Don't see it on my Intel Xeon 1366 systems.
For them time is the same.
It why it was puzzling me.

I've noticed that new 0.19 application is slower then previous one. I had a time about 1:40 for one WU but now the time is above 2 hours.

Is it only in my environment?

Got it from here:
http://de.eu.odroid.in/ubuntu_18.04lts/N2/

ubuntu-18.04.2-4.9-mate-odroid-n2-20190325.img.xz


Thank you. Installation from the scratch has allowed to run all those commands successfully.

It must be a problem on your host.
Try to reboot the host and try it again.


Yes, it seems so. Reboot didn't help.
I'll start from a fresh installation - could you please provide me exact url where you did get the ISO?
Just to be on the same page.
Thank you.

Have you run this lines:
sudo apt install libstdc++6:arm64
sudo apt install libstdc++6:armhf

The last line is for the missing lib.


Same error:
odroid@odroid:~$ sudo apt install libstdc++6:arm64

I have the orginal Hardkernel image Ubuntu 18.04.2 (MATE DESKTOP) for N2.
uname -a show :
Linux n204 4.9.184-37 #1 PREEMT Wed Jul 10 02:50:15 -03 2019 aarch64 aarch64 aarch64 GNU/Linux

You must run all the 5 lines one after the other.

I have this done on all of 9 x Odroid-N2 and it works.


Seems I have the same. Nevertheless:
odroid@odroid:~$ sudo dpkg --add-architecture armhf
odroid@odroid:~$ sudo apt update

Probably line in bold is a hint to root cause.

My odroid can't crunch anymore:

Process creation (../../projects/universeathome.pl_universe/BHspin2_19_arm-unknown-linux-gnueabihf) failed: Error -1, errno=2

uname -a
Linux odroid 4.9.184-37 #1 SMP PREEMPT Wed Jul 10 02:50:15 -03 2019 aarch64 aarch64 aarch64 GNU/Linu

This application was working fine: BHspin2_17_aarch64-unknown-linux-gnu
but not last one - BHspin2_19_arm-unknown-linux-gnueabihf

My Odroid-C2 and Odroid-N2 run with Universe BHspin v2 v0.19 arm-unknown-linux-gnueabihf without problem.
https://universeathome.pl/universe/show_host_detail.php?hostid=526961

On the Odroid-N2 with this:

sudo dpkg --add-architecture armhf
sudo apt update
sudo apt install libsfstdc++6
sudo apt install libstdc++6:arm64
sudo apt install libstdc++6:armhf

And in the cc_config.xml this:
<options>
<alt_platform>arm-unknown-linux-gnueabihf</alt_platform>
</options>



Thank you. What exact version of OC are you using?
I have tried on
Linux odroid 4.9.184-37 #1 SMP PREEMPT Wed Jul 10 02:50:15 -03 2019 aarch64 aarch64 aarch64 GNU/Linux

but got:

I have some problems with aarch64 linker...

Is it possible from a server side to enforce the using of old application in this case?

I'm having the same error.
Should it be fixed on a server side?
