Howard Chu @ SymasPro-tip: answers I wrote about <a href="https://mastodon.social/tags/LMDB" class="mention hashtag" rel="nofollow noopener" target="_blank">#LMDB</a> on monero.stackexchange.com are specific to LMDB in the <a href="https://mastodon.social/tags/monero" class="mention hashtag" rel="nofollow noopener" target="_blank">#monero</a> codebase. They are not applicable anywhere else.<a href="https://www.threads.net/@shbekti/post/DInw_GguYja" rel="nofollow noopener" translate="no" target="_blank">https://www.threads.net/@shbekti/post/DInw_GguYja</a>In particular, while 32- and 64-bit builds of Monero use a fully compatible DB format, that isn't true by default for LMDB.LMDB was not written to be a generic system library, and people using it as such (cough redhat cough) are morons. It's intended to be built into specific applications, with build flags set as needed.

Howard Chu @ SymasMeta Open Materials 2024 (OMat24) Dataset"The OMat24 dataset contains a mix of single point calculations of non-equilibrium structures and structural relaxations. The dataset contains structures labeled with total energy (eV), forces (eV/A) and stress (eV/A^3). The dataset is provided in ASE DB compatible <a href="https://mastodon.social/tags/lmdb" class="mention hashtag" rel="nofollow noopener" target="_blank">#lmdb</a> files."<a href="https://huggingface.co/datasets/facebook/OMAT24" rel="nofollow noopener" translate="no" target="_blank">https://huggingface.co/datasets/facebook/OMAT24</a>Note - distributing reference data in LMDB files isn't really recommended, since LMDB files are byte order- and wordsize-dependent.
