The recent SIESTA school produced a few valuable leftovers (apart from funny experience of hosting events on Discord). Those appear, most importantly, in a form of updated SIESTA Tutorials & Documentation , but not only.
There was also a set of video lectures prerecorded and released before the start of the school (as is trendy these days). The YouTube playlist is available here:
 Work in progress, where "progress" stands for organizers' tremendous efforts to deliver the general part of materials in time for the event, as well as to keep the project up-to-date afterwards.
While preparing one other talk I've ran into a funny feature of Paperscape that allows to view a graph of references or citations of a certain paper on arXiv. Moreover, such graph can be referred as a link (as stated in this post).
So here is the citations' projection of the original SIESTA paper onto the arXiv manifold - the overall number of citations of that publication is one order of magnitude higher, spanning over 11,5+k citing papers in total!
Funny thing, according to Miguel Pruneda that long-distance connection with "dark matter" area must be through a work on electronic stopping power for detectors. Or it may as well be a clustering artifact...
And connected is one new star in this sub-Universe, referring to its massive predecessor: SIESTA: recent developments and applications. Their relations are visible on the - yet not very bright - references graph (mind the "heavy star" to the bottom right):
The man-made Hell of dependencies management in HPC software has an
efficient way out: Spack, initially
established at Lawrence Livermore
and actively community-supported manager of program packages and
libraries for supercomputing. It's like e.g. Portage for Gentoo,
but system-agnostic, and does not pollute user's environment since
packages are linked through
RPATH at compile-time instead of through
dynamic (re)setting of environment variables at runtime (as is
pefrormed by hierarchical module systems like
This allows for the impressive
explained in a well-written documentation,
making Spack a very useful cluster management tool.
But not only. A careful reader will be happy to see in it a killer app for actual code development in the chaos vortex of academic & research software.
