It turns out that libstdc++6 is already installed and that the libsfstdc++6 doesn't apply to my platform. It's for armhf and I running aarch64.

My Odroid-N2+ run with orginal Hardkernel image (aarch64).
To run Universe@home i have armhf support added.

Well, maybe Jesus can tell us what's missing for sure. I am running Einstein@home WU's with no problems right now.

Thank you for implementing ARM. My Raspberry Pi 4 is (2 GHz OC) producing valid results at around 2h15m runtime. My ASUS Tinker Board 2 produces valid results at around 6h45m.

Is Myocyte is a 64-bit only application, or is there any hope for an armhf-App like on the SiDock-Project?

Best regards

I tested it now on Odroid-N2+, Odroid-M1, Odroid-C2 and Odroid-C4 running with Ubuntu 20.04.1 LTS/20.04.4 LTS.
All work fine.

Just curious for benchmarks on Odroids.
How many minutes?

Ah, ok, thank you (i think that everybody doesn't publish their pcs...)

Got 4 on my Pi4. It's predicting 4h per WU. I'm running Raspberry Pi OS Buster.

Hello,

4h per WU on RPi4 is quite a lot. If i may suggest, update your OS (if you can & have the time). ARM provided a new, optimized math library implementation into glibc around version 2.30 or so, can't remember exactly. But it makes quite a difference. Non-overclocked RPi4 with reasonably up2date OS is able to run DENIS tasks at around 2h.[/quote]

I have compiled it from source for my RPi running in 32bit mode, so it definitely can be done.

Hi!
Probably the problem comes with a library dinamically linked. We have uploaded a new version for ARM forcing the static link to try to solve the issue. Could you check the new app? Especially the ones with problems. Thank you!

Regarding the 32bit application. Yes, there is no problem to compile it for 32 bits. We have started with 64, but if it is of interest, we could also compile it for 32 bits. Once we see that everything is going well, it shouldn't be a problem.

Best,
Jesús.

OK
I have just downloaded the new version 0.19 for the moment everything is fine.

The new 0.19 app is very slow.

Thank *you* Jesús! My Odroid-N2+ is working on four DENIS tasks now.

Hi JagDog,
This could be caused by the static compilation. We will check a different set of options to try to improve this. Thanks for the information.

Best,
Jesús.

Hi Jesús,

i noticed release of Version 0.20 for ARM64 an wanted to give some feedback. My observed avg. runtimes (Raspberry Pi 4B 2 GHz OC):

0.18: ~ 2h15m
0.19: ~ 3h40m
0.20: ~ 3h05m

Best

Good Morning, I also just realized the release of Beta 0.20, all of those WUs ended with computation error.

Hi Felix!
I've been checking your tasks, and I detected that your processor is ARMv7. As far as I know ARMv7 is 32bits, but our application is for 64 bits. I think the problem could be there.

Best,
Jesús.

Hi Jesús,

thanks for your reply, this is good to know. Has this changed from beta 0.19 to beta 0.20?
Because all 0.19 WUs finished without error.
