Checking out my AP 7 tasks I noticed I'm finishing most in the 2000-3400 second range which seems pretty good. I'm some how beating out faster video cards with my 750TI and driver 337.88 but my CPU usage is much higher. http://setiathome.berkeley.edu/workunit.php?wuid=1617072555 Driver 344.11 seems common on the machines I'm beating.. Anyone actually tested that driver on AP v7 vs other drivers? Might be nothing, I am ready bed and might be looking at stuff wrong:) Any thoughts on my CPU usage? In my app_config I'm running .50 GPU and 1 CPU. The GPU's seem happy, I run quad 750TI and all stay in the 95-99% usage range.. Often hanging steady at 99.. |

You could look at using a commandline to decrease your CPU usage. Might increase the time to complete by 1-2 minutes. I use the following for my 750s -use_sleep -unroll 12 -ffa_block 8192 -ffa_block_fetch 4096 -tune 1 64 4 1 -hp You know where to install this at? Just asking, some people are don't use them but I've seen it help with the CPU utilization. Zalster Edit.. LOL That's my machine you partnered with. It only seems like yours is faster. I'm running 3 APs at a time on each of my cards so that is why the time looks longer. If I only ran 1 or 2 AP per card then the times would be closer. |

Nice machine:) Planning to play with some settings next time I'm off.. Been using a conservative -unroll 4 -ffa_block 2048 -ffa_block_fetch 1024 which seems to work fine. Want to try and do some testing with -cpu_lock and learn more about -use_sleep and -tune.. Someone really needs to write a nice seti for dummies guide:) Also want to test against different vid drivers.. Long ago I ran a GTX260 and found a nice boost using the old 266 drivers vs anything else.. Maybe I can find another sweet spot for the 750's.. |

The file is called ap_cmdline_win_x86_SSE2_OpenCL_NV.txt. add this -use_sleep -unroll 12 -ffa_block 8192 -ffa_block_fetch 4096 -tune 1 64 4 1 -tune 2 64 4 1. Tuning also kernel 2 makes more sense with this app. With each crime and every kindness we birth our future. |

Nice machine:) I did that already. Just read the readme. With each crime and every kindness we birth our future. |

The file is called ap_cmdline_win_x86_SSE2_OpenCL_NV.txt. So Mike, I should add this section then to my current Crunchers? That's new. Zule, Mike is the Guru to end all Guru on this. Trust what he says |

The file is called ap_cmdline_win_x86_SSE2_OpenCL_NV.txt. Yes. If you really want to speed up processing use -oclfft_plan as well. With each crime and every kindness we birth our future. |

Dont use any other values than i suggested in the read me for your card. I would prefer to continue this in the AP V7 thread. So everybody can follow this. If any question arises please ask. With each crime and every kindness we birth our future. |

Nice machine:) Maybe I'm missing something, but where's the readme? David Sitting on my butt while others boldly go, Waiting for a message from a small furry creature from Alpha Centauri. |

add this I wonder what will happen if the user copy the line as it is - with the dot at the end. Will this be accepted by the app or ... all tasks will fail? Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |
