Anyone have one of these they’ve been crunching on?
----------------------------------------Been looking into building an ARM SBC cluster and the ability to run Android is certainly a selling point in terms of project support. Not too many real benchmarks comparing it to the RP4B, however.  |

Not sure if I can answer your question but I am running a small Odroid N2 cluster, see this post: https://www.worldcommunitygrid.org/forums/wcg...d,38025_offset,200#626581
----------------------------------------Based on the benchmark on hardkernel.com the Odroid N2 is faster than the new C4 Link to benchmark The N2 even comes with 6 cores, compared to 4 cores of C4. So maybe the N2 might also be an option for you? [Edit 1 times, last edit by KodeX at May 28, 2020 8:23:28 PM] |

Thanks for the reply! Nice setup you have there.
----------------------------------------I'm actually already crunching on an Odroid N2! It’s a great device, running OPN on all cores and getting slightly better WU runtimes than an RPI4B (OC’d to 1.8GHz). I was considering buying a couple more, but was curious about the C4 due to the lower price and compatibility with RPI cluster cases. |

The cluster case is a valid point. I do not understand why there are no cases to buy for building N2 clusters. Online you find some instructions how to build your own case (even manuals that you can print on a 3D printer) but there is no case ready to buy. Hardkernel could also have made it stackable (like HC2) so you do not need a case at all... but they didnt.
That's why I had to build my own setup for my N2s  .It would be great if someone can share experience with a C4 cluster (performance and temperature). I am thinking about adding a 2nd cluster in winter. Not sure which system I will choose though. So please keep us updated if you have new info  |

Speaking of Odroid clusters, there's also the ODROID-MC1 : My Cluster One with 32 CPU Cores and 8GB DRAM for $220. Each unit has a Samsung Exynos 8-core (bit.LITTLE?) SoC, but it's 2 GB RAM for all 8 cores.
----------------------------------------I wonder how performance of the MC1 compares to the N2. My preference is good Linux support so I can install just the bare minimum OS and services just to run BOINC (or whatever) vs. the overhead and bloat and privacy concerns of Google Android or AOSP/LineageOS.

The cluster case is a valid point. I do not understand why there are no cases to buy for building N2 clusters. Agreed. It's too bad, ODroid seems to be doing a great job with software support but their hardware accessories always seem to be lacking. So please keep us updated if you have new info Will do! I figure I'll probably end up picking one up for testing in the near future. From what I can tell, the C4 seems to perform similarly to a stock RP4B - which is interesting, considering the A72 should be a much superior design over the A55. Would be nice if we could get a list of SBC performance going in the forums. Speaking of Odroid clusters, there's also the ODROID-MC1 : My Cluster One with 32 CPU Cores and 8GB DRAM for $220. Each unit has a Samsung Exynos 8-core (bit.LITTLE?) SoC, but it's 2 GB RAM for all 8 cores. Per ODroid benchmarks, performance of a MC1 solo seems not too far off from an N2. That said, I just feel iffy about purchasing something so old - the A15 was released about 8 years ago. Besides the lack of RAM, the processor consumes over twice as much power per core. My preference is good Linux support so I can install just the bare minimum OS and services just to run BOINC (or whatever) vs. the overhead and bloat and privacy concerns of Google Android or AOSP/LineageOS. Hear you 100% on that. PITA to manage my N2 vs my RP4B. Here's hoping WCG support more ARM for Linux projects in the future. Even support for one more project (say, MCM) would be a big deal for me. |

Maybe for just OPN1 crunching and not thinking of the future, the Raspberry Pi 4B 2 GB model that is now $35 is best bang for the buck. The Odroid N2 2 GB model is $75, so for that price we can buy two Pi 4Bs (8 cores) vs. just 6 core.
----------------------------------------If we think with more flexibility like running Rosetta@home or other future projects, maybe buying Pi 4B 4 GB models at $55 will keep them in production longer. For individual projects like a Home Theater PC or video game emulator, Odroid N2 seems much better. But I feel that because the Pi has such a massive community, the software support is more guaranteed. Raspi OS, Debian, Ubuntu, Kali, Win10 Core, LibreELECT, etc. @KodeX's cluster behind the TV running without fans, silently, 1 Watt/core still makes me jealous. But I don't know if I want to spend 5 x $75.
