Key Features
Exascale Computing
Exascale means massive compute power, and PBS Professional is built to orchestrate and optimize the demands of exascale and beyond: 50,000 nodes in a cluster, 10 million jobs in a queue, and 1,000 concurrent active users. Many of the world’s biggest computing systems use PBS Professional to power efficient workload management, and today’s exascale systems will have widespread implications for the future.
Powerful, Policy-Driven Job Scheduler
PBS Professional accelerates job execution and selects optimal job placement across diverse, broadly distributed resources. It’s easy to create intelligent policies to manage distributed, mixed-vendor computing assets as a single, unified system. PBS Professional is topology-aware and supports GPU scheduling.
Budget Allocation and Cost Control
Manage budgets across your enterprise — on-premises, in the cloud, and for multiple clusters — by allocating your users credits for PBS Professional workloads. Credits can be provided in one or more customizable currencies. To give you visibility into HPC usage, PBS Professional includes full reporting of credit consumption by groups and individual users.
Unparalleled Security
PBS Professional is the only workload manager and job scheduler to have achieved EAL3+ certification and the only workload manager offering integration with RedHat’s SELinux cross-domain security (or multi-level security, MLS) technology.
Modern Web-Driven Interface
PBS Professional’s powerful GraphQL interface provides job and node status operations. It includes common job submission, deletion, and alteration commands; job and node status queries; and an interactive API to craft queries.
Enterprise Support
PBS Professional is backed by HPC experts around the world to ensure your computing environment operates optimally. Our developers continually work to enhance PBS Professional with the latest technologies and advancements, resulting in world-class solutions and customer support.
