One more present from Santa - Qlustar 13
by Qlustar List 29 Dec '22

29 Dec '22

The Qlustar team is pleased to announce the immediate availability of Qlustar 13 for download [1]. It updates Qlustar's core platform to current Ubuntu 22.04 LTS. The AlmaLinux [2] edge platform remains based on 8.6 while CentOS 7 [3] is still supported via Qlustar 12 images and the new cross-version compatibility. The highlights of this release are the addition of BMC hardware management via IPMI/Redfish in QluMan, the integration of Spack as the new HPC package manager and the cross-version compatibility between Qlustar releases. QluMan's new *BMC hardware management* support allows for BMC authentification management, power control of nodes via IPMI or Redfish, the display of BIOS settings as well as their validation and correction. A cumulative problem report showing an overview of cluster node misconfigurations has also been added to QluMan. Spack [4] has been introduced as the new package manager for HPC related application software beyond the so-called *Qlustar HPC core stack*. It offers a huge list of supported software packages and by design provides hardware optimized versions of them. The HPC core stack is a new component definition within Qlustar and is related to the introduction of Spack. Rather than aiming to provide as much HPC functionality as possible by OS packages (debs/rpms), the HPC core stack now makes a clear cut between Qlustar related system software which remains provided as OS packages and HPC application software. Starting with this release, *cross-version compatibility* between the current and the previous Qlustar release has been added. In practice this means, that on a cluster with a Qlustar 13 head-node you can still run nodes with Qlustar 12 images/chroots and vice versa. This new feature was added to allow even smoother release upgrades. Highlights among the various *major component updates* include Kernel 5.15.x, Slurm 22.05.x, Lustre 2.15.1, ZFS 2.1.6 and BeeGFS 7.3.2. Please read the release notes [5] for more details.

Is it possible to add modules to qlustar linux kernel?
by pierre-yves.boelle＠upmc.fr 20 Dec '22

20 Dec '22

Hi all, I'm trying to set up Qlustar 12.0 with ubuntu focal on a HP machine equiped with a smart array controller P816i-a. The problem is that the smart array is not recognized after install: I can see it with lspci, but the disks are not listed in /dev. As far as I understand, this is a driver issue : the smartpqi module is required for this smart array. This module is available from "linux-modules-extra" in ubuntu focal 20.04, but this package is not part of the qlustar distribution. So questions : 1 - Is there a way I can simply add a required module (for example .ko file) in the qlustar kernel and simply recompile the qlustar kernel? 2 - failing that, should I expect trouble running qlustar with a "pure ubuntu" kernel ? If I add the focal repository in apt sources and install linux-modules-extra, I can build a new kernel OK, but it is "pure ubuntu" - not qlustar. Is qlustar kernel just a light version of the ubuntu kernel and that's ok? or does qlustar include extra components ? Any input appreciated PYB

Install Gaussian 16
by yohann.clement＠univ-lyon1.fr 19 Oct '22

19 Oct '22

Hello, I'm trying to install Gaussain 16 on Qlustar. I have some troubles to install it due to some right management. Indeed, Gaussian does not allow the directory on which it is installed to be accessible to others. The director should only be accessible to the owner and a group. I have created a group called gauss with Qluman in which I have added a user for a test. But the created group is not recognized in Chroot-focal. Could you tell me if you alreeady have installed G16 in Qlustar. If so could you kindly send me the procedure. Best,

Qlustar 12 and openmpi 4.0
by rolandas.naujikas＠mif.vu.lt 03 Oct '22

03 Oct '22

Hi, In my cluster I found problems running some MPI applications (for e.g. via mpi4py) and it is related to defaults in /etc/openmpi/4.0/openmpi-mca-params.conf. When I changed btl to ^openib or to vader,selft,tcp (in case tcp nodes) - it started to work, but in this case it doesn't use UCX anymore. Regards Rolandas
