My phone seems to cruch and then go idle at irregular intervals for no apparent reason. Like others have stated, phone crunching is not worth the time and effort, atleast for the time being, when compared to a low cost PC. I want to finish this one WU that I have, just so that I have tried it. |

Regarding "worthless" of smartphone crunching. If look from some point of view ALL SETI classic crunching is worthless. Cause it was done with so slow PCs that we could repeat that search now in few weeks if not days perhaps. But, w/o that initial attempt would we have current state of computing art with BOINC, modern GPU computing and so on? If all would just refuse to use slow PCs and await some more powerful ones in the future and say "it's not worth to crunch on PC, they should get supercomputer for this or just not bother us with such tasks" - what future would be? If market will see real need in faster and more stable smartphones there will be such smartphones. If they don't need now they never appear! So, even if single today's tablet can't provide even 1/100 of computing power of today's GPU I think it's worth to use them. It will be worth for the future, not for current number of processed tasks. SETI apps news We're not gonna fight them. We're gonna transcend them. |

I guess I was wrong. There does seem to be a place for phone crunching. I have been wrong before, and I'm sure I will be wrong again. :D Steve Warning, addicted to SETI crunching! Crunching as a member of GPU Users Group. GPUUG Website |

Hmmmm ... Author of this article should mention NativeBOINC too, not only initial BOINCoid attempt... But in other aspects it's in line with my own vision :) SETI apps news We're not gonna fight them. We're gonna transcend them. |

Regarding "worthless" of smartphone crunching. No actually those were some very fast computers at the time. We aren't comparing modern PC's to old PC's we are comparing a cheap PC now to a smart phone. for the same cost one can get a quad core rig that is a much better cruncher than any smart phone currently on the market. Perhaps in 10-20 years when the smartphone chips mature they may be a viable option. One has to also assume that PC chips and equipment will likely get better at a similar pace.

Raistmer does make a very valid point though. Pushing the limits on a smart phone will make them faster. Will they replace a home computer. I dont think a phone will. But im thinking the Tablet might some day. We have kids today who have never seen a rotary dial phone. or a typewriter, or its replacement the word proscessor. Have never seen a phonograph or a tape deck. I like smartphones. Its nice to google directions or find a business address while your in the car, Or look up and see if your team is winning. But Jeez the damn view screen is way to small. So you guys go on and push the limits, Lets see how far you can take it. [/quote] Old James |

I think it's time for someone to start an SoCUG (SoC Users Group) team;) In fact I bet a lot of GPUUG members were kicking and screaming about how they where never gonna abandon CPU crunching in the early CUDA days. And like those comments made five years ago in 2008, half the comments in this thread are most probably doomed to sound pretty funny in (say) five fears time. Don't forget OpenCL and CUDA might be breaking out on ARM in the next 12 months, while Intel seems to finally be taking its Atom procs seriously (they should be quite nice for SETI @around 14nm-10nm). But the future tech I'd really love to see for SETI would be the ability to hook up an external GPU (eGPU) to a tablet or smartphone (or at least a laptop for that matter). |

Thank you Claggy. But I am interesting your failed workunit (it will be great help, when you could save your failed workunit, if possible). Because the first two Wu's hadn't completed with the debug app, (there was a lot of runtime and the app seemed to keep stalling, so when NativeBoinc got suspended ~9 hours was removed from runtime each time) I then put on the Stock 0.1 app, those two Wu's, and a few after then errored: All tasks for computer 6951520 Claggy |

Thank you. May be in next week I will publish special a boinc client version to catch similar bugs. Currently I dont know how to do it. Very likely is a boinc api bug. |

So far about 100 hours in on my old phone & only about 900 more hours to go. A whole new meaning to ET phone home. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

First task finished on Samsung mini: 122h Update: Samsung's result: validated OK versus NV GTX460 result. G-Tablet's reuslts: both validated OK (versus NV Ti550 and i3 Intel CPU). SETI apps news We're not gonna fight them. We're gonna transcend them. |

So far about 100 hours in on my old phone & only about 900 more hours to go. Looks like at 144 hours in, or maybe before that, something went wrong. Several restart at 100% and ended in error. Waiting to get another task and see how that goes. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

Tasks on my Nexus 7 are taking around 25 hours for Normal AR, and a bit under 8 hours for Shorties. Claggy |

My phone just reported in after 97 hours of crunching. It popped up errors twice but continued, so was doubtful. But happy to see that the WU has been validated and awarded 100 credits. Although initially I wanted to crunch just one WU, now I am eagerly waiting for the servers to start sending out new work. |

Hmm, every 20 sec it's restarting, and still 0.00 % completed :(( What's wrong?! |

Hmm, every 20 sec it's restarting, and still 0.00 % completed :(( I had a similar issue when I tried running it from the SD card in my phone. Moving it back to internal storage made it run OK.

I had a similar issue when I tried running it from the SD card in my phone. Moving it back to internal storage made it run OK. After I moved from SD back to phone I had to abort current task & get a new one. It has been OK, for me, since then.
