<options>
<alt_platform>arm-unknown-linux-gnueabihf</alt_platform>

All my Odroid-C2 with Linux16.04 get no new work. With the BHspin all works fine. But can get no BHspinV2 WUs. Some will run dry soon. From the log: Universe@Home 04.08.2016 13:53:42 Sending scheduler request: To fetch work. Universe@Home 04.08.2016 13:53:42 Requesting new tasks for CPU Universe@Home 04.08.2016 13:53:44 Scheduler request completed: got 0 new tasks Universe@Home 04.08.2016 13:53:44 No tasks sent On my Odroid-XU4 with Linux15.04 i get BHspinV2 without problem. |

The Linux is Ubuntu I suppose? Yes it is Ubuntu 16.04. (computers of type aarch64-unknown-linux-gnu) With <alt_platform>arm-unknown-linux-gnueabihf</alt_platform> in cc_config.xml. |

To be honest, I have no idea why new Ubuntu doesn't getting WU's. Odroid in my home works currently under Ubuntu 14.04 and have tasks all the time now... Krzysztof 'krzyszp' Piszczek Member of Radioactive@Home team My Patreon profile Universe@Home on YT |

With the BHspin WUs there was no problem to get WUs. Maybe the problem is that the BHspinV2 wu are send to ARM-Linux, ARM-Android, and so on. I see at the BHspinV2 wu that the wingman has the same sort of CPU/system. At the BHspin is it mixed. Has the server problems to send wu to some type of hosts? There are no messages why no work was sent. |

In BHspin2 WU's have to be send to the same architecture because 32 and 64 bits system have different precision in some double calculations and results files are not always identical... Krzysztof 'krzyszp' Piszczek Member of Radioactive@Home team My Patreon profile Universe@Home on YT |

Can it be that this is the problem for the server? Odroid-C2 is 64 bit architecture with 64 and 32 bit Linux. aarch64-unknown-linux-gnu with <alt_platform>arm-unknown-linux-gnueabihf</alt_platform> in cc_config.xml. |

I think this can be a problem, as application is compiled on 32 bit system on RaspberyPi... I will try compile application on Ubuntu under Odroid Today, but this will require probably new platform for ARM64 platfor in homogoneus redundancy...

JagDoc, can you manualy run application (outside of BOINC folder with the same param.in file on both platforms, please? I'm curious if application will work correctly and if results files have same content... Krzysztof 'krzyszp' Piszczek Member of Radioactive@Home team My Patreon profile Universe@Home on YT |

Executable and parameter file (param.in) you will find in /slot folder in the machine which get WU's. It should work on second system as well. Just run it in any folder by start executable file manually. Krzysztof 'krzyszp' Piszczek Member of Radioactive@Home team My Patreon profile Universe@Home on YT |

Also, I tried update my Ubuntu 14.04 to newest version but installation fails, so I'm now build Debian Jessie on Odroid and will play with it tonight. Krzysztof 'krzyszp' Piszczek Member of Radioactive@Home team My Patreon profile Universe@Home on YT |

Executable and parameter file (param.in) you will find in /slot folder in the machine which get WU's. Now it runs on Odroid-XU4 with Ubuntu 15.04 and Odroid-C2 with Ubuntu 16.04 manually outside boinc in seperate folder. Now we have to wait until finished. |

Great :) If it runs properly I can just add platform for your devices :) I will do this tomorrow as is late now :) Krzysztof 'krzyszp' Piszczek Member of Radioactive@Home team My Patreon profile Universe@Home on YT |

Great :) Both hosts (xu4 and c2) have finished without problem. The data0.dat files look to be identical. |

JagDoc, can you try it now, please? BTW, it is still 32bit application as I haven't 64bit ARM system, but it should work :) Krzysztof 'krzyszp' Piszczek Member of Radioactive@Home team My Patreon profile Universe@Home on YT |
