Altair® Access™

HPC Job Submission Portal for Researchers and Engineers

Access provides a simple, powerful, and consistent interface for submitting and monitoring jobs on remote clusters, clouds, and other resources, allowing engineers and researchers to focus on core activities and spend less time learning how to run applications and moving data around.

Remote visualization and collaboration capabilities bring access to expensive, high-end 3D visualization datacenter hardware right to the user.

User Experience

Users get a simple, powerful UX that's consistent across desktop, web, and mobile.

Optimized Resource Management

Integration with Altair® PBS Professional® allows optimized application provisioning on graphical and computing resources for maximum utilization.

Zero Data Movement

Only pixels are transferred, eliminating the prohibitive times associated with data transfer.


Access provides continuity of remote application sessions across network connectivity disruptions.

Open Architecture

Because Access is built on an open architecture, you can use third-party applications without needing additional software development.
