For those who may be interested, a seti app has just been added for android using nativeboinc. |

Hmm only 40 days for an estimated completion time on my myTouch 3G Slide. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

My s3 was showing 59 hours to completion at the beginning. After 30 minutes the time had dropped and 5% was completed, however then I got an error. Maybe it's not quite ready for prime time yet. |

Hi. I published debug version (available here:http://files.nativeboinc.org/debug/seti-debug-distrib.zip). This version generates /mnt/sdcard/seti_fault.txt, which contains info necessary to catch bug (for me). Please, download file, put in some directory named as 'SETI@Home.zip' and install via 'Update from sdcard'. I didnt expect segfaults. thank you. PS: Can you give me work_unit.sah file for debugging? It would be great help for me. |

So far 0.386% complete @ 10 minutes runtime on all four cores. Nexus 7 JB 4.2.2 Estimating 50 hours 55 minutes to completion. This host. Edit: First wu's it downloads are vlars. Go figure. </Tazz> |

PS: Can you give me work_unit.sah file for debugging? It would be great help for me. You want the v6 PG series (4 short Wu's of different Angle Ranges) from eithier MB test WUs 1/2 or MB test WUs 2/2, Lunatics Test and Benchmark Tools If you can get the KWSN Linux MB Bench v2.01.08 bench program working under Android then great, that'll help to see if the Wu's will validate.

Thank you Claggy. But I am interesting your failed workunit (it will be great help, when you could save your failed workunit, if possible). If you can, please install debug version. Information generates by this version will helpful for me. It generates only info about faults. thank you. |

And you really really want to build a V7 app at a revision not earlier than r1671 or you'll find your work pretty much obsolete in a few weeks. Never learned my way around the repository properly but I think https://setisvn.ssl.berkeley.edu/svn/seti_boinc/ has the stock v7 build and https://setisvn.ssl.berkeley.edu/svn/branches/sah_v7_opt/ has optimised cpu, CUDA and OpenCL code. No idea which might be the easiest to port from for Android. A person who won't read has no advantage over one who can't read. (Mark Twain) |

i compiled version from repository. This is 'sah_v6'@1793 branch. I didnt use sah_v7, because it didnt provided by server (workunit was available for sah6). |

i compiled version from repository. This is 'sah_v6'@1793 branch. Oh right. V7 is in beta - setiweb.ssl.berkeley.edu/beta sah_v6 is outdated - previous release. We're about to transition to V7. The difference between V6 and V7 WUs is additional tags in the WU header: <autocorr_thresh>17.8</autocorr_thresh> <autocorr_per_spectrum>1</autocorr_per_spectrum> <autocorr_fftlen>131072</autocorr_fftlen> that tag is used by the opt apps to switch between code with and without autocorrelation. Our devs may be able to help you further. I don't code I'm just there for the unimportant bits. (like doing installers) A person who won't read has no advantage over one who can't read.

Thank you Claggy. But I am interesting your failed workunit (it will be great help, when you could save your failed workunit, if possible). The Wu of mine that failed can be got from here: http://boinc2.ssl.berkeley.edu/sah/download_fanout/17/16oc12ad.3218.143753.206158430224.10.105.vlar I'll get that debug app installed in the morning.

Currently, I am running my app under valgrind to catch bugs (ofcourse, it is computing failed workunit). I am waiting for results. |

Thank you Claggy. But I am interesting your failed workunit (it will be great help, when you could save your failed workunit, if possible). Debug app is installed, and is crunching away on the next Wu O.K Claggy |

Thank you. Unfortunatelly I couldnt catch bug with using valgrind :-O (!!!). My HTC sensation was computing a failed workunit over hour and couldnt catch bug. (I was trying, valgrind works fine). I can try later. I suspect, that bug is in boinc api (possible, that can be encountered when app works under a boinc client). thank you |

Yes. Theoretically. I added support for ARMv6 VFP and ARMv7 NEON. I was testing app for VFP and NEON. yesterday, I ran seti app (from boinc client) on HTC Wildfire S with ARMv6. Works fine. |
