Industry-leading Workload Manager & Job Scheduler for HPC

 

What is Altair PBS Professional?

Altair PBS Professional is a fast, powerful workload manager designed to improve productivity, optimize utilization and efficiency, and simplify administration for HPC clusters, clouds, and supercomputers. PBS Professional automates job scheduling, management, monitoring, and reporting, and it's the trusted solution for complex Top500 systems as well as smaller clusters.

Why PBS Professional?

Industry-leading Workload Manager

PBS Professional is the trusted solution for complex Top500 systems as well as smaller cluster owners.

Fast Throughput

Tested to 50,000+ nodes, Altair PBS Professional scales to support millions of cores with fast job dispatch and minimal latency, supporting 1,000,000+ jobs per day.

Unparalleled Security

Altair PBS Professional is the only workload manager to have achieved EAL3+ certification and the only workload manager offering integration with RedHat’s SELinux “cross-domain security” (or “MLS” — multi-level security) technology*

Key Features

Powerful, Policy-driven Scheduling

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.

Fast, Reliable Startup of Huge MPI Jobs

PBS Professional is tested at tens of thousands of MPI ranks and minimizes delays caused by faulty nodes.

No Graphic

Support for Linux Control Groups

Cgroups eliminate resource contention so jobs run faster and don’t interfere with each other or the OS.

No Graphic

Topology-aware Scheduling

PBS Professional optimizes task placement for all HPC network topologies (including any topologies built on InfinibandC and GigE, as well as vendor-proprietary technologies), improving application performance and reducing network contention.

No Graphic

GPU Scheduling

Support for advanced GPU scheduling, the ability for a job to separately allocate each individual GPU on a node, means you can share a single node among multiple jobs where each job requires its own GPUs.

No Graphic

Enterprise Resilience

A highly-redundant automatic fail-over architecture with no single point of failure means jobs are never lost, and they'll continue to run despite server failures, network failures, and even killing PBS daemons themselves.
