x64. You are correct there is no SSE2 x64 application. Is there some reason you only want to use SSE2? Looking again at the installer GUI I see what you mean by the SSE3 x64 Generic application. That just means it isn't specifically optimized for Intel or AMD. Unlike the x86 SSE3 apps that are specific for Intel or AMD. My preferences for applications on that system would be: 1) SSE3 (x64 Generic) [From Lunatics_Win64_v0.38_setup.exe] 2) SSE3 (Intel) [From Lunatics_Win32_v0.38_setup.exe] 3) SSE2 [From Lunatics_Win32_v0.38_setup.exe] Since you are already using the SSE3 x64 app I don't see why you would want to change it.

The confusion over SSE2 & SSE3 arose because Boinc at start up claims that the processor in question only supports thru SSE2. CPUZ says it is SSE3 capable. I'll just keep running it as is unless a problem develops. Thanks Again Delta-V |

I'll just keep running it as is unless a problem develops. The "Processor features:" from BOINC should be ignored in favor of something more accurate like CPUz. If your CPU couldn't do SSE3 all of your CPU tasks could be ending in computation errors.

Only as sidenote: At Boinc-Startup, SSE3 is called PNI-> Prescott New Instructions. - Performance is not a simple linear function of the number of CPUs you throw at the problem. - |

I really don't want to know. :-o Cheers. |
