Hello, I am pleased to announce that PBS Professional version 2022.1.3 is now available for customer download on the PBS Professional User Area, Altair Connect, and Altair One Marketplace. While PBS Pro 2022.1.3 is primarily a bug fix release, support for RHEL 9, Rocky 9, and Ubuntu 22.04 for both x86_64 and ARM has also…
Hi all, We have a new Instructor Led Training offering about “PBS Pro v2022.1”. For more comprehensive information about “PBS Pro v2022.1”, please visit the Altair Learn site (https://learn.altair.com/) under Class Schedule to check for scheduled sessions and register if you are interested. Otherwise, you can contact your…
Reprise(TM) type licensing is only available for Accelerator products before the 2023.1.1 release. With the share=ui attribute in the license file, sometimes rlmstat reports more license handles checked out than what rlmstat itself reports as the sum of all license handles. This is because license handles with the same…
When does this page apply? The steps described on this page only apply to projects where nginx is used as a webprovider. For versions prior to 2021, there is no other webprovider than nginx. In versions 2021 and above you can check this via $ vovservermgr config | grep webprovider webprovider "nginx" If the internal…
You can be doing everything right — managing your HPC environment like a pro, orchestrating complex workloads, analysing performance and utilisation to get actionable results — but you can still get bogged down by the hidden bottlenecks that result from bad I/O patterns. Maybe you tested a workflow on one or two nodes,…
The days when “lift and shift” meant breaking a sweat are over, and more organisations than ever are lifting and shifting workloads to the cloud. But are they doing it the right way? Storage is often a secondary consideration when setting up HPC infrastructure, but it can make a critical difference when it comes to…
https://www.youtube.com/watch?v=UM_4bXs9J98 Achieving reliability in continuous bulk solids mixing processes is key to meeting product quality requirements in a wide range of industries but physical trial-and-error optimization is time consuming and expensive. This webinar demonstrates an efficient virtual optimization…
Life sciences center relies on HPC to accelerate the time to science to further our knowledge of the world and to save lives. The compute needs are often distinct from the requirements of more general HPC centers or other industry verticals. For example, the biologists and bioinformaticians at Bielefeld University’s Center…
There are some key properties of the GPU card specification that we can look at to determine how to select a GPU for Altair® EDEMTM. These are discussed below however to summarise we want a balance of the following properties: * FP32 and FP64 Performance (TFLOPS) * Bandwidth (GB/s) * Clock Speed (MHz) and Number of Cores *…
Cgroups are a powerful part of Linux that you can use to manage access to resources. This is critical in HPC where many users can share very large compute nodes and require isolation between their workloads. In this article we will look at what you can do with cgroups, how to use them, and how PBS Professional is…
