AWS HealthOmics introduces resource fallback order for WDL workflows

AWS HealthOmics introduces resource fallback directive for WDL workflows, enabling researchers to define ordered lists of preferred accelerator types with automatic fallback options.

• Define ordered accelerator preferences with configurable timeouts for each profile
• Automatically fallback to alternative accelerators without workflow resubmission
• Include CPU instances as final fallback to increase task reservation likelihood
• Reduces time spent diagnosing and resubmitting runs due to accelerator constraints
• Available across all AWS HealthOmics regions globally

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