I agree with the original poster.
I have built a "Tower of Power" with 12 RPI4, stacked on top of each other. They're even all booting via PXE from a separat other PI, so there is no local storage. They complete a OPN1 unit in around 9 hours when I run it on all 4 cores (faster if I overclock) and it uses only about 5 watts! That is almost unbeatble perforfmance per wH. It is a shame that it can only run open-pandemics. So please start support ARM on some other projects. kind regards Ole |

Hello,
one question: If a project can be calculated on ARM, does this mean, that it can be done on a Raspberry Pi computer. Is this the only - of course positive - consequence of becoming available on ARM? Or would it mean that the project would be faster on smartphonens, too, because it uses the "normal" chip of the smartphone and its ARM chip, i.e. both processors? The background of this question: I read, that some smartphones use ARM architecture chips. The question is, do they use it as main processor or do some smartphones have a normal "main" processor and an additonal ARM co-processor? Sorry, but I do not know much about smartphones......and about advantages and disadvantages of ARM achitecture,too....... Could someone explain, please? Thanks Martin S |

ARM is an alternative CPU architecture to X86 (Intel, AMD, etc).
----------------------------------------Most Smartphones these days have an ARM-type processor as their main processor/System-on-Chip. If you have a Smartphone, you most likely have it running on an ARM-Type Processor that can be manufactured by many companies such as Qualcomm or Mediatek or Samsung. WCG and other BOINC projects have ARM apps for Android OS phones, which use the ARM CPU cores to crunch tasks. The OPN project is also available for Linux running on ARM hardware. Yes, Raspberry is ARM-based and thus capable of crunching tasks. With Android, Raspberry can run SCC, OPN and MCM just like any Android Smartphone. Under Linux, it can only run In comparison to x86 processors, ARM uses a LOT LESS power but is also significantly slower. The performance/watt is more efficient, however, than x86 processors.  - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz [Edit 4 times, last edit by Falconet at Jan 22, 2021 10:13:32 PM] |

Thank you for the really good explanation.
I see things clearer now. To me personally setting up a Raspberry is hard. As I already said, I tried once, and failed. Now the machine lies unused somwhere in the corner. Well, sometimes things do not work. Some day, I will try once again. I want to save energy and run WCG, both. And for this, as you explained, a Raspberry seems to be a good deal. Thank you once again for the explanation. |

All of my PI4's are ruunning Raspbian (Linux) and they can only run OPN1 - not MCM.

You are welcome, Martin.

I also like to kindly ask for more projects with linux on arm support.
----------------------------------------Have already 10xOdroidC4 running WCG and another 5 are in soon. Of course it would be great to be able to support more than just OPN with them. BR
