failing on aarch64 platform.

Any clues?

All I can think is that your ld doesn't like elf_aarch64, from the log 
your posting it looks that's being injected from the FreeBSD ports 
system. Looking at the man page for ld on Linux it says:


  -m emulation
   Emulate the emulation linker.  You can list the available 
emulations with the --verbose or -V options.


So I'd guess you'd need to look at what that version of ld supports and 
then update the ports system to match.


Good luck!

All the best,
Chris

[slurm-users] Convergence of Kube and Slurm?

[Dan Healy via slurm-users]

Bright Cluster Manager has some verbiage on their marketing site that they
can manage a cluster running both Kubernetes and Slurm. Maybe I
misunderstood it. But nevertheless, I am encountering groups more
frequently that want to run a stack of containers that need private
container networking.

What’s the current state of using the same HPC cluster for both Slurm and
Kube?

Note: I’m aware that I can run Kube on a single node, but we need more
resources. So ultimately we need a way to have Slurm and Kube exist in the
same cluster, both sharing the full amount of resources and both being
fully aware of resource usage.

Thanks,

Daniel Healy
