Here is my current app file, should I just copy the other app file into it. I did take notice that suggested file has SSE2 in it VS SSSE3. Here is the app file with the changes, good thing you mention there were 2 instances of the <cmdline>, I'm sure I'd have not noticed it. <app_info> - <app> <name>setiathome_enhanced</name> </app> - <file_info> <name>AK_v8b2_win_SSSE3x.exe</name> <executable /> </file_info> - <app_version> <app_name>setiathome_enhanced</app_name> <version_num>603</version_num> - <file_ref> <file_name>AK_v8b2_win_SSSE3x.exe</file_name> <main_program /> </file_ref> </app_version> - <app> <name>astropulse_v505</name> </app> - <file_info> <name>ap_5.06_win_x86_SSE2_OpenCL_ATI_r521.exe</name> <executable /> </file_info> - <file_info> <name>AstroPulse_Kernels_r521.cl</name> <executable /> </file_info> - <app_version> <app_name>astropulse_v505</app_name> <version_num>506</version_num> <avg_ncpus>0.04</avg_ncpus> <max_ncpus>0.2</max_ncpus> <plan_class>ati13ati</plan_class> <cmdline>-instances_per_device 2 -unroll 8 -ffa_block 8192 -ffa_block_fetch 4096</cmdline> <flops>209876543210</flops> - <coproc> <type>ATI</type> <count>0.5</count> </coproc> - <file_ref> <file_name>ap_5.06_win_x86_SSE2_OpenCL_ATI_r521.exe</file_name> <main_program /> </file_ref> - <file_ref> <file_name>AstroPulse_Kernels_r521.cl</file_name> <copy_file /> </file_ref> </app_version> - <app_version> <app_name>astropulse_v505</app_name> <version_num>505</version_num> <avg_ncpus>0.04</avg_ncpus> <max_ncpus>0.2</max_ncpus> <plan_class>ati13ati</plan_class> <cmdline>-instances_per_device 2 -unroll 8 -ffa_block 8192 -ffa_block_fetch 4096</cmdline> - <coproc> <type>ATI</type> <count>1</count> </coproc> - <file_ref> <file_name>ap_5.06_win_x86_SSE2_OpenCL_ATI_r521.exe</file_name> <main_program /> </file_ref> - <file_ref> <file_name>AstroPulse_Kernels_r521.cl</file_name> <copy_file /> </file_ref> </app_version> - <app> <name>astropulse_v505</name> </app> - <file_info> <name>ap_5.05r409_SSE.exe</name> <executable /> </file_info> - <app_version> <app_name>astropulse_v505</app_name> <version_num>505</version_num> - <file_ref> <file_name>ap_5.05r409_SSE.exe</file_name> <main_program /> </file_ref> </app_version> - <app> <name>setiathome_enhanced</name> </app> - <file_info> <name>MB6_win_x86_SSE3_OpenCL_ATi_HD5_r390.exe</name> <executable /> </file_info> - <file_info> <name>MultiBeam_Kernels_r390.cl</name> <executable /> </file_info> - <app_version> <app_name>setiathome_enhanced</app_name> <version_num>610</version_num> <avg_ncpus>0.05</avg_ncpus> <max_ncpus>0.05</max_ncpus> <plan_class>ati13ati</plan_class> <cmdline>-period_iterations_num 20 -instances_per_device 1</cmdline> - <coproc> <type>ATI</type> <count>1</count> </coproc> - <file_ref> <file_name>MB6_win_x86_SSE3_OpenCL_ATi_HD5_r390.exe</file_name> <main_program /> </file_ref> - <file_ref> <file_name>MultiBeam_Kernels_r390.cl</file_name> <copy_file /> </file_ref> </app_version> </app_info> Next up to try to figure out why it downloaded CPU WU's when I made the changes to the preferences. |

use Notepad to edit your app_info, as i said earlier. Claggy |

you have "instances per device" set to 2 but you have your count set to one so you are asking boinc to run 2 but each Wu uses the whole GPU which means you are basically having 2 WU's active but only processing 1 at a time.

Wasn't the change to change it to .5? <count>0.5</count> Also, now looking at the changes again, should I have made 'all' the changes twice, under each <cmdline>-instances_per_device 2 -unroll 8 -ffa_block 8192 -ffa_block_fetch 4096</cmdline> line? |

And at the moment there isn't any astropulse to download.... But you'll notice them as soon as they are available again. check seti server status page occationally.... http://setiathome.berkeley.edu/sah_status.html TRuEQ & TuVaLu |

Don't give it a second thought, if I paid a bit more attention I could have seen it was a second set.

<cmdline>-period_iterations_num 20 -instances_per_device 1</cmdline> missed the last one In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

<cmdline>-period_iterations_num 20 -instances_per_device 1</cmdline> What should the count be (0.5 like the others?), I just went back to look at prior posts and someones removed a bunch of posts. I don't remember that being one of the one's to change, but of course I could have missed it. Dan/Philly |

<cmdline>-period_iterations_num 20 -instances_per_device 1</cmdline> I'd say, leave that set of instructions as is. For now TRuEQ & TuVaLu |

<cmdline>-period_iterations_num 20 -instances_per_device 1</cmdline> Will do. |

I finally got a gpu task, let me know, if you don't mind, if everything is A OK. Thanks, Dan/Philly [edit] according to ccc, the gpu isn't running, must be only cpu, guessing??? |

Is it supposed to be running 1 or 2 WU's? It's running one which is fine by me unless it's supposed to be running 2, :) Here is the seti tasks running Hope I'm not pushing the gpu at 925 Mhz. |

Is it supposed to be running 1 or 2 WU's? It's running one which is fine by me unless it's supposed to be running 2, :) According to the advice you took to leave the instances_per_device and count for setiathome_enhanced at 1, it is correct that it is only running one. If you were real lucky and got two AP tasks they'd be able to run at the same time with your app_info settings. As the paused task shows nearly half done in 16:17, BOINC will try to adapt to that unexpected speed but it would be better if you had <flops> set for that app too. I don't know a value to advise, though. Ideally, setting <flops> for all applications is best, then the BOINC core client and the servers can most easily get estimates and work fetch right. Joe |
