AWS HealthOmics added a resource fallback directive for Nextflow workflows, allowing specification of preferred accelerators with a defined fallback order, including CPUs. This helps bioinformatics users avoid manual resubmission of tasks when designated accelerators are temporarily unavailable.
The feature supports configurable timeouts per accelerator to balance wait time and fallback speed and is applicable across multiple AWS regions where HealthOmics operates. This enhancement improves resource utilization efficiency and workflow continuity during constrained accelerator availability scenarios.
