If you run more than one cluster, administration means logging into each one separately. With 9.1.5 Qontrol handles the whole fleet from a single console. The MCP server is not part of that. It stays...
HPCKP is an open knowledge project around HPC, AI, and quantum science, and the annual meeting brings together people who run clusters for a living. The conversations are about what actually works in...
There is a new whitepaper over at HPC Gridware about Qontrol, the web based admin console for Gridware Cluster Scheduler. The scheduler offers a depth of control other workload managers miss, but...
We've just released Open Cluster Scheduler 9.1.0 and Gridware Cluster Scheduler 9.1.0. This is a big one. The headline feature is a completely redesigned topology-aware binding framework. Binding is...
For years I ran this blog on a very old, outdated CMS. It had been unsupported for a long time, and I had zero interest in maintaining it. My only interest was writing about things I found important...
We are pleased to announce the availability of GCS/OCS 9.0.11, the latest patch release in the 9.0 series. This release delivers a focused set of improvements and bug fixes, including enhanced qrsh...
GCS/OCS provides a flexible resource management system that has been refined over many years. Integrating new resources—whether quantum computers, tape libraries, cloud instances, hardware...
Gridware Cluster Scheduler 9.0.10 based on Open Cluster Scheduler 9.0.10 (fka. Grid Engine) is now available. This is a patch release with fixes accumulated over the last month. If you want to give...
We just published a whitepaper describing how Open Cluster Scheduler (fka Grid Engine) is installed on NVIDIA's DGX SPARK (and compatible workstations), improving AI researchers' efficiency by adding...
We're pleased to announce the release of Gridware Cluster Scheduler 9.0.9 (based on Open Cluster Scheduler 9.0.9 - fka Sun Grid Engine), bringing powerful new capabilities for license management, job...
Gridware Cluster Scheduler supports munge authentication in daily builds since a while, bringing enhanced security to containerized workloads. This widely-adopted service runs as a separate daemon,...
Current and future CPUs offer more than just cores and sockets. HPC schedulers require information about L3, L2 caches, cache groups (like AMD's CCX), and power/efficiency cores to allow scenarios...
Grid Engine introduced the parallel job concept to the scheduler domain decades ago, laying the foundational groundwork. In today's AI age, multi-node computations are the essential building blocks...
Updated 2025-08-18 Migrating to Open Cluster Scheduler (OCS) or Gridware Cluster Scheduler (GCS) is straightforward and provides significant advantages for HPC environments. The schedulers offer...
The job priority system that was refined over years continues to be one of the most sophisticated features in Open Cluster Scheduler and its fully supported companion, Gridware Cluster Scheduler. Yet...
Release Date: 2025-07-08 We're pleased to announce the release of Gridware Cluster Scheduler 9.0.7, built on Open Cluster Scheduler 9.0.7 (formerly known as "Sun Grid Engine"). This release continues...
Update (July 21, 2025): Newer versions are now available! You can install OCS 9.0.6 or 9.0.7 for testing using: curl -s...
The Model Context Protocol (MCP) defines a powerful and simple protocol for AI applications to interact with external tools. Its key benefit is modularity: any tool implementing an MCP server can be...
I'm excited to share our latest podcast, which explores the release of Gridware Cluster Scheduler 9.0.5 — built on the new Open Cluster Scheduler 9.0.5! Once again, I turned to NotebookLM to...
Over at HPC Gridware I recently published a blog post highlighting how Gridware Cluster Scheduler (formerly known as "Grid Engine") can significantly simplify GPU management and maximize efficiency...
