I don't know how many people on this list will be familiar with Termux or Arch
Linux. From a quick Google, it looks like Termux is an Android emulator (that
runs on Android? That doesn't make sense to me, but I'm wholly unfamiliar with
that ecosystem, so I don't have the background / grok the
Do you think executing mpirun as a normal user will work?

Yes, it's self-learning.
I have no applications to run.

I'd imagine the builders of Arch Linux on Termux would want to know why
OpenMPI is not functioning as expected.

You asked several questions:

That's fine, but Apache has different requirements than Open MPI.

If it didn't work as root, it most likely won't work as a
As far as I can see, this is either a configuration issue, an issue with
OpenMPI's implementation or an issue with Arch Linux on Termux.
Only the first is resolvable by myself given the right inputs.

Is SELinux running on ArchLinux under Termux?

Yeah, the ldd output for Arch Linux is as follows:
linux-vdso.so.1 (0x007fab461000)
libopen-rte.so.40 => /usr/lib/openmpi/libopen-rte.so.40
(0x007fab374000)
libopen-pal.so.40 => /usr/lib/openmpi/libopen-pal.so.40
(0x007fab296000)
libc.so.6 =>
How do I know that? I'm not a Linux expert. I simply want to get OpenMPI
running on Arch Linux so that I can test out their Java wrappers which I
obviously can't on Termux since it doesn't support OpenJDK.

Nope. None of the commands exist. So no, I'd say.

I am not familiar with Termux - it runs on Android. Surely it should
simply make an ssh connection into the remote system.
Why then libandroid-shmem?

As far as I know, Termux does things a bit differently from the usual Linux
suspects.
And their OpenMPI version works for nodes on the same device.

So the OpenMPI version on Arch Linux can't be made operational?
