The AWS Simple Queue Services (SQS) and pipeline cluster supports XNAT scale-out compute capability. This provides a more robust environment for handling multi-user peak periods.

Instruction

XNAT uses AWS SQS (Simple Queue System) to manage and queue the jobs. At the moment, a maximum of 6 concurrent jobs can be executed in XNAT pipeline cluster. All the submitted pipeline jobs will be queued in XNAT system and also the AWS SQS.

The pipeline cluster caters to running small pipeline jobs (single core, requires less than 4-6GB RAM for each job), as it is consisted of up to 3 VMs, each VM (2vCPU and 8GB RAM) can run maximum 2 concurrent jobs. Jobs requiring more than 4-6GB RAM or multiple CPUs should consider running on Artemis. Please refer to the User guide to run jobs in Artemis. 


There is no change on how to run pipeline in XNAT. Please refer to the below link for how to run a pipeline in XNAT
