Spack 0.22.0 problem with zlib-api
by tiagomeloalmeida＠ua.pt 22 Jul '24

Dear Qlustar Team, I apologise if this isn't the appropriate channel for such report. If there's a better place to direct this question, please let me know. I believe I've encountered a bug with the recent update of Spack in the Qlustar HPC Core Stack 24.06. After upgrading my Qlustar system (both chroot and head-node, using 'apt update' followed by 'apt upgrade'), I started receiving the following error when attempting to install packages with Spack: ==> Error: Package 'spack.pkg.builtin.zlib-api' not found. Use 'spack create' to create a new package. Did you mean one of the following packages? libkcapi grib-api libcap Upon investigation, I found a relevant change in Spack itself: https://github.com/spack/spack/commit/e51748ee8f89e0d3db4e426e3d04157129a45… This change introduces a new virtual 'zlib-api', which replaces 'zlib' in most packages to allow users to switch to zlib-ng by default for better performance. However, I noticed that the /etc/spack/defaults/package.json file was missing the definition of this virtual library. I added the line "zlib-api": ["zlib", "zlib-ng+compat"] to the file, but I'm still encountering the same error. What am I missing? How can I resolve this issue? For reproducibility purposes: - Spack version: 0.22.0 (previous version before the update 0.20) - Command I'm running: spack install r Furthermore, I believe this would affect most of the installation packages in Spack, since zlib is used in alot of them. Thank you for your assistance. Best regards, Tiago Almeida

Hi, I'm trying to do a fresh install using 13.2-1 (Ubuntu) and noticed this error during the initial config; qlumand-apt-trigger: timeout the instal then finishes but when I try qluman-cli --gencert --debug All I get is; Error: Could not connect to server. I found in the logs it suggested slurmd was not running, but even after manually starting qluman-slurmd it gives the same error. Any ideas/suggestions? Thanks, Cyrus

Qlustar HPC Core Stack 24.06
by no-reply-list＠qlustar.org 29 Jun '24

29 Jun '24

The Qlustar team is pleased to announce the availability of the HPC Core Stack 24.06 for Qlustar 13. It was published together with the latest security bug fix update and can be installed by updating the Qlustar 13 chroots on the cluster. The HPC CORE STACK [1] was introduced with the release of Qlustar 13 as a new component definition within Qlustar. It is related to the introduction of Spack. This release includes the following individual major HPC core stack component updates: - Spack version 0.22.0 [2] - Slurm version 23.11.8 [3] - RDMA-Core version 52.0 [4] - HWloc version 2.10.0 [5] - UCX version 1.17.0 [6] The new version of Spack allows easy and direct access to the most recent compilers, MPIs and hundreds of other applications relevant to HPC. Note that the default OpenMPI version is now 5.0.3, a new major version. The latest 4.1.x versions were also tested to still build cleanly with this new Qlustar release. As part of this update, Qlustar AlmaLinux was moved to the 8.10 version which is now the only release supported by upstream. Minor version updates for other Qlustar 13 components are also included, in particular Lustre (2.15.5) and gdrcopy (2.4.1) for use with Nvidia GPUs.
