Found it, I should have asked to my puppet as it's mandatory in some places :-D It is simply

scontrol show hostname gpu[01-02],node[03-04,12-22,27-32,36]

Sorry for the noise

Hi all,
I remember seeing on this list a slurm command to change a
slurm-friendly list such as

gpu[01-02],node[03-04,12-22,27-32,36]

into a bash friendly list such as

gpu01
gpu02
node03
node04
node12
etc

I made a note about it but I can't find my note anymore, nor the
relevant message. Can someone please refresh my memory? I'll be
more careful with such a note this time, I promise!

Thanks and happy new year!

Hi,

My 2 cents: I have collected various Slurm hostlist commands in this Wiki page:

https://wiki.fysik.dtu.dk/Niflheim_system/Slurm_operations/#expanding-and-co...

Best regards, Ole

I always forget that one as well ("scontrol show hostlist" works in the opposite direction) but I have a workaround at hand:

pdsh -w gpu[01-02],node[03-04,12-22,27-32,36] -N -R exec echo %h

You may use "-f 1", if you prefer a sorted output. (I use to pipe the output through "xargs" most of the time, too.)

We use a tool that's compiled against the Slurm library itself so that the expansion/contraction of lists is always 100% in sync with Slurm itself:

Wonderful. Thanks Ole for the reminder! I had bookmarked your wiki (of course!) but forgot to check it out in this case. I'll add a more prominent reminder to self in my notes to always check it!

Happy new year everybody once again

Ole,

I added a brief "how to build" to the README.md, hope that helps. I also commented on your issue on Github — your environment doesn't seem to have the slurm.h header that's expected. What version of Slurm are you running?

Hi Jeffrey,

Thanks a lot, I'd like to try out snodelist. Not knowing much about CMake, I couldn't build the tool :-( I've opened an issue on GitHub: https://github.com/University-of-Delaware-IT-RCI/snodelist/issues/1 Can you help me out?

As cited on the issue, between Slurm 23.02 and 23.11 the defined type `hostlist_t` was changed by the developers. Prior to 23.11 it was an opaque pointer to a hostlist_t data structure; in 23.11 it is the data structure itself. This means that all hostlist API functions changed, as well, to directly use `hostlist_t*` arguments instead of `hostlist_t` arguments. The snodelist code was written against pre-23.11 releases of Slurm where `hostlist_t` is an opaque pointer. So in post-23.11 situations — where it's a data structure, not a pointer — the compilation fails because there is no definition of `struct hostlist` present in the header.

Very annoying, but I added a version-based adaptation in the source to get around it. Should compile on 23.11 and newer now...unless there are other big changes they made to the API :-)

Hi Jeffrey,

We run Slurm 24.05.5. I now used the RockyLinux 8.10 versions of gcc and cmake according to the instructions in README.md, but the build is still failing.
