AWS HealthOmics introduces resource fallback order for Nextflow workflows

AWS HealthOmics introduces resource fallback directive for Nextflow workflows, enabling automatic fallback between preferred accelerator types and CPU instances without resubmission.

• Define ordered list of preferred accelerator types with CPU fallback option
• Automatically moves through alternatives when preferred accelerator unavailable
• Configurable timeout per accelerator profile controls fallback speed
• Reduces time diagnosing and resubmitting runs due to accelerator constraints
• Available in all AWS HealthOmics regions globally

Resource fallback helps researchers keep production bioinformatics workflows running by eliminating manual resubmission when accelerators are unavailable.
