- Appliance Job Queuing System
  Jobs queuing system and its main reasons are described.
- Appliances on Altair One
  The cloud infrastructure on Altair One for running the Jobs/Sessions App is known as an appliance. These appliances serve as the cloud-based counterparts to HPC clusters, including Access Web, PBS workload manager, and Altair applications.
- Applications on Altair One
  Altair One supports major solvers and interactive applications.
- Data Management
  Upload files to Altair Drive to submit jobs and access data using a remote desktop session.
- Monitor Job
  The jobs submitted to an appliance can be monitored from the Jobs application. The launch button for interactive applications is available in the Altair Marketplace for each appliance.
- Jobs
  Simulation jobs can be submitted in multiple ways to the default Jobs Apps or Altair One NavOps appliances, depending on user preference.
- License Requirements
  Altair One uses the managed Altair Units (AU) to perform its functions.
- License Utilization
  License utilization guidance can referred in the Administrator's application, Managed License.
- Sessions
  Altair One offers access to the latest Altair Applications through remote desktop sessions, without downloads and installations.
- Altair One HPC Support Request
  The goal is to support Altair One users and run simulations uninterrupted.

Appliance Job Queuing System

Jobs queuing system and its main reasons are described.

Jobs may queue on appliances for two main reasons:

Insufficient Resources: When all nodes are occupied, new jobs have to wait until running jobs complete, and resources become available.

Node Start-up: The nodes on the appliance are in a DOWN state and cannot run a job immediately. A node that has not been used for 10-15 minutes is turned off. The start-up time varies from 2 to 18 minutes, depending on the node type. For graphical nodes, it typically takes around 2 minutes for the node to become ready.

When a user initiates a session on an appliance, it requires a node in the "UP" state or powered on. Nodes that have been idle for more than 10-15 minutes are powered down. Consequently, there can be a 3-4 minute wait for a session to become available for use.

Wait times when requesting a new remote desktop session follow these steps:

User creates a session request.
Interactive job is queued for access.
Running the interactive jobs begins.
If a free node in the "UP" state is available, the job starts immediately (within 1 minute).
If no free node in the "UP" state is available, the system checks for node availability.
- If no nodes are available, jobs remain in the queue until a node becomes free.
- If nodes are available, additional nodes are powered on, and the session starts after a 3-4 minute delay.
