Yes. in theory, although whether it’s worthwhile presumably depends on whether that RAM saving is significant. If you’re saving, say, 100MB on a 32 GB node, that’s not a vast saving, especially if you’re taking a maths performance hit with it. Might make
an interesting experiment with some real-world code, I suppose!

The only place I regularly encounter is in containers, so people who are running singularity might find their users are using alpine in a way they can’t easily see. Presumably the libm point Janne made applies in the container context as well, since the application
will presumably be using the container’s libm, not the host node’s library.<o:p class=""></o:p></div>

Recently been giving alpine linux a try. I am super impressed on virtualized version of it what a low ram footprint it has 60mb starting. What do you guys think when it comes to alpine linux in the HPC space?<o:p class=""></o:p></div>
