[Qlustar-Announce] Qlustar Feature Update 02/20
by General announcements about Qlustar 13 Feb '20

13 Feb '20

A number of new Qlustar features were completed recently and published together with the latest security updates ([1], [2]). QluMan 11.0.3.1 has the following new capabilities: * The 'Write Files' dialog [3] got a complete revamp: + The configuration files/links belonging to different QluMan 'Config Classes' are now neatly arranged in a single collapsible tree-view. + Colored LEDs have been introduced to indicate whether pending changes of the config files are waiting to be written and which files are affected. + It is now straightforward to cycle through the list of changed files exclusively, allowing for a fast overview of pending changes in diff format. + Selecting individual Config Classes to be written has become a lot simpler by providing checkboxes in the tree-view. + Overall, the new dialog greatly enhances the clarity of the cluster configuration space. It provides way better control and confidence when performing configuration changes. * Messages for config file writing have been added to the QluMan Log Viewer [4]. * The so-called QluMan 'save-button interface' was improved and implemented for the editing of command names in the Command Editor. Now name labels turn green when changed and black after being saved, improving transparency. If you use QluMan singularity images, make sure you download [5] the latest version.

We are happy to announce a few new Qlustar features that we completed recently and were published together with the latest security updates. * QluMan is now capable of managing BeeGFS and Lustre mounts [1]. If you use QluMan singularity images, make sure you download the latest version [2]. * The tool qlustar-image-edit now allows for simple static OS image customization [3]. * OpenMPI 3.1.4 packages were added to Qlustar 11.0 in addition to the 4.0.x packages already available. It turned that a number of MPI codes had problems to be compiled with the 4.0.x version. In the future, we plan to introduce such non-interruptive features in irregular intervals, decoupled from the usual Qlustar releases.
